How to Check If a Website Was Built with WordPress

Sometimes you need to know if a website runs on WordPress. This could be for security reasons, understanding how it performs, or planning your site. Finding this information is not always obvious. However, you can uncover if WordPress powers a site with a few simple steps.

Analyzing Source Code

Checking the source code of a website offers clues about its CMS. Here’s how you can do it:

  1. Search for ‘wp-content’: Open the site’s source code by right-clicking on the page and selecting “View Page Source” or pressing Ctrl+U. Look for the term “wp-content.” This folder stores assets like themes and plugins specific to WordPress. If you spot any files or directories named “wp-content,” chances are the site uses WordPress.
  2. Meta Tags for Themes or Plugins: In the source code, look for meta tags that mention WordPress themes or plugins. These tags often include the name of a theme or plugin, providing a direct indication of WordPress usage. For instance, you might see a line like <meta name="generator" content="WordPress 5.8">.
  3. Presence of ‘WordPress’: Sometimes the word “WordPress” appears directly in the code. This can happen when plugins or themes explicitly mention it. Seeing this term suggests a strong likelihood that the site is built with WordPress.

Testing Common WordPress URLs

Testing specific URLs can also reveal if a site uses WordPress:

  1. Accessing /wp-admin/: This URL leads to the admin login page of WordPress sites. Type /wp-admin/ at the end of the website’s main URL. If it redirects to a login page, the site probably uses WordPress. However, some sites hide or rename this page for security, so this method isn’t foolproof.
  2. Other URLs like wp-login.php and wp-trackback.php: Try appending /wp-login.php or /wp-trackback.php to the website’s URL. These are standard URLs in WordPress. If you reach a log in page or another recognizable page, it indicates WordPress usage.

These steps provide a solid approach to determining if a website is WordPress-based, offering insights into its structure and management.

Utilizing Online Tools to Detect Websites Built with WordPress

Online tools offer a straightforward way to identify if a website is running on WordPress. These resources scan and analyze the underlying technology of a site, providing detailed reports on the content management system (CMS) in use.

BuiltWith and Similar Tools

BuiltWith is one of the most popular tools for this task. It examines the technologies a website uses, including CMS, analytics, and hosting details. To use it, simply enter the website’s URL, and BuiltWith will generate a comprehensive report, indicating if WordPress is present.

Other tools like Wappalyzer and CMS Detect also provide similar services. These platforms function by scanning the website for recognizable patterns and scripts that are unique to different CMS platforms, including WordPress.

How These Tools Work

These tools operate by:

  • Scanning Source Code: They look for specific signatures in the source code. For WordPress, they search for elements like "wp-content" the presence of WordPress-specific cookies and scripts.
  • Analyzing Response Headers: They review the HTTP headers sent by the server. If the server reveals WordPress-specific headers, the tools can identify the CMS.
  • Checking for Common URLs: They verify the existence of WordPress-specific URLs like /wp-admin/ or /wp-login.php. If these URLs are accessible, the tools report WordPress usage.

Accuracy and Limitations

While these tools are generally reliable, they have limitations:

  • Accuracy: Most tools precisely detect WordPress when the site doesn’t hide its CMS. However, if a site owner uses plugins or techniques to obscure WordPress indicators, detection becomes challenging.
  • Limitations: Some sites disable common WordPress URLs or hide meta tags, making it harder for tools to confirm the CMS. Also, tools might show false positives if a site mimics WordPress patterns without actually using it.

In summary, online tools like BuiltWith offer a convenient way to see if a site is made on WordPress, although they may not always be 100% accurate.

Using Browser Extensions for Quick Detection

Browser extensions provide a fast way to determine if a site uses WordPress. These tools work directly in your browser, analyzing web pages as you visit them.

Chrome Sniffer and Other Extensions

How to Install and Use Chrome Sniffer:

  1. Visit the Chrome Web Store: Search for “Library Sniffer” in the store.
  2. Add to Chrome: Click “Add to Chrome” and then “Add Extension” in the pop-up.
  3. Use the Extension: Once installed, navigate to a website. The Chrome Sniffer icon changes to indicate the CMS. If it shows the WordPress logo, the site is likely running on WordPress.

Other Extensions:

  • Wappalyzer: This extension offers more detailed insights. It identifies not only the CMS but also analytics tools, e-commerce platforms, and more. Wappalyzer uses similar methods to detect WordPress, such as searching for unique scripts and cookies.
  • Library Sniffer: This extension identifies libraries and frameworks used on websites. It is not CMS-specific but can highlight WordPress-related libraries.

How Extensions Detect CMS

Extensions identify CMS by:

  • Analyzing Page Elements: They scan for specific HTML elements and attributes unique to WordPress, such as class names or IDs often used in WordPress themes.
  • Inspecting Scripts: Extensions look for JavaScript or CSS files loading from locations like “wp-content/plugins,” a typical WordPress directory.
  • Checking Cookies: Some extensions detect cookies set by WordPress, which can be a clear indication of the CMS in use.

By using browser extensions, you gain a quick and effective method to see if a site is made on WordPress, enhancing your ability to gather information on the fly.
