301 vs 302 redirects in WordPress – best practices explained

Are you wondering what the difference is between 302 and 301 redirects?

Redirects are important for providing a great user experience and helping search engines understand your site better. 302 and 301 are types of redirects that you can use for different situations.

In this article, we will compare 302 redirects versus 301 redirects. We’ll also show you the best practices when using redirects in WordPress.

302 vs 301 redirect – what’s the difference?

Redirection in WordPress allows you to send users and search engine crawlers to a different URL than the one they clicked on.

You need to set up redirects if you delete a page on your WordPress site, move to a new domain, or conduct A/B testing, and there are for sure many other reasons when you desperately need to create some redirect rules.

Without redirects, users would not see the content they requested. Instead, they’ll encounter a 404 error page, which is bad for your site’s user experience and search engine rankings.

When it comes to setting up redirects, you’ll encounter the two most common types: 301 and 302 redirects. Let’s look at each one and understand the difference.

What is a 301 redirect?

A 301 redirect is a permanent redirect. If your website or web page has been moved permanently to a new location, you can use 301 redirects to point users to the right place.

For example, when a visitor types your site’s address or clicks on a link, the 301 redirect will automatically change the requested address to the new address.

What is a 302 redirect?

A 302 redirect also helps point users and search engines in the right direction, but temporarily.

Unlike a 301, which is a permanent redirect, 302 redirects are temporary. You can move your website traffic to a new location for a limited time and then go back to the original URL whenever you want.

When should you use 301 and 302 redirects?

Now that you understand the main differences between the two types of redirects, you might be wondering when to use 301 and 302 redirects.

Depending on the conditions and your goals, it makes sense to use either 301 or 302 redirects.

When to use a 301 redirect?

Since 301 redirects are permanent, here are the scenarios when to use them:

Migrating your WordPress website to a new domain
Switching your site from HTTP to HTTPS
Moving a web page to a new location
Merging multiple pages and pointing them to a new page
Permanently changing your site’s URL structure

When to use a 302 redirect?

On the other hand, if you don’t want to permanently redirect your audience to a new page or location, then it’s better to use 302 redirects. Here are some situations where using a 302 redirect makes sense:

Conducting A/B tests for designs, layouts, or features of a new website or page
Temporarily redirecting users to a sales page or promotional offer
Sending users to the correct version of your website based on their language or location preferences
Collecting user feedback about a new product or service without impacting your current SEO rankings

Impact of 301 redirects vs 302 redirects on SEO

When deciding between 301 and 302 redirects, it’s important to consider their impact on your site’s SEO (search engine optimization).

Search engines use bots to crawl and index your website pages, following links to discover new content. Using the correct type of redirection ensures that your blog posts are easily discovered by search engine crawlers and maintain their rankings in search results.

301 redirects and SEO

A 301 redirect indicates to Google and other search engines that a site or web page has been permanently moved. This type of redirect transfers the full link equity (often referred to as “link juice“) to the new URL. Link equity represents the value passed from one site to another, helping the new URL to rank well in search results.

302 redirects and SEO

If the change is temporary, a 302 redirect is more appropriate. A 302 redirect tells search engines that the redirection is not permanent and does not transfer the full link equity. This way, the original page retains its SEO rankings, as search engines understand that the temporary page will eventually revert back to the original URL.

Best practices for implementing 302 and 301 redirects

Setting up redirection on your WordPress website can be complicated. To help you out, here are some best practices to follow:

Testing redirects to ensure they’re working

After you’ve set up 301 or 302 redirects, it’s essential to test each link multiple times to ensure they are functioning correctly. This is crucial because any issues with the redirection can negatively impact your site’s user experience and SEO rankings. A simple way to check is by visiting your site in incognito mode and opening the redirected link. If it opens the new location, then your redirects are working properly.

Additionally, there are free tools available online that can check redirection for you. Alternatively, you can use the AIOSEO plugin, which logs your redirects within your WordPress dashboard. For those who do not want to pay any monthly fees, there is always Google Search Console.

Google Search Console is a free tool that can be very useful for monitoring your site’s health, including redirects. By using the coverage report and checking for any issues, you can identify broken redirects and other problems affecting your website’s SEO. This tool is essential for any website owner to ensure that Google can crawl and index their site correctly. More information is available on the Google Search Console page. You can also use online tools like Redirect Checker to verify that the redirects are working as intended.

For complex sites, you will need more specialized SEO tools, which also have many other essential functionalities and features:

Marketing Miner – helps you track both 301 and 302 redirects, identify any issues, and ensure they are working correctly. Marketing Miner also provides detailed reports and insights, making it easier to manage your site’s SEO health. More information can be found on the Marketing Miner website.
Screaming Frog – is a widely used tool for auditing and analyzing website SEO. One of its key features is the ability to check for redirect issues. Screaming Frog can crawl your entire site, identify both 301 and 302 redirects, and highlight any redirect chains or loops. This tool is invaluable for maintaining your site’s SEO health by ensuring that all redirects are functioning correctly. Additionally, it provides comprehensive reports that are easy to understand and act upon. More information can be found on the Screaming Frog website.
Ahrefs Site Audit – offers a comprehensive site audit feature that can crawl your website and detect various issues, including problems with redirects. It checks for both 301 and 302 redirects and helps you identify any broken redirects or issues with redirect chains. By setting up regular audits, you can monitor your site’s health and ensure all redirects are functioning properly. More information can be found on the Ahrefs website.

This tool is particularly useful for on-the-fly checks and identifying redirect chains, ensuring that your redirects are functioning correctly in real time. You can add the extension from the Ayima website.

Most of these tools also can help you to monitor broken links.

Monitoring redirects for broken links

Next, it’s important to track broken links after adding 301 and 302 redirects to your website. If a web page is moved to another location or users are sent to a new page temporarily and the redirection fails, it will result in a broken link. Consequently, users will see a 404 error page, which can harm your site’s user experience and SEO rankings.

Tracking broken links after setting up 301 and 302 redirects allows you to fix them promptly, thereby maintaining a smooth user experience and preventing any negative impact on your keyword rankings. The best way to track broken links is by using the AIOSEO plugin. You can enable the ‘404 Logs’ feature to start monitoring for 404 error pages. Initially, you won’t see any data, as the plugin will only start recording broken links after the setting is enabled.

Once the plugin starts gathering information, you can view broken links on your site under the 404 Logs tab. To quickly fix 404 error pages, you can click the ‘Add Redirect’ option and set up 301 or 302 redirections. For more details, please see our guide on how to find and fix broken links in WordPress.

Avoid creating redirection chains and loops

A redirection chain occurs when multiple redirects are set up between the source URL and the target URL. Google officially follows up to 10 hops in a redirection chain. If there are more than 10 redirects, it could result in a redirect error in Google Search Console. To avoid this, it is best practice to minimize redirection chains and point directly to the new location of a website or page. This is particularly important when setting up permanent 301 redirects, as too many can cause errors and negatively affect user experience.

Additionally, it’s crucial to avoid redirection loops. A redirection loop happens when URLs in a chain redirect back to themselves, creating an infinite loop. As a result, users and search engines won’t reach the intended page and will instead see the original page or a ‘redirected you too many times’ error. To fix this, remove all redirects in the chain and redirect directly to the final destination.

How to fix redirection chains and loops

To fix redirection chains, you should audit your redirects and ensure each URL points directly to the final destination without unnecessary intermediate steps. Use tools like Screaming Frog or Ahrefs to identify and resolve these issues.

Preventing duplicate content

Another best practice for using 301 and 302 redirects is to avoid duplicate content issues, especially if your site uses multiple subdomains. For example, if your site’s URL has HTTP and HTTPS, www and non-www versions, or variations with capitalized and lower-case URLs, search engines may view these as separate sites, leading to duplicate content problems.

To fix this, redirect all subdomains to a single preferred URL. For instance, redirect both HTTP and non-www versions to the HTTPS www version. This consolidation helps prevent duplicate content issues and improves SEO.

Additional tips

Migrating sites – when migrating sites and domains, you might use a 302 redirect temporarily to indicate to Google and other search engines that the move is temporary and the content isn’t duplicated permanently. Once the migration is complete, set up 301 redirects to indicate the preferred version of the content for indexing.
Redirects monitoring – regularly monitor and audit your redirects to ensure they are functioning correctly and not causing issues. Tools like Google Search Console, Screaming Frog, Ahrefs, and SEMrush can help you identify and resolve any redirect problems efficiently. This is crucial for bigger projects which is dependent on your living. You can set up alerts, notifications, reports, etc.
Using canonical tags – in addition to redirects, using canonical tags can help manage duplicate content by indicating the preferred version of a webpage to search engines. This can be particularly useful for managing similar or duplicate content across different URLs.
Implementing SSL/TLS – ensure that all redirects point to the HTTPS version of your site to provide a secure browsing experience for your users. This not only improves security but also enhances SEO, as search engines favor secure sites.

How to redirect a website using the .htaccess file in WordPress

The .htaccess file is a configuration file used by the Apache webserver to manage redirects, among other functions. Here’s how you can set up redirects using the .htaccess file in WordPress:

Step 1: Locate the .htaccess file

Access your hosting account – log in to your web hosting account and navigate to the file manager.
File manager – open the file manager application provided by your hosting service. Alternatively, you can use an FTP client like FileZilla.
Locate the file – navigate to the root directory of your WordPress installation. This is usually the public_html or www directory. The .htaccess file is located here. Some hosting companies need to first allow you to use .htaccess, so better to contact your hosting first or check if they have some tutorial for that.

Step 2: Edit the .htaccess File

Backup the file – before making any changes, download a copy of the .htaccess file to your local computer for backup purposes.
Open the file – open the .htaccess file using a text editor within the file manager or download it and open it using a text editor like Notepad or TextEdit.

Step 3: Add redirect rules

Add the appropriate redirect rules to the .htaccess file based on the type of redirect you need for

301 redirect (permanent redirect): Redirect 301 /old-page.html http://www.yoursite.com/new-page.html
302 redirect (temporary redirect): Redirect 302 /old-page.html http://www.yoursite.com/new-page.html
Redirecting the entire site – if you want to redirect an entire site to a new domain, use: RewriteEngine On RewriteCond %{HTTP_HOST} ^oldsite\.com [NC] RewriteRule ^(.*)$ http://newsite.com/$1 [L,R=301,NC]
Non-WWW to WWW redirect: RewriteEngine On RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,R=301]
WWW to non-WWW redirect: RewriteEngine On RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC] RewriteRule ^(.*)$ http://%1/$1 [L,R=301]
Redirecting to HTTPS: RewriteEngine On RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Step 4: Save changes

Save the file – save the changes to the .htaccess file.
Upload the file – if you downloaded the file for editing, upload it back to the root directory of your WordPress installation, replacing the old file.

