WP Rocket Detector

How can you check if a website uses WP Rocket?

Detecting if a website uses WP Rocket, a popular caching plugin for WordPress, involves looking for specific markers in the website’s source code and behavior.

Here’s a step-by-step guide on how to do it:

1. Open the Page Source: Right-click on the webpage and select “View Page Source” or press Ctrl+U (Windows) or Cmd+Option+U (Mac) to open the page’s source code.
2. Check for WP Rocket Footer Marker: Scroll to the bottom of the page source code to look for a comment indicating WP Rocket. You might see a line that says: <!-- Cached by WP Rocket -->
3. Look for WP Rocket-Specific File Paths: Use Ctrl+F (Windows) or Cmd+F (Mac) to open the search function and look for the following path:
   • wp-content/plugins/wp-rocket/: This path indicates that the WP Rocket plugin is installed on the website.
4. Check for Page Load Speed: WP Rocket improves website load speed. Use an online speed test tool (like Google PageSpeed Insights) to analyze the site. If the speeds are significantly fast, it could be using WP Rocket or a similar optimization tool.
5. Inspect Network Requests: Open the browser developer tools (usually by pressing F12 or right-clicking and selecting “Inspect”). Go to the “Network” tab and reload the page. Look for requests that reference wp-rocket in the file names, such as wp-rocket.min.js.
6. Check for Rocket Loader: If the website uses WP Rocket, it might include a lazy loading feature for images and iframes. Look for the data-lazy-src attribute in image tags. Example: <img class="lazyload" data-lazy-src="image-url.jpg" >.
7. Look for Prefetched Links: WP Rocket can add prefetching capabilities to improve navigation speed. Check the page source for <link rel="prefetch"> tags that could be added by WP Rocket.