Step 5: Test the redirects

Test in browser – open your web browser and test the old URLs to ensure they are redirecting correctly to the new URLs.
Use online tools: You can also use online tools like Redirect Checker to verify that the redirects are working as intended.

Important notes

Backup regularly – always back up your .htaccess file before making any changes.
Syntax – ensure that you follow the correct syntax for each redirect rule to avoid errors.
Permissions – make sure that the file permissions allow for writing changes to the .htaccess file. This is typically set to 644.

By following these steps, you can effectively manage and implement redirects on your WordPress site using the .htaccess file. For more details, you can refer to WordPress Codex and Apache documentation.

A/B testing – what is it?

Leave a reply

Let’s start with the general A/B testing definition.

A/B testing, also known as split testing or bucket testing, is a method of comparing two versions of content to determine which one performs better. By testing a control version (A) against a variant (B), measures success based on key metrics such as conversion rates or user engagement. This technique is widely used in both B2B and B2C marketing.

Common applications include:

Website A/B testing – splits traffic between two versions of a webpage (e.g., copy, images, design, calls to action) to see which one results in higher conversions or desired actions.
Email marketing A/B testing – divides email recipients into two segments to test different subject lines, images, or calls to action, aiming to identify which version achieves a higher open rate.
Content selection – compares editor-selected content with algorithmically selected content based on user behavior to see which generates more engagement.

A/B testing is crucial for optimizing customer experience (CX) and can be extended to A/B/N testing, where “N” represents multiple variations beyond just two.

When and why to use A/B testing

A/B testing is most beneficial when implemented continuously, providing ongoing recommendations for improving performance. The nearly unlimited options for testing include:

Emails
Newsletters
Advertisements
Text messages
Website pages
Components on web pages
Mobile apps

A/B testing is vital for campaign management, revealing what resonates with your audience and what doesn’t. It helps identify which elements of your marketing strategy have the most significant impact, need improvement, or should be discarded.

When to A/B test:

Underperforming campaigns – if a digital marketing campaign or element isn’t meeting expectations, A/B testing can help isolate and address performance issues.
Launching new elements – before launching new web pages, email campaigns, or other digital assets, proactive A/B testing can determine the most effective approach by comparing different strategies.

By consistently applying A/B testing, marketers can optimize their strategies, enhance user experiences, and achieve better results across various digital channels.

Benefits of running A/B tests on your website

Website A/B testing is an effective method to determine which tactics resonate best with your visitors. It allows you to validate your hypotheses with data, ensuring you continue using only the most effective strategies. Even if your hunch is proven wrong, it’s a positive outcome since you avoid sticking with ineffective tactics. Successful A/B tests lead to increased visitor engagement, longer site visits, and more link clicks.

Testing commonly used website components and sections help you make informed decisions that can improve not just the test page but other similar pages across your site. This process ensures consistent enhancements in user experience and site performance.

How to perform an A/B test

A/B testing involves a systematic approach to ensure reliable and actionable results. Here are the nine fundamental steps to plan and execute an A/B test:

Measure and review the performance baseline – understand the current performance metrics of your website to establish a baseline.
Determine the testing goal – define what you aim to achieve with the test, based on your performance baseline.
Develop a hypothesis – formulate a hypothesis on how the changes you’re testing will improve performance.
Identify test targets or locations – choose specific elements or pages on your website to test.
Create the A and B versions – develop the control (A) version and the variant (B) version for comparison.
Utilize a QA tool – use a quality assurance tool to validate that your test setup is correct.
Execute the test – run the A/B test, ensuring both versions are equally represented to your audience.
Track and evaluate results – use web and testing analytics to monitor performance and gather data.
Apply learnings – analyze the results and apply the insights to improve the customer experience.

Following these steps with clear goals and a solid hypothesis helps avoid common A/B testing mistakes. The data and empirical evidence from these tests guide you in refining and enhancing your website’s performance. Continuous optimization through A/B testing leads to more engaging customer experiences, compelling content, captivating visuals, and ultimately, more effective marketing strategies. This, in turn, increases ROI and drives higher revenue.

By integrating these practices into your digital marketing efforts, you can ensure that your website consistently evolves to meet the needs and preferences of your audience, leading to sustained growth and success.

A/B testing examples

A/B testing can be applied to various digital marketing elements to optimize performance. Here are some examples of what can be tested:

Navigation links – experiment with different placements and labeling of navigation links to see which version enhances user navigation and engagement.
Calls-to-actions elements (CTAs) – test different cta text, colors, and placements to determine which combinations drive more conversions.
Design/layout – compare different page layouts and design elements to see which arrangement improves user experience and interaction.
Copy – test variations in the website copy, including length, tone, and style, to identify what resonates best with your audience.
Content offers – evaluate different content offers, such as eBooks, whitepapers, or webinars, to see which one attracts more interest.
Headlines – experiment with different headlines to determine which one grabs attention and encourages further reading.
Email subject lines – test various subject lines to find which ones lead to higher open rates.
Friendly email “from” address – see if changing the sender’s name impacts open rates and engagement.
Images – compare different images to see which ones drive more engagement and conversions.
Social media buttons – test the presence, placement, and design of social media buttons to see their effect on social sharing.
Logos and taglines/slogans – experiment with different logo designs and taglines to find which combinations strengthen brand perception and recognition.

Your business goals, performance objectives, baseline data, and current marketing campaign mix will help you determine the best candidates for A/B testing.

The role of analytics in website A/B testing

Analytics is essential throughout the entire lifecycle of an A/B test, from planning to execution and performance evaluation.

Planning stage

The development of a test hypothesis requires a strong foundation in analytics. Understanding current performance and traffic levels is crucial. Key data points provided by your analytics system during the planning process include:

Traffic – page views and unique visitors to the page or component being tested
Engagement – metrics such as time spent on the page, pages per visit, and bounce rate
Conversions – data on clicks, registrations, and fallout rates
Performance trends – trends over time to provide context for current performance level

Without a solid grounding in analytics, test scenarios may be based on assumptions or personal preferences, which are often proven incorrect by testing.

Execution stage in A/B testing

Once an A/B test launches, analytics plays a central role in monitoring and validating performance metrics in real-time. A performance dashboard helps track these metrics, ensuring the test operates as expected and allows for quick responses to any anomalies or unexpected results. Adjustments can be made, and the test can be restarted if necessary, ensuring that performance data accurately reflects any changes and their timing.

The performance dashboard also helps determine the duration of the test and ensures statistical significance is achieved before making any conclusions.

Post-test analysis in A/B testing

After the test concludes, analytics are used to determine the next steps. This may involve adopting the winning version as the new standard presentation on the tested page and potentially rolling it out to similar pages. Developing a reusable analytics template to convey test results and adapting it for specific test elements can streamline the process and enhance future tests.

By leveraging A/B testing and comprehensive analytics, marketers can continuously refine their strategies, enhance user experiences, and achieve better performance across digital channels.

How to interpret A/B test results

To effectively interpret A/B test results, it’s crucial to establish clear goals during the planning phase. This helps you evaluate the outcomes, determine a winner, and update your marketing campaign or website to reflect the successful version. Often, an audience is pre-segmented with a holdout group that receives the winning version of a message.

The test results will indicate the success of one element over another based on the metrics you’ve decided to measure, such as:

Number of visitors
Open rates
CTR/Click-through rates
Signups (for newsletters, etc.)
Subscriptions

During the test, the two elements are monitored until a statistically significant measurement is achieved.

Conversion rates can also be measured in terms of revenue. Consider sales numbers and the impact of a change on actual sales revenue. Remember, conversion rates can be captured for any measurable action, not just e-commerce sites and sales. These actions can include:

Sales
Leads generated/registrations submitted
Newsletter signups
Clicks on banner ads
Time spent on the site

What metrics should you pay attention to when it comes to A/B testing?

The metrics to focus on depend on your hypothesis and goals. However, you should prioritize metrics that indicate audience engagement with your marketing content.

For web pages – look at the number of unique visitors, return visitors, time spent on the page, bounce rates, and exit rates.
For email marketing – monitor who opens the email and clicks through to your CTAs.

By focusing on these engagement metrics, you can make data-driven decisions to enhance your marketing strategies and improve overall performance.

What is multivariate testing? How is it different from A/B testing?

Multivariate testing is often discussed alongside A/B testing, so it’s important to understand its distinct characteristics and how it differs from A/B testing. Although they are related, there are significant differences between the two.

Multivariate testing involves testing multiple elements simultaneously across one or more website pages or email campaigns to identify the combination that yields the highest conversion rate. It applies a statistical model to test various combinations of changes, leading to an overall optimized user experience and website performance.
A/B testing, on the other hand, compares two versions of a single element to see which one performs better.

Here are some key traits of multivariate testing:

Wide range of elements – multivariate tests involve a broad array of changes, including images, text, color, fonts, links, CTA buttons, and layout for landing pages or checkout processes. It is common for a multivariate test to exceed 50 or more combinations.
From hypothesis to results – multivariate testing begins with a hypothesis about content changes that could improve conversion rates. These changes are broken down into individual elements to determine the most effective combinations. Whether the changes are slight or significant, they can impact the overall results.
Conversion rates – the primary metric in multivariate testing is the conversion rate, which measures the rate at which visitors perform a desired action, such as clicking an offer or adding products to their cart. Additional metrics like revenue per order or click-through rate are also evaluated. Analytics help identify which combination of changes yields the best results based on the defined metrics.
Continuous optimization – multivariate testing allows for continuous optimization by defining a business goal and letting the software automatically optimize the visitor experience to achieve that goal. This process ensures that the most effective combinations are used to enhance performance consistently.

In summary, while A/B testing compares two versions of a single element, multivariate testing evaluates multiple elements and their combinations simultaneously. This comprehensive approach provides deeper insights into which combinations of changes work best together to achieve the highest conversion rates and overall website optimization.

Can you run A/B and multivariate tests on iOS and Android Apps?

Yes, you can run A/B and multivariate tests on iOS and Android apps. In 2020, mobile apps accounted for $2.9 trillion in e-commerce spending, a figure expected to rise by an additional trillion by the end of 2021. This growth isn’t limited to retail and e-commerce; mobile traffic’s share of total online traffic continues to increase rapidly. In many regions, mobile phones are more accessible than laptops, making them a critical part of the customer’s buying journey. However, due to smaller screens, the cart abandonment rate is higher on mobile (87%) compared to desktops/laptops (73%).

Optimizing your mobile app experience is crucial, but it requires the right tools to account for the limitations of iOS and Android platforms. Effective A/B and multivariate testing can significantly enhance user experience and reduce cart abandonment rates.

Visitor segmentation and segment clustering in multivariate testing

Not all visitors or recipients will respond the same way to a particular experience. A key advantage of multivariate testing is the ability to identify and target different visitor segments based on how they interact with various experiences. For example, new visitors might prefer a different experience than repeat visitors, leading to better overall results. Advanced systems can automatically suggest visitor segmentation, saving time by analyzing test results against numerous visitor attributes.

Targeting different experiences for different visitor segments can substantially increase conversion rates. Segmentation can be based on a wide range of visitor attributes, from environmental factors to behaviors, and can include customer data from systems like your CRM.

When to use A/B testing vs. multivariate testing

Deciding whether to use A/B testing or multivariate testing depends on the number of elements you need to test and the complexity of their interactions.

A/B testing is ideal when you have two versions of an element to compare. It’s straightforward and easy to understand, making it a good introduction to website and campaign optimization. It helps demonstrate the measurable impact of a design change or tweak.

Multivariate testing is better suited for testing multiple elements and their combinations. It’s useful when you want to compare various combinations of images, titles, or other elements on a webpage or email. However, more options require higher traffic to achieve statistically significant results. Testing too many elements simultaneously can lead to an overwhelming number of permutations, which most websites and email campaigns cannot support due to insufficient traffic.

How you can add an admin user to the WordPress when you do not have access to WP-admin (using database MySQL)

Leave a reply

If you’ve been locked out of your WordPress site, possibly due to hackers deleting your admin account, or in case you forgot your admin credentials, you can restore access by adding a new admin user directly to the database via MySQL.

Before making any edits to your MySQL database, always back it up to prevent data loss. Once you regain access to your website, you might need to follow our beginner’s guide to fixing a hacked WordPress site. Now, let’s learn how to add an admin user to the WordPress database via MySQL, but firstly how to get to the phpMyAdmin.

Specifically, you can add a new admin user through phpMyAdmin, a web-based tool for managing MySQL databases, you can regain control – phpMyAdmin provides a user-friendly interface that allows you to perform various database operations such as running SQL queries, managing users, and importing/exporting data, all through your web browser. Most top WordPress hosting companies include phpMyAdmin, which you can find in the Databases section of your hosting account’s cPanel dashboard.

Where to find URL to phpMyAdmin

If you don’t know the URL to access phpMyAdmin, here are a few steps you can follow:

Check your hosting provider – most hosting providers include phpMyAdmin in their control panel. Look for options like “Database Management” or “MySQL Databases” in your hosting control panel (e.g., cPanel, Plesk).
Common URLs – sometimes, phpMyAdmin can be accessed via common URLs like:
- http://yourdomain.com/phpmyadmin
- http://yourdomain.com:2082/phpmyadmin
- http://yourdomain.com:2083/phpmyadmin
Ask your hosting provider – if nothing above works and you still can’t find the URL, contact your hosting provider’s support for assistance. They can provide you with the exact URL and login credentials if needed.
Local Installation – if you’re running a local server (e.g., XAMPP, WAMP), phpMyAdmin is usually included. You can access it via http://localhost/phpmyadmin.

Down you can see how can look like admin of our hosting provider (Cesky-hosting.cz), where you have mentioned phpMyAdmin URL:

Web based myPHPAdmin example in current hosting provider interface

Web based phpMyAdmin example in current hosting provider interface

When you in our case open the URL click https://mysql.spolehlive-servery.cz/ you will see phpMyAdmin interface. You also need to know your WordPress database credentials (database name, user name and password) – you should also see that or find that in your hosting provider interface or you should be able to create/change them here.

Once you login in phpMyAdmin you will see displayed all the tables in your WordPress database.

You will need to make changes to the wp_users and wp_usermeta tables.

We will start by adding new users to the wp_users rows/records.

How to add a new user to the `wp_users` table in MySQL database via phpMyAdmin

First, locate and click on the wp_users = open the wp_users table (in some WordPress databases it can have different naming, so it can be named not just as wp_users but as some_different_prexif_users.

You have to check in database if you find similar record with similar name, or name which could be connected with users or record which will have same fields as in the screen below – means ID, user_login, user_pass, user_nicename, user_email etc.

This will display the current users listed in the table.

In the screenshot below, our demo website’s table has user IDs 1 and 2.

phpMyAdmin – user interface – wp_users with current MySQL records

When we create a new user for our demo site, this ID needs to be unique, so we’ll type the number 3.

Click the ‘Insert’ tab at the top of the screen to input the information for the new admin user.

Example how to insert new records in MySQL via phpMyAdmin

You will see now screen below – where you need to fill:

ID: pick a unique number (in our example, we’ll use 3)
user_login: the username that will be used when logging in
user_pass: add a password, and make sure to select MD5 in the function menu (see the next screenshot below)
user_nicename: the user’s full name or nickname
user_email: the user’s email address – this email address is used also for new password change (here will be sent notification if you select that option during the new password creation process or here you will receive also email notifications for forgot/lost passwords as a normal user)
user_url: your website address
user_registered: select the date and time the user was registered using the calendar
user_activation_key: leave blank – this field is used to store a unique activation key for user accounts. It is often used during account registration or password reset processes. By setting this field to an empty string '', you are indicating that there is no activation key currently associated with this user. What does it influence?
- Account activation – the user can log in without needing to activate their account via an email link.
- Password resets – if the user needs to reset their password, a new activation key will be generated and stored here temporarily.
user_status: set this to 0
display_name: the user’s full name or display name

Once you have finished, make sure you click on the “Go” button to store the new user (you will find the save button in the down right corner – if the language settings is different you will see there different text instead of “Go”).

In phpMyAdmin, the language used for the interface is determined by the lang parameter in the configuration file or can be set manually by the user through the interface. When you access phpMyAdmin, it usually auto-detects the browser’s language settings and defaults to that language if it’s supported. Alternatively, users can manually change the language by selecting their preferred option from a drop-down menu in the phpMyAdmin interface, typically found in the top navigation bar. The available languages are based on the translations included in the phpMyAdmin installation.

This process will just create a new user, but we will also have to give him correct privileges/access rights. This is done via wp_usermeta tables.

Insert in MySQL in PHPmyAdmin - new user and MD5 encryption

How to insert a new record in MySQL in phpMyAdmin – new user and MD5 encryption – once you have finished, make sure you click on the ‘Go’ button to store the new user.

Why to use MD5 for the new user login password?

MD5, which stands for Message-Digest Algorithm 5, is a widely used cryptographic hash function that produces a 128-bit hash value. In MySQL via phpMyAdmin, it is often used to hash passwords. This means converting a plain text password into a fixed-size string of characters, which appears random. The primary purpose of using MD5 for passwords is to store them securely in the database, as the original password cannot be easily retrieved from the hash. However, it’s important to note that MD5 is no longer considered secure against modern threats, and stronger algorithms like SHA-256 or bcrypt are recommended for password hashing.

How to add privileges/access rights to a new user to the wp_usermeta table in MySQL via phpMyAdmin?

How to add privileges/access rights to a new user to the wp_usermeta – 1st part

To proceed, locate and select the wp_usermeta table. Click on the ‘Insert’ tab similar to the previous step. Fill in the Insert form with the following details:

unmeta_id: Leave this field blank (it will be auto-generated).
user_id: Enter the user ID you used in the previous steps when adding the new user to the wp_users table (in our case will be ID number 3).
meta_key: Enter wp_capabilities.
meta_value: Input a:1:{s:13:"administrator";s:1:"1";}.

This process assigns the necessary user meta information to create an administrator account.

Insert in MySQL in phpMyAdmin – new user rights in wp_usermeta

Here is a brief explanation, of what did you actually do:

unmeta_id – this is a unique identifier for each entry in the wp_usermeta table. You don’t need to enter anything here because MySQL will automatically create a unique number for it.

user_id: This is the ID of the user you created in the wp_users table. It links the user’s meta information to the specific user account. Make sure to use the same ID you used when creating the new user.

meta_key: wp_capabilities – this key tells WordPress what the user can do. It defines the user’s role and their capabilities.

meta_value: The meta_value of a:1:{s:13:"administrator";s:1:"1";} in the wp_usermeta table is a special code that WordPress uses to define user roles. Here’s a simple breakdown:

a:1: This means there’s one item in the list.
{s:13:"administrator";s:1:"1";}: This is the item in the list.
- s:13:"administrator": This part means the word “administrator” is the role.
- s:1:"1": This part means the role is active.

So, this code tells WordPress that the user is an administrator.

If you want to create a new user with an editor or other role in the database – the easiest way is to create an admin account first and then create new editors in admin directly.

How to add privileges/access rights to a new user to the wp_usermeta – 2nd part

After that, when you scroll down, you should find the same field names for a second row. You need to add the following information:

unmeta_id: leave this blank (it will be auto-generated)
user_id: the user ID you used in the previous steps
meta_key: you need to enter wp_user_level= it actually tells WordPress about the user’s access level.
meta_value: 10 = gives the user full admin rights

When you have finished entering the information into the fields, you need to click the ‘Go’ button. Congratulations, you have created a new admin username!

Insert in MySQL in phpMyAdmin – new user rights in wp_usermeta – second part of the table

Now, you should be able to log in to your WordPress admin area using the username and password you specified for this user.

After logging in, navigate to Users » All Users and click on the username you just created.

Without changing anything, scroll to the bottom of the page and click the ‘Save’ button.

This will allow WordPress to clean up the user you just created and add some extra information that is needed. When WordPress “cleans up” the new user you created, it means that the system is adding necessary background information to ensure the new admin user functions correctly. This includes linking the user to various settings, roles, and permissions that are essential for the user to have the appropriate access levels and capabilities within the WordPress admin area. This process ensures the new admin user can perform all tasks expected of an administrator, such as managing posts, plugins, themes, and other users, without running into issues.

Edit users/their user roles/admins in WordPress

This action allows WordPress to finalize the user creation and add any necessary additional information for the new user.

You can also use the similar process for edits of current records of users (for example you can change them their username, which is not normally allowed via WordPress admin interface – just go to wp_users and open any of the records in here).

WARNING! If your WordPress database has a custom table prefix rather than wp_ you’ll need to use that for the capabilities and user_level entries or you’ll get issues trying to access the dashboard (in our example in some screens you can see instead of wp_users value kr_users, same for wp_usermeta => you can see in our example kr_usermeta etc.). For example, if your database table prefix is wp_abcdef_ then you would use wp_abcdef_capabilities and wp_abcdef_user_level in the appropriate fields when inserting the wp_usermeta table record.

Also, it is easy to get confused in phpMyAdmin and new users often forget to press the Go button – so always click on Go button again when adding a record to be sure.

How to add new admin user to the WordPress database using a SQL query

If you are a developer, then you can speed up the process using code. It is actually just another version of doing the same thing a little faster (you do not need in our case understand MySQL

Simply drop this SQL query into your database:
INSERT INTO `databasename`.`wp_users` (`ID`, `user_login`, `user_pass`, `user_nicename`, `user_email`, `user_url`, `user_registered`, `user_activation_key`, `user_status`, `display_name`) VALUES ('3', 'demo', MD5('demo'), 'YourNicemame', 'demouser@demouseremail.com', 'http://www.krcmic.com/', '2024-06-01 00:00:00', '', '0', 'YourName');

INSERT INTO `databasename`.`wp_usermeta` (`umeta_id`, `user_id`, `meta_key`, `meta_value`) VALUES (NULL, '3', 'wp_capabilities', 'a:1:{s:13:"administrator";s:1:"1";}');

INSERT INTO `databasename`.`wp_usermeta` (`umeta_id`, `user_id`, `meta_key`, `meta_value`) VALUES (NULL, '3', 'wp_user_level', '10');Just ensure in this case that you replace `databasename` it with the actual name of your database. Same you have to do with wp_users and wp_meta in case the naming in your database is different (you use custom fields). Additionally, make sure to update the other values to the desired ones for the new user, as we described in the first method.

How to add an admin user in WordPress Using FTP – very easy tutorial

In case none of these methods mentioned above worked for you, there is also another option for how you can add a new user to WordPress – you can upload him directly via FTP.

There are certain scenarios where adding a WordPress admin user via FTP can be crucial:

Lost admin access – if you’ve forgotten your password, been locked out by a security plugin, or face issues with a plugin or theme preventing dashboard access, creating a new admin user through FTP can help you regain control.
Corrupted WordPress – common WordPress errors might block access to the admin dashboard. Adding a new admin user via FTP can restore your access.
Security issues – if your site gets hacked and admin access is compromised, creating a new admin user can help you regain control and secure your site.
Migration problems – during site migration to a new server, if the admin user fails to work or needs resetting, adding a new admin user via FTP can resolve the issue quickly.

With these scenarios in mind, we will guide you through the step-by-step process of adding an admin user to your WordPress site using FTP.

Why use FTP over phpMyAdmin and MySQL database changes

Using FTP to add an admin user in WordPress can be advantageous over phpMyAdmin and direct MySQL database changes in certain situations:

Accessibility – FTP can be accessed even when you cannot reach your WordPress admin area or phpMyAdmin interface due to server issues or lockouts.
Simplicity – FTP requires fewer steps and less technical know-how compared to executing SQL commands in phpMyAdmin.
Reliability – FTP allows you to upload files directly, bypassing potential database errors and ensuring changes are implemented immediately.
Security – if your database is compromised, using FTP to create a new admin user can help secure your site without exposing sensitive database operations.
Minimal dependency – using FTP can help recover from errors by allowing you to manually edit or replace corrupted files, ensuring that you have more control over the troubleshooting process.
Less risk of data corruption – FTP operations are less prone to cause database corruption compared to direct database edits, especially in the hands of less experienced users. This method is particularly useful for those who are more comfortable with file transfers and wish to avoid the complexities of direct database manipulation.
Error recovery – FTP does not depend on the availability of the database or web server, which can be advantageous during critical downtime or when other methods are inaccessible.

How to add a new admin user/new admin account in WordPress using FTP protocol

To start, you’ll need an FTP client. This software allows you to access your website files without logging into your WordPress dashboard. We’ll use FileZilla in this tutorial due to its ease of use.

First, connect to your website with the FTP client using your FTP access details, typically found in your hosting control panel.

For step-by-step guidance, refer to our guide on using FTP to upload files in WordPress.

Once connected, locate your current WordPress theme’s functions.php file. It is found in the following path:

/public_html/wp-content/themes/your-current-theme/

For example, if your site uses the default Twenty Twenty-Four theme, the path will be similar to this:

/wp-content/themes/twentytwentyfour/

Wordpress function.php - adding new user via FTP - default WordPress template

WordPress function.php – you can add new user also through FTP by editing functions.php file

Once you have located the functions.php file, double-click to download it using FileZilla (the file will be downloaded somewhere in your local drive – usually in the Downloads folder in case you did not select a different folder).

Also do not forget to create one more backup file of functions.php in case you change some code incorrectly and you will not be able to revert back your changes (for the complete new clean WordPress installation using the default Twenty Twenty-Four theme – there is very little chance you will do something wrong, but in older templates, you can do more harm in case you for example deleted some brackets or any other important piece of code resulting in site error). Creating a backup of everything is always a great habit. You can download the file and rename it – for example to functions.php07072024 (to be sure you will not accidentally rewrite it again and when you move it to the live, after the download you can rename it back to just functions.php). This will help you to keep a great overview of what you downloaded/what kind of version of code from your day you have.

Next, find the downloaded file on your computer and open it with a plain text editor like Notepad.

Insert the following code snippet at the bottom of the file to create an admin user account:
function wpb_admin_account(){

$user = 'Username';

$pass = 'Password';

$email = 'email@krcmic.com';

if ( !username_exists( $user ) && !email_exists( $email ) ) {

$user_id = wp_create_user( $user, $pass, $email );

$user = new WP_User( $user_id );

$user->set_role( 'administrator' );

} }

add_action('init','wpb_admin_account');

Don’t forget to replace Username, Password, and email@krcmic.com with your specific values. You can use the same code snippet to create other user roles if needed.

In default WordPress clean installation, the $user->set_role() function can assign the following roles:

Administrator = this user has full access to all admin features. Granting this kind of access privileges I already shared above.
Editor = can publish and manage posts, including those of other users. Then you will use the value 'editor'
Author = can only publish and manage their own posts, value 'author'.
Contributor = can write and manage their own posts but cannot publish them, value 'contributor'.
Subscriber = can only manage their profile, value 'subscriber'.

So in case you want to add an editor, you will in the whole code above change the value to this: $user->set_role( 'editor' );

Next, simply save the file and return to your FTP client. Locate the file you just edited on the left side of the interface. Right-click on it, and select ‘Upload.’

A window will pop up indicating that the file already exists in your website files. Choose the ‘Overwrite’ option and click ‘OK.’

In your FTP client new window will pop up saying that the file already exists in your website files, click yes as we want to overwrite the file

Now, navigate to yourwebsitename.com/wp-admin in your browser, replacing yourwebsitename.com with your domain name.

If the code works, you can log in to the WordPress admin area with your new credentials.

If the code works, you can log in to the WordPress admin area with your new credentials.

WARNING! Once logged in, return to your FTP client, open the functions.php file, and delete the added code to prevent it from executing again. Deleting the code won’t remove the user, but it ensures the script doesn’t run unintentionally or that any hacker will not use the same way to create another admin users also.

How to add a new admin user to WordPress with your web host’s file manager

If your FTP connection fails and you are still locked out of the WordPress admin, you can use your web host’s file manager to add an admin user. This method can be easier for beginners. Because usually hosting companies have their own cloud file manager and they look a bit less complicated than FTP managers, and also finding something like PSPad for free on a Mac is a long shot for complete beginners…

So how to start? How you can get to your hosting cloud file manager?

Firstly, you will just need to ask the hosting company about the URL/where in the hosting admin interface you find cloud file manager. Each hosting has it differently.

You will actually same folders as in FTP client.

When you log in to the cloud file manager, the rest of the process is actually the same.

You will need to get login credentials – so you need to create them or ask your hosting provider to let you know what values you should paste in. You will usually need to know the server, port, username, and password which are actually the same values you will use also when using classic local FTP managers like Filezilla or Total Commander etc.

This is how can look like the login page for web FTP client

Web FTP file manager and its view folder structure

You will locate your theme’s functions.php file.

You will download it to your local computer and create a backup of functions.php file.

Then you will paste the code snippet for creating a new admin user at the bottom of the functions.php file:
function wpb_admin_account(){

$user = 'Username';

$pass = 'Password';

$email = 'email@krcmic.com';

if ( !username_exists( $user ) && !email_exists( $email ) ) {

$user_id = wp_create_user( $user, $pass, $email );

$user = new WP_User( $user_id );

$user->set_role( 'administrator' );

} }

add_action('init','wpb_admin_account');

You will change the blue values above according to your needs.

Save it and new functions.php you will upload to the hosting and overwrite the old file.

Go to your WordPress login URL and sign in with your new admin user credentials.

Once you log in, you will remove the code from functions.php to prevent it from running again.

Why use an FTP client like FileZilla instead of a web FTP file manager

I personally recommend using an FTP client like FileZilla rather than web FTP file managers from hosters as it offers several advantages over web FTP file managers provided by hosting services companies.

For sure if you are a pure beginner and you have no plan to learn anything about web development, you can stick to web FTP managers from hosting companies. 🙂

Just to mention a few:

Speed and efficiency – FileZilla handles file transfers more quickly and efficiently, especially for large files or bulk uploads, as it is optimized for such operations. FTP clients like FileZilla can often transfer files at higher speeds due to optimized protocols and reduced latency compared to web-based interfaces.
Robust features – FileZilla provides advanced features such as pause and resume for transfers, a drag-and-drop interface, and detailed logs of your FTP sessions, which are often not available in web-based file managers.
Reliability – FTP clients are more stable for long file transfer sessions and can handle interruptions better than web-based managers, reducing the risk of corrupted or incomplete transfers.
Security – FileZilla supports secure FTP connections (SFTP), ensuring your data is encrypted during transfer. This adds an extra layer of security compared to some basic web-based file managers.
User interface – FileZilla offers a more intuitive and user-friendly interface, allowing easier navigation and file management compared to the often simpler and more limited interfaces of web FTP managers.
Multi-platform support – FTP clients like FileZilla are available for various operating systems (Windows, macOS, Linux), providing consistent functionality regardless of the platform.
Customizability – FileZilla allows users to configure settings according to their needs, such as connection retries, timeout settings, and custom commands, offering greater flexibility.
Batch processing – FTP clients can handle batch processing of files, enabling users to queue multiple files for upload or download, which is not always possible with web-based file managers.
Offline capability – FTP clients can manage files offline and queue them for transfer once a connection is available, which is useful for intermittent internet connections.

Link juice

Leave a reply

Link juice, a fundamental concept in SEO (Search Engine Optimization), refers to the value or equity passed from one webpage to another through hyperlinks. This concept plays a crucial role in determining a website’s authority, relevance, and ranking in search engine results pages (SERPs). Let’s delve deeper into what link juice is, how it works, and best practices for leveraging it to boost your site’s SEO performance.

What is link juice?

Link juice, also known as link equity, is the value and authority that a hyperlink passes from one page to another. When one webpage links to another, it transfers some of its authority and relevance, helping the linked page rank higher in search engine results. This transfer of value helps search engines understand the relationship between different pages and their importance within a website and across the web.

How link juice works?

Search engines like Google use complex algorithms to evaluate the quality and quantity of links pointing to a webpage. Here’s how link juice works:

Authority transfer – when a high-authority website links to your page, it passes on some of its authority, boosting your page’s credibility.
Relevance – links from topically relevant sites are more valuable. For example, a backlink from a tech blog to a tech-related site carries more weight than a link from an unrelated site.
Link quality – not all links are created equal. High-quality links from authoritative and relevant sites transfer more link juice than links from low-quality or spammy sites.
Anchor text – the clickable text in a hyperlink, known as anchor text, provides context about the linked page’s content. Relevant and keyword-rich anchor text can enhance the link juice transfer.
NoFollow vs. DoFollow – links can be marked with a “nofollow” attribute, instructing search engines not to pass link juice. Conversely, “dofollow” links allow the transfer of link equity.

Factors affecting link juice distribution

Several factors influence how link juice is distributed across web pages:

Page authority – pages with higher authority pass more link juice. Authority is often measured by metrics like Domain Authority (DA) and Page Authority (PA).
Number of outbound links – the more links on a page, the less link juice each link passes. A page with fewer outbound links distributes more link juice to each linked page.
Internal linking – effective internal linking helps distribute link juice throughout your website, enhancing the visibility of key pages.

Importance of link juice in SEO

Link juice is vital for SEO because it helps search engines:

Determine page authority – pages with more link juice are perceived as more authoritative and are likely to rank higher.
Understand content relationships – links help search engines map out the structure and hierarchy of content on a website.
Enhance crawlability – proper linking ensures that search engine bots can efficiently crawl and index a website’s pages.

Best practices for maximizing link juice

Create high-quality content – compelling, valuable content naturally attracts backlinks from authoritative sites.
Build relationships – networking with other site owners and bloggers can help earn valuable backlinks.
Guest blogging – writing guest posts for reputable sites in your niche can secure high-quality backlinks.
Utilize internal linking – strategically linking to your own pages helps distribute link juice effectively within your site.
Avoid link farms and spammy links – focus on earning links from high-quality, relevant sites rather than engaging in manipulative link-building practices.

Measuring and analyzing link juice

Several tools help measure and analyze link juice:

Google Search Console – provides insights into backlinks and their impact on your site’s performance.
Ahrefs – offers detailed backlink analysis, including link quality and authority metrics.
Moz – provides Domain Authority and Page Authority scores to gauge link equity.
SEMrush – offers comprehensive backlink analysis and competitive insights.

(Almost) everything you need to know about cookie management

Leave a reply

What does cookie management involve? Why are visitors constantly confronted with cookie banners, and most importantly, why is the world of cookies so confusing? Read on to uncover the answers!

How did cookie management come to be?

When cookies are used on a website, the online service provider stores a piece of information in the user’s browser. This cookie can be something as simple as a user’s preference for using a light or dark theme, so the service remembers the choice on the next visit.

The concept behind cookies is beneficial. When a visitor returns to a website, cookies can be used to retain their previous logins and shopping cart contents, making the user’s experience smoother and more convenient.

Cookies themselves are not inherently bad or problematic. The concern arises with how cookies are used and where the tags that utilize cookies send the collected information.

Larger operators began using cookies to track user activity across different sites on an individual level. In response, the EU introduced legislation concerning electronic communications and data protection, such as the ePrivacy Directive and GDPR, DMA (DIGITAL MARKETERS ACT), to safeguard individuals’ personal data by restricting this activity.

The problem isn’t with cookies that enhance the user experience. The issue arises when cookies are used to send data to other sites, such as analytics or advertising platforms, leading to the transfer of information between services.

This prompted the EU to decide that user consent must be obtained before storing any information on a user’s device. If the user does not give consent, storing the information is not permitted. An exception to this rule is cookies that are essential for the technical operation of the site or the transmission of a message. For cookies used for other purposes, such as analytics and marketing, managing cookies and obtaining cookie permissions became necessary.

The law, however, does not provide explicit guidelines on the precise use of cookies, leading to varied interpretations and implementations by different website operators. As a result, practices concerning cookie usage and consent can vary widely. Below in this article, more details about first-party and third-party cookies are provided.

But have these protective measures truly succeeded in safeguarding personal data and enhancing user experience?

The legislation introduced cookie banners, allowing users to control the storage of cookies.

Few users appreciate cookie banners. Requesting cookie consent often disrupts the browsing experience. These banners can also confuse many users, who may not fully understand cookies and their purposes.

To improve an online service, data on its performance is essential. Achieving this without cookies remains a significant challenge.

Super quick overview of the world of internet cookies

What are first-party cookies?

First-party cookies are set by the website that the user is currently visiting. They are typically used to enhance the user’s interaction with the website. These cookies help maintain sessions and remember login details, preferences, and shopping cart items. They allow for the customization of content and advertisements based on browsing history and interests, and they collect analytics to improve the website. Some first-party cookies provide essential functions for the website.

What are third-party cookies?

Third-party cookies are created by domains other than the website the user is visiting. These cookies can access visitors’ browsers through external services embedded in the site. Examples include:

An embedded YouTube video
A social media widget
An ad widget from an ad network

Third-party cookies are used for tracking users across websites, ad retargeting, and displaying targeted ads via ad platforms or social media. They enable brands and vendors to collect significant amounts of personal data, allowing the creation of detailed user profiles. However, they can also be used for malicious purposes, such as tracking users to steal personal information or deliver malware.

While third-party cookies facilitate functionalities like real-time chat services, their absence typically does not affect the core features of the website.

Is the Wild West of cookie management coming to an end?

Cookie banners still vary widely. Some categorize cookies by their purpose (advertising, analytics, personalization, security, etc.) or by the entities setting them, which can number in the dozens.

Media houses’ cookie banners have become notorious for their “legitimate interest” approach and exhaustive lists of data collectors. But what exactly does this mean?

Ad-supported entities have numerous ad spaces, widgets, and trackers on their sites, requiring the tracking of users’ activities through cookies. In these cases, media companies list all the entities, often resulting in extensive lists. Most organizations do not have such extensive cookie operations.

For municipal or average company online services or eCommerce sites, they typically use some analytics tools, a few ad platforms, and perhaps a chat functionality. The most challenging cookies are those used by ad platforms (Meta, LinkedIn, Google Ads), as you also need to explain to the user what information these cookies are storing.

However, there is a growing desire to limit cookie use for large entities. This is leading to the potential extinction of third-party cookies. For example, Chrome is likely to start restricting third-party cookies by the end of next year. The question is, will this solve the problem?

This move is likely to disproportionately impact smaller players who haven’t yet effectively established first-party cookies. Larger companies, on the other hand, have the resources to structure their websites in a way that makes adapting to this change less disruptive.

What makes a cookie banner good and lawful?

It’s clear and comprehensive

A good and lawful cookie banner should display different cookie categories (essential, analytics, preferences, marketing, etc.), the number of cookies, and a list of the cookies. CMP tools like Cookiebot, Cookie Information, and OneTrust automatically list these. When clicking on details from the cookie banner, you should be able to see all the cookies.

Each cookie should have its purpose, duration, and provider/data processor indicated. Each entity is responsible for listing and naming the cookies. If a cookie is not identified, it is very difficult to explain what it is used for. An example of this is the “unclassified” group, which is often a miscellaneous collection of different cookies. Clearly and transparently explain why these features are on the site.

It’s user-friendly

The equality of the acceptance banner buttons is essential. Declining cookies should be as easy as accepting them; if cookies can be accepted with one click, declining should also be possible with one click. Avoid leading the user in the design of the decline and accept buttons, and adhere to a visually ethical and consistent approach. For example, the accept button should not be green, and the decline button should not be red. This is not yet a requirement. The decline option should not be hidden.

The cookie banner must not have pre-checked boxes or “on” toggles for non-essential cookies. Non-essential cookies must not be enabled by default on the service or site; the user must explicitly accept them (opt-in). According to Traficom, changing consent should be as easy as giving it initially. Although this can be challenging to implement precisely, it is one reason why cookie icons often float on the edges of web pages.

User’s cookie preferences

A good and lawful cookie banner must respect the user’s level of cookie consent. If a user has not accepted marketing-related cookies, then cookies set by scripts from Facebook or LinkedIn should not be placed in their browser.

Using a ready-made cookie banner from providers like OneTrust, Cookiebot, or Cookie Information can help automate the blocking of cookies. Alternatively, you can categorize the scripts set in the site’s code yourself. The execution of these scripts can also be managed through Google Tag Manager.

It is essential to ensure that user consent preferences are properly enforced and maintained throughout their browsing experience.

Key steps to proper cookie management

Adopt a ready-made cookie banner solution

If you haven’t yet implemented a cookie banner solution, now is the perfect time to do so. Utilizing a pre-built cookie banner will simplify the process of recording cookie consents and enable you to provide proof of consent as required by Traficom. This means that if a user or any other party inquires about consent details, the user can access their unique consent ID and share it with the website owner, who can then use this ID to retrieve the consent information from their database.

Ensure compatibility with Consent Mode V2

With the introduction of Google Cookie Consent Mode V2 in March 2024, it’s essential for those running Google ads to enable this updated consent mode. If you are using one of the major cookie banner providers, your solution likely already supports this new mode. If not, it’s advisable to consult Google’s compliance listing to verify that your banner meets the requirements of the new consent mode.

Monitor the acceptance rate of the cookie banner

It’s important to track how many visitors accept the cookie banner. Usually, the acceptance rate is between 50-80% depending on the industry. If the rate is higher, your cookie banner might not meet Traficom’s guidelines and should be adjusted, which could lower the acceptance rate.

Today’s website visitors are more cautious and less likely to give permission easily. The more transparent and clear you are about your use of cookies, the more likely users are to agree to them. Keep your explanations simple and honest to build trust and improve acceptance rates.

Consider adding a cookie-less analytics solution

Given the low acceptance rate of cookies, it’s worth exploring cookie-less analytics solutions like Plausible or Matomo. These tools allow websites to track the number of visitors without relying on cookies.

While cookie-less analytics can provide basic visitor data, they may not offer the detailed insights often needed for advertising and conversion tracking. Cookies are essential for comprehensive tracking and reporting in these areas.

There are plenty of tools available for analytics, and it’s important to remember that server-side analytics solutions can also provide cookie-less data. Server-side analytics can accurately capture traffic volumes without relying on cookies.

For instance, Google Cloud Platform offers robust logging tools that allow you to create metrics using cloud platform capabilities. By monitoring logs and metrics in a cloud service environment, you can gather basic information without external or cookie-dependent tracking.

Virtualization significantly enhances disaster recovery and high availability strategies, offering robust solutions to ensure business continuity and data protection. Virtual machines (VMs) can be easily backed up and restored, making it straightforward to recover from hardware failures, data corruption, or other catastrophic events. This ease of backup and restoration is a crucial advantage over traditional physical servers, where recovery processes can be time-consuming and complex.One of the key features of virtualization platforms is live migration. Live migration allows administrators to move running VMs from one physical host to another without any downtime. This capability is invaluable for maintenance tasks, such as applying updates or performing hardware upgrades, as it ensures that critical applications and services remain available during these operations. Live migration also facilitates load balancing across multiple hosts, optimizing resource utilization and improving overall system performance.
Another important feature is failover, which ensures high availability by automatically transferring workloads to a standby VM in the event of a failure. If a physical server or a VM encounters an issue, the failover mechanism activates, seamlessly shifting the affected workloads to another VM or host. This process minimizes downtime and maintains the availability of essential services, thereby protecting against disruptions that could impact business operations.

Virtualization platforms also support advanced snapshot and cloning capabilities. Snapshots allow administrators to capture the state of a VM at a specific point in time, including its memory, disk, and configuration. These snapshots can be used to quickly revert to a previous state in case of system errors or data loss, providing a rapid recovery option. Cloning, on the other hand, enables the creation of exact replicas of VMs, which can be used for testing, development, or as part of a disaster recovery plan.

In addition, virtualization simplifies the creation of disaster recovery plans by enabling the replication of VMs to offsite locations. This geographic redundancy ensures that in the event of a site-wide disaster, such as a fire, flood, or power outage, the replicated VMs can be quickly activated in a different location. This replication can be done continuously or at scheduled intervals, depending on the business’s recovery time objectives (RTO) and recovery point objectives (RPO).

Furthermore, many virtualization platforms offer integrated disaster recovery solutions that automate the failover and failback processes. These solutions streamline the coordination of recovery activities, reducing manual intervention and accelerating recovery times. Automated disaster recovery solutions also include regular testing and validation features, ensuring that the disaster recovery plan remains effective and up-to-date.

Overall, the disaster recovery and high availability features provided by virtualization create a resilient IT infrastructure that can withstand and quickly recover from disruptions. This resilience not only protects against data loss and downtime but also instills confidence in stakeholders, customers, and partners, reinforcing the business’s reputation for reliability and stability.
Simplified management – centralized management of virtual environments simplifies administrative tasks. IT administrators can manage multiple virtual machines from a single console, streamline updates, and automate routine processes. Virtualization greatly simplifies the management of IT environments by centralizing administrative tasks and providing powerful tools for overseeing multiple virtual machines (VMs) from a single console. This centralized management approach enhances operational efficiency and reduces the complexity associated with maintaining a diverse and distributed IT infrastructure.One of the primary benefits of virtualization is the ability to manage numerous VMs from a unified interface. IT administrators can oversee the entire virtual environment, including servers, storage, and network resources, from a single management console. This holistic view allows for easier monitoring, troubleshooting, and optimization of resources, ensuring that the infrastructure runs smoothly and efficiently.
Streamlined updates are another significant advantage of virtualization.

This separation ensures that developers can work on new applications, features, and updates without risking the stability and performance of the live environment.One of the primary benefits of using virtualization for testing and development is the ability to quickly and easily create isolated environments. Developers can spin up virtual machines (VMs) that mimic the production environment, complete with the same operating systems, software, and configurations. These VMs can be used to test new code, experiment with different configurations, and troubleshoot issues without affecting the production systems. This isolation is crucial for maintaining the integrity and reliability of live applications while allowing developers the freedom to innovate and experiment.
Virtual environments also facilitate the creation of consistent and repeatable testing setups. Since VMs can be cloned and snapshots can be taken at any point, developers can easily reproduce specific states of the environment. This capability is invaluable for debugging, as it allows developers to recreate the exact conditions under which a bug occurred. Additionally, it ensures that testing is conducted under consistent conditions, leading to more reliable and accurate results.

Another significant advantage of virtualization in testing and development is the ability to simulate different environments and configurations. Developers can test applications across various operating systems, browser versions, and hardware configurations by simply creating and configuring the appropriate VMs. This level of flexibility ensures that the application will perform reliably across different user environments, enhancing compatibility and user satisfaction.

Virtualization also streamlines the deployment process. Once an application has been thoroughly tested and is ready for production, it can be deployed directly from the virtual environment. This reduces the time and complexity associated with moving applications from development to production, as the environment in which the application was developed and tested closely mirrors the production environment. This approach minimizes the risk of deployment issues and ensures a smoother transition from development to live operation.

In addition to facilitating testing and development, virtualization supports continuous integration and continuous deployment (CI/CD) practices. Virtual environments can be integrated with CI/CD pipelines, allowing automated testing and deployment processes. Each code change can trigger the creation of a new VM, where automated tests are run to validate the change. If the tests pass, the code is then deployed to a staging environment or directly to production. This automation accelerates the development cycle, reduces errors, and ensures that high-quality code is delivered consistently.

Furthermore, virtualization enhances collaboration among development teams. Multiple developers can work on different aspects of a project simultaneously in separate virtual environments, without interference or conflicts. Teams can also share VMs that contain specific configurations or setups, ensuring that everyone is working in a consistent environment. This collaborative approach improves efficiency and fosters innovation, as developers can quickly build, test, and refine their work.

Lastly, the cost-efficiency of virtualization is particularly beneficial for testing and development. Instead of investing in many physical servers for various testing scenarios, organizations can use virtual machines to replicate these environments at a fraction of the cost. This not only reduces hardware expenses but also lowers energy consumption and physical space requirements.

In summary, virtualization significantly enhances testing and development processes by providing isolated, flexible, and easily replicable environments. This capability ensures that applications are thoroughly tested and stable before going live, reduces deployment risks, supports CI/CD practices, and fosters collaboration among development teams.

Bot/bots – what is it?

Leave a reply

In its broadest definition, a bot is an autonomous program designed to perform specific tasks online. Initially created for simple functions, bots have evolved to handle more complex tasks, which can have positive and negative impacts.

What are bots in mobile fraud?

In mobile fraud, bots are automated programs that can operate on real mobile devices or servers, mimicking legitimate user actions such as ad clicks, installs, and in-app engagement. This simulation aims to deceive systems into recognizing fraudulent activities as genuine.

Another type of fraud bot is malware/mobile malware installed on a user’s device. These malware bots generate fake ad impressions, fraudulent clicks, and in-app engagement, and can even initiate fake in-app purchases, all without the user’s consent or awareness.

How to block mobile fraud bots

Closed-source SDKs – ensure your attribution provider uses closed-source SDK technology. Unlike open-source SDKs, closed-source codes are significantly harder for fraudsters to unpack and simulate, as the code is not publicly exposed for review and reverse engineering. Review all SDKs in your app, particularly attribution SDKs, and avoid those that use open-source technology to prevent security breaches.
SDK security measures – implement hashing or unique tokens to block bot activity in real time. Always use the latest SDK version from your attribution provider to benefit from the most recent security updates and defenses against known bot tactics.
- Hashing – this process transforms data into a fixed-size hash value, ensuring that sensitive information remains secure during transmission. Hashing helps to verify data integrity and detect any unauthorized changes.
- Unique tokens – these are dynamically generated, single-use tokens that verify the authenticity of each request. By using unique tokens, you can ensure that each interaction is legitimate and prevent replay attacks where bots attempt to reuse old tokens to gain unauthorized access.
- Encrypted communication – ensuring that all data transmitted between the app and the server is encrypted adds an additional layer of security, making it more difficult for bots to intercept and manipulate data.
- Certificate pinning – this technique involves associating a host with their expected X.509 certificate or public key. By doing so, it prevents man-in-the-middle attacks, ensuring that the app communicates only with trusted servers.
- Dynamic key generation – implementing dynamic keys that change with each session makes it harder for bots to crack the security measures in place, as they would need to break the encryption for each session individually.
- Rate limiting and throttling – these measures help to control the number of requests a client can make to the server within a certain time frame. By setting these limits, you can prevent bots from overwhelming your system with requests, making it easier to detect and block suspicious activity.
Behavioral analysis and anomaly detection – monitoring active user behavior and identifying patterns that deviate from normal activities can help detect bot activities. Advanced solutions like Protect360 use proprietary behavioral anomaly detection to identify and block sources generating non-human traffic automatically.
Bot signatures – fraud solutions maintain a real-time database of bot signatures, automatically blacklisting and blocking activities from known fraudulent sources. These signatures include patterns of behavior, known IP addresses, device identifiers, and other unique markers that are characteristic of bot activities. By continuously updating this database with new signatures, fraud solutions can swiftly block any traffic that matches these patterns, effectively preventing bots from causing harm.
Behavioral anomalies – identify unusual behavior patterns, such as a high density of installs that follow identical, non-human actions. Solutions like Protect360 use proprietary behavioral anomaly detection to block sources generating such traffic automatically. This detection system monitors user interactions and flags behaviors that deviate significantly from typical human patterns, such as extremely rapid clicks, uniform time intervals between actions, or consistent usage patterns across multiple devices. By analyzing these anomalies, the system can distinguish between genuine user activity and automated bot behavior, ensuring that only legitimate interactions are allowed through. This process involves sophisticated machine learning algorithms that continuously learn and adapt to new bot behaviors, providing a robust defense against evolving threats.

Application Programming Interface (API) – complex guideline about APIs (history, examples, benefits, types of APIs, API design principles, API lifecycle management and many more)

Leave a reply

API stands for Application Programming Interface, which is a software intermediary that allows two applications to communicate with each other. Every time you use an app like Facebook, send a quick message or check the weather on your phone, you’re using an API.

Developers use APIs to program apps to hide complexity, organize code, and design reusable components.

Examples of using API in daily life

When you use an app on a mobile phone, the app connects to the internet and sends data to a server. The server then reads this data, interprets it, performs the necessary actions, and sends it back to the phone. The app then interprets the data again and presents the required information to you in a readable form. That’s what an API is – everything happens through an API.

To explain this better, let’s take a familiar example.

Imagine you’re sitting at a table in a restaurant and you have a menu to choose from. The kitchen is the part of the “system” that prepares your order. However, the critical link that would communicate your order to the kitchen and deliver the food back to your table is missing. This is where the waiter or API comes in. The waiter is the messenger – or API – who receives your request or order and tells the kitchen – the system – what to do. Then the waiter delivers the answer; in this case, the food.

Here’s a real example of an API. You may be familiar with the process of searching for flights online. Just like a restaurant, you have a variety of options to choose from, including different cities, departure and return dates, and more. Imagine you book a flight on an airline’s website. You choose a departure city and date, a return city and date, cabin class, and other variables as well.

To book the flight, you interact with the airline’s website to access their database and find out if there are seats available on those dates and what the cost might be.

But what if you don’t use the airline’s website – a channel that has direct access to information? What if you’re using an online travel service like Kayak or Expedia that aggregates information from several airline databases?

In this case, the travel service communicates with the airline’s API. The API is an interface that, like your helpful waiter, can be asked by this online travel service to retrieve information from the airline’s database to book seats, baggage options, etc. The API then takes the airline’s response to your request and passes it back to the online travel service, which then displays the most up-to-date and relevant information to you.

Early beginnings

APIs, or Application Programming Interfaces, have roots dating back to the early days of computing in the 1940s and 1950s. Initially, APIs were developed as reusable software libraries and subroutines to facilitate communication within a single system. This era marked the beginning of APIs as tools for streamlining development and fostering code reuse.

Mainframe era

During the 1960s and 1970s, APIs became more structured and formalized, particularly in the mainframe era. IBM’s introduction of the System/360 family of mainframe computers included comprehensive APIs for hardware access and resource management, embedding APIs deeply into software development processes.

The rise of personal computing

The 1980s and 1990s brought personal computing into the mainstream, with operating systems like Windows and macOS. APIs became essential for developing desktop applications, with Microsoft’s Windows API (WinAPI) and Apple’s Macintosh Toolbox API providing critical functions for graphics, file systems, and user interfaces, thus enhancing the development process significantly.

The internet and web APIs

The mid-1990s saw the internet revolutionize the role of APIs. Web APIs, which allowed different web services to interact over HTTP, emerged during this period. SOAP (Simple Object Access Protocol), introduced in 1998, was among the earliest protocols enabling remote procedure calls over the internet, widely adopted for enterprise integration.

The RESTful revolution

In the early 2000s, REST (Representational State Transfer) emerged as a simpler, more flexible alternative to SOAP. Defined by Roy Fielding in his 2000 doctoral dissertation, REST principles became foundational for web API design. RESTful APIs gained popularity for their simplicity, scalability, and adherence to web standards, becoming the de facto standard for web services.

Mobile and cloud computing

The late 2000s and 2010s saw the rise of mobile and cloud computing, further expanding API importance. Mobile apps relied heavily on APIs to access cloud services, integrate with social media, and interact with backend systems. Companies like Google, Facebook, and Twitter provided robust APIs, enabling developers to build feature-rich mobile applications.

Cloud platforms like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform offered APIs for virtually all their services, from storage and computing to machine learning and analytics. This API-centric approach allowed developers to build scalable and flexible applications, leveraging the power of cloud infrastructure.

Modern API ecosystem

Today, APIs are the backbone of modern software development. The API economy has flourished, with businesses generating significant revenue by providing APIs as products. Companies like Stripe, Twilio, and Plaid are prime examples of businesses built entirely around their APIs, offering services that enable payments, communications, and financial data access, respectively.

Future trends and advancements

As technology continues to evolve, so do APIs. Future trends include the increased use of APIs in artificial intelligence, machine learning, and the Internet of Things (IoT). APIs are also becoming more secure and robust, with advancements in API security protocols and practices to protect against cyber threats.

The future of APIs will likely see greater standardization, improved developer tools, and more powerful integrations, further cementing their role as essential components of modern software development and digital transformation.

Types of APIs

APIs (Application Programming Interfaces) play a crucial role in modern software development, allowing different applications to communicate and interact with each other. They come in various forms, each serving different purposes and audiences. Understanding the different types of APIs is essential for developers and businesses to leverage their potential effectively.

Open APIs

Open APIs, also known as external or public APIs, are available to any developer who wants to use them. These APIs are designed to be easily accessible and are typically well-documented to encourage widespread use. Open APIs are a driving force behind the success of many modern web services and applications, enabling third-party developers to integrate and extend the functionalities of existing platforms.

Examples of open APIs

Google Maps API – allows developers to integrate Google Maps into their websites or applications, providing users with location-based services.
Twitter API – enables developers to access and interact with Twitter data, allowing for the creation of apps that can post tweets, read timelines, and more.

Open APIs foster innovation by allowing developers to build on top of established platforms, creating new applications and services that benefit from the robust functionalities of the original service.

Partner APIs

Partner APIs are shared externally but only with specific business partners. These APIs are not publicly available and require special access permissions. Partner APIs are designed to enable collaboration between companies, allowing them to integrate their systems and share data securely. They are often used to strengthen business relationships and create seamless experiences across different platforms.

Examples of partner APIs

Amazon Marketplace Web Service (MWS) – provides Amazon sellers with access to Amazon’s vast resources for managing inventory, orders, and reports.
Salesforce Partner APIs – allow partners to integrate their applications with Salesforce, enhancing the CRM’s functionality and providing tailored solutions for mutual customers.

Partner APIs typically include stringent security measures, such as authentication tokens and encryption, to protect sensitive data and ensure that only authorized users can access the API.

Internal APIs

Internal APIs, also known as private APIs, are used within an organization to streamline internal processes and improve system interoperability. These APIs are not exposed to external users and are designed to connect different internal systems, enabling them to work together more efficiently.

Examples of internal APIs

HR systems integration – an internal API might connect the HR system with the payroll system, ensuring that employee data is consistent and up-to-date across both platforms.
Internal microservices – in a microservices architecture, internal APIs allow different services within the same organization to communicate and function cohesively.

Internal APIs help organizations optimize their workflows, reduce redundancy, and enhance the overall efficiency of their operations by facilitating seamless data exchange between internal systems.

API design principles

REST (Representational State Transfer)

RESTful APIs follow a set of architectural principles that emphasize stateless communication, resource-based URIs, and the use of standard HTTP methods.

Stateless communication – each request from a client to a server must contain all the information needed to understand and process the request. The server does not store any state about the client session on the server side.
Resource-based URIs – resources are identified using URIs (Uniform Resource Identifiers). Each resource can be accessed through a unique URL, which represents a specific piece of data.
Standard HTTP methods – RESTful APIs utilize standard HTTP methods such as GET, POST, PUT, DELETE, and PATCH to perform operations on resources. For example, GET retrieves a resource, POST creates a new resource, PUT updates an existing resource, and DELETE removes a resource.

Advantages of REST

Scalability – statelessness and resource-based URIs make REST APIs highly scalable.
Flexibility – REST can be used over any protocol, but it is commonly used with HTTP.
Simplicity – RESTful APIs are easy to understand and implement, especially for web services.

Example of RESTful API code:

GET /users/123 Host: api.example.com

This request retrieves the user resource with the ID 123.

SOAP (Simple Object Access Protocol)

A protocol for exchanging structured information in web services, using XML for message format and relying on application layer protocols, mainly HTTP and SMTP.

XML-based messaging – SOAP uses XML to encode its messages, which allows for a highly standardized format that is both human-readable and machine-readable.
Protocol independence – SOAP can be used over various protocols such as HTTP, SMTP, TCP, and more.
WS-security – SOAP supports various security features defined in the WS-Security standard, making it suitable for applications requiring high security.

Advantages of SOAP:

Formal contracts – SOAP uses WSDL (Web Services Description Language) to describe the services, which provides a formal contract between the client and server.
Extensibility – SOAP’s protocol neutrality and language independence make it highly extensible and versatile.
Reliability – SOAP has built-in error handling and can be used for reliable messaging.

Example of SOAP code:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ex="http://example.com/"> <soapenv:Header/> <soapenv:Body> <ex:getUser> <ex:userId>123</ex:userId> </ex:getUser> </soapenv:Body> </soapenv:Envelope>
This SOAP message requests user information for the user with ID 123.

GraphQL – A query language for APIs that allows clients to request exactly the data they need, providing more flexibility compared to REST.

Client-specified queries – clients can specify the structure of the response, ensuring they receive only the data they need.
Single endpoint – unlike REST, which uses different endpoints for different resources, GraphQL uses a single endpoint to handle all queries.
Real-time data – GraphQL supports real-time data with subscriptions, allowing clients to receive live updates.

Advantages of GraphQL:

Efficiency – reduces over-fetching and under-fetching of data, as clients request exactly what they need.
Flexibility – allows for more flexible and dynamic queries compared to REST.
Strong typing – the schema defines types and relationships, which helps in validating queries and maintaining robust APIs.

Example:
query { user(id: "123") { name email } }
This query retrieves the name and email of the user with ID 123.

API lifecycle management

API lifecycle management encompasses the stages of designing, developing, testing, deploying, and maintaining APIs. Each phase requires careful planning and execution to ensure the API remains functional, secure, and efficient. Effective lifecycle management helps in delivering robust and scalable APIs, facilitating seamless integration, and ensuring ongoing performance and security.

Design

Designing APIs involves defining endpoints, request/response formats, and authentication methods. Best practices include:

Consistent naming conventions – ensure endpoint names are clear and logical.
Comprehensive documentation – provide detailed instructions and examples to guide developers.
Backward compatibility – design APIs to support future versions without breaking existing integrations.

Development

Development involves coding the API endpoints and integrating them with backend services. Common tools and frameworks include:

Express.js for Node.js – a minimal and flexible Node.js web application framework.
Flask for Python – a micro web framework for Python.
Spring Boot for Java – a framework that simplifies the creation of stand-alone, production-grade Spring-based applications.

Testing

Testing ensures that APIs function correctly and meet performance requirements. Types of tests include:

Unit tests – testing individual components.
Integration tests – verifying that different components work together.
Load tests – assessing the API’s performance under heavy load. Common tools for testing include Postman and SoapUI.

Deployment

Deployment involves making the API available to users. This phase includes:

Setting up servers – ensure reliable and scalable server infrastructure.
Configuring load balancers – distribute incoming network traffic across multiple servers.
Implementing security measures – protect the API from unauthorized access and threats.

Maintenance

Ongoing maintenance includes:

Monitoring performance – continuously track API performance to detect and resolve issues promptly.
Fixing bugs – address any issues that arise during usage.
Updating the API – implement new features, improve performance, and ensure compliance with the latest security standards.

API Testing Tools

Effective API testing is crucial for ensuring that APIs function correctly, meet performance requirements, and provide secure communication between systems. Various tools are available to help developers and testers verify the functionality, performance, and security of APIs. Here, we introduce some of the most popular API testing tools: Postman, SoapUI, and JMeter, and explain how they contribute to robust API testing processes.

Postman

Postman is a widely used tool for API development and testing. It provides an intuitive user interface that simplifies the process of sending requests to APIs and analyzing their responses.

Request building – Postman allows users to create and save HTTP requests with various methods (GET, POST, PUT, DELETE, etc.), headers, parameters, and body content.
Automation and scripting – Postman supports the creation of automated tests using JavaScript. Users can write scripts to validate responses, check performance, and ensure compliance with API specifications.
Collections and environments – Users can organize requests into collections and create environments to manage different configurations, such as development, staging, and production.
Mock servers – Postman allows the creation of mock servers to simulate API responses, enabling testing even when the real API is not available.
Collaboration – Postman provides collaboration features, allowing teams to share collections, tests, and documentation seamlessly.

SoapUI

SoapUI is a robust tool specifically designed for testing SOAP and REST web services. It offers comprehensive features for functional testing, security testing, and load testing.

Functional testing – SoapUI allows users to create and run automated functional tests for SOAP and REST APIs. It supports complex test scenarios, data-driven testing, and assertions.
Security testing – SoapUI includes features for security testing, such as SQL injection, XML bomb, and cross-site scripting (XSS) tests. It helps identify potential security vulnerabilities in APIs.
Load testing – SoapUI supports load testing to evaluate the performance and scalability of APIs under different conditions. Users can simulate multiple concurrent users and analyze the impact on API performance.
Service virtualization – SoapUI enables the creation of virtual services that mimic the behavior of real APIs. This feature is useful for testing and development when the actual API is unavailable.

JMeter

JMeter is an open-source tool primarily used for performance testing and load testing of web applications, including APIs. It provides a flexible and extensible platform for creating test plans and analyzing results.

Load testing – JMeter allows users to simulate a large number of concurrent users to test the scalability and performance of APIs. It provides detailed metrics on response times, throughput, and error rates.
Distributed testing – JMeter supports distributed testing, enabling the execution of tests across multiple machines to generate higher loads and simulate real-world scenarios.

Reporting and analysis – JMeter generates comprehensive reports with graphs and statistics, helping users analyze the performance and identify bottlenecks in the API.

These tools collectively provide a comprehensive suite for ensuring that APIs are robust, secure, and performant, enabling developers to deliver high-quality software products. But there are sure many other tools you can use for API testing, which I probably do not know. If you have a hint, you can write it in the comments. 🙂

API documentation

Proper API documentation is crucial for several reasons. It ensures that developers understand how to interact with the API, which reduces the learning curve and promotes efficient development. Well-documented APIs improve integration, minimize errors, and enhance the overall developer experience. Good documentation also supports maintenance and scalability, as it provides clear guidelines for future updates and enhancements.

Comprehensive API documentation should include:

Endpoints – a list of available endpoints with descriptions of their purposes.
Parameters – detailed information about required and optional parameters for each endpoint, including data types and constraints.
Request/Response formats – examples of request and response payloads, including headers and body content.
Authentication methods – instructions on how to authenticate requests, including tokens, keys, or other methods.
Error codes – a list of possible error codes with explanations to help developers troubleshoot issues.
Examples – practical examples of API requests and responses to demonstrate typical usage.

There are several tools available to help create and manage API documentation effectively:

Swagger (OpenAPI) – a powerful framework for API documentation that allows you to describe the structure of your APIs in a machine-readable format.
Postman – a versatile tool for testing APIs that also offers features for generating and managing documentation.
Redoc – a tool for generating interactive API documentation from OpenAPI specifications.
Slate – a static site generator for API documentation that creates clean and readable documentation.
Apiary – a comprehensive platform for designing, testing, and documenting APIs.

Why do we need an API?

Whether you’re managing existing tools or designing new ones, you can use APIs to simplify the process. The main benefits of APIs include the following:

Improved collaboration – the average enterprise uses nearly 1,200 cloud-based applications (legacy is located outside of IBM), many of which are unconnected to each other. APIs enable integration so that these platforms and applications can seamlessly communicate with each other. With this integration, businesses can automate workflows and improve collaboration in the workplace. Without APIs, many businesses would lack connectivity and suffer from information silos that threaten productivity and performance.
Easier innovation – APIs offer flexibility and allow companies to connect with new business partners, offer new services to existing markets, and ultimately gain access to new markets that can bring huge profits and drive digital transformation. For example, Stripe started as an API with just seven lines of code. Since then, the company has partnered with many of the world’s largest enterprises, diversified into lending and corporate cards, and was recently valued at $36 billion (link is outside IBM).
Monetizing data – many companies choose to offer APIs for free, at least initially, to build an audience of developers around their brand and establish relationships with potential business partners. However, if an API provides access to valuable digital assets, it can be monetized by selling access (this is known as the API economy). When AccuWeather (link is based out of IBM) launched its self-service developer portal to sell a wide range of API packages, it took just 10 months to attract 24,000 developers, sell 11,000 API keys, and build a thriving community in the process.
Security – as mentioned above, APIs create an extra layer of protection between your data and the server. Developers can further strengthen API security by using authentication tokens, signatures, and Transport Layer Security (TLS) encryption; implementing API gates to manage and authenticate traffic; and practical, efficient API management.

APIs and security

The data from your phone is never fully accessible to the server, nor is the server ever fully accessible to your phone. Instead, they communicate with each other using small data packets, sharing only what is necessary, such as takeaway food orders. You tell the restaurant what you’d like to eat, it tells you what it needs in return, and eventually, you get your food.

APIs have become so valuable that they make up a large part of many businesses’ revenue. Big companies like Google, eBay, Salesforce.com, Amazon, and Expedia are just a few of the companies that make money from their APIs. The term “API economy” refers to this API market.

But also due to the very high usage of APIs (Application Programming Interfaces) in modern life, APIs have become critical in modern software developmen. However, this increased connectivity also introduces significant security risks. Ensuring the security of APIs is paramount to protect sensitive data, maintain user trust, and comply with regulatory requirements. Here, we discuss the importance of API security and various methods to ensure it.

Authentication and authorization for API

Authentication and authorization are fundamental to API security. Authentication verifies the identity of a user or system, while authorization determines what actions they are permitted to perform.

Tokens – tokens are a common method for API authentication. They are generated after a successful login and are used to verify the identity of the user or application making the request. Tokens, such as JSON Web Tokens (JWT), provide a secure way to manage user sessions.
OAuth – OAuth is an open standard for access delegation commonly used for token-based authentication. It allows third-party services to exchange information without exposing user credentials. OAuth 2.0 is widely used for securing APIs, providing a robust framework for handling access permissions and scopes.
API keys – API keys are unique identifiers that authenticate a request to an API. While not as secure as OAuth or tokens, API keys are still used for simpler authentication scenarios. They should be used with caution and combined with other security measures to enhance protection.

Data encryption for API

Data encryption ensures that the information exchanged between clients and servers remains confidential and secure from eavesdroppers.

Transport layer security (TLS) – TLS is a cryptographic protocol designed to provide secure communication over a computer network. It encrypts the data transmitted between the client and the server, making it unreadable to anyone intercepting the communication. Implementing TLS is essential for protecting sensitive information such as user credentials and personal data.
End-to-end encryption – in scenarios requiring heightened security, end-to-end encryption can be employed. This ensures that data is encrypted on the sender’s side and only decrypted on the receiver’s side, preventing intermediaries from accessing the content.

Rate limiting for API

Rate limiting is a technique used to control the amount of incoming and outgoing traffic to and from a server. It helps prevent abuse, such as denial-of-service (DoS) attacks and ensures fair usage among users.

Request quotas – setting quotas for the number of requests a client can make within a specified time frame helps mitigate the risk of DoS attacks. Exceeding the quota results in the request being denied, protecting the API from being overwhelmed by too many requests.
Throttling – throttling limits the rate at which a client can make requests. If a client exceeds the rate limit, subsequent requests are either delayed or rejected. Throttling is useful for managing the load on the server and maintaining performance.
IP whitelisting – restricting access to APIs based on IP addresses ensures that only trusted clients can make requests. This method can effectively prevent unauthorized access and reduce the risk of abuse from unknown sources.

Additional security measures for API

Beyond authentication, authorization, data encryption, and rate limiting, several other security practices can enhance API security.

Input validation – validating and sanitizing all inputs to the API helps prevent common attacks such as SQL injection and cross-site scripting (XSS).
Logging and monitoring – implementing robust logging and monitoring mechanisms allows for the detection and investigation of suspicious activities. Monitoring API usage patterns can help identify and mitigate potential security threats.
Security audits and penetration testing – regular security audits and penetration testing can uncover vulnerabilities in the API. These proactive measures enable developers to address security flaws before they can be exploited by malicious actors.
Versioning and deprecation – managing API versions ensures that outdated and potentially insecure versions are phased out systematically. Deprecation policies guide users to migrate to newer, more secure versions of the API.

Modern APIs

Over the years, the term “API” has often referred to any kind of generic interface for connecting to an application. Recently, however, modern APIs have acquired some characteristics that make them extremely valuable and useful:

Modern APIs follow standards (typically HTTP and REST) that are developer-friendly, easily accessible, and widely understood.
They are treated as products rather than code. They are intended to be consumed by a specific audience (e.g. mobile developers), documented, and versioned so that users can have certain expectations about their maintenance and lifecycle.
Because they are much more standardized, they have a much stronger discipline for security and governance, as well as being monitored and managed for performance and scope.
Like any other software produced, modern APIs have their own software development life cycle (SDLC) that includes design, testing, build, maintenance, and versioning.
Modern APIs are also well-documented for consumption and versioning.

Future trends in APIs

The future of APIs promises to be dynamic and transformative, driven by advancements in AI, machine learning, and IoT. As technology evolves, APIs are expected to play an even more crucial role in enabling seamless integration, enhancing functionalities, and fostering innovation. Here are some key trends to watch:
