Rocket Insights

The Rocket Insights Add-on uses GTmetrix to show and monitor the performance of the key pages of your website.

This feature can be found in the Rocket Insights tab:

In the Performance Summary section, you will find:

• The performance grade and the Core Web Vitals of the tracked pages.
• Options to add and remove pages, re-test the pages, and see the reports.

With Rocket Insights, you can monitor the performance of up to 10 URLs, and run unlimited tests.

Additionally, in the Settings section:

• The Performance Monitoring setting will help you automatically test the monitored pages in a daily, weekly or monthly basis.

Moreover, Rocket Insights uses the WP Rocket sidebar to display:

• The Rocket Insights Score, which shows average scores of the tracked pages.
• The Recommendations, which advise you to enable the features that should improve your website according to the test results.

Rocket Insights view in post lists

In addition to the above, you can also find a Rocket Insights view inside the WordPress posts/pages list page.

From there, and according to your Rocket Insights plan, you can also add, re-test and see the reports of cacheable pages/post types.

How to disable Rocket Insights view in the posts list

You can use the Rocket Insights Recommendations toggle in your WP Rocket account page to disable the Rocket Insights post column view on all websites that use your license.

Note that it could take up to 24 hours before this setting is applied to the sites.

If you prefer, you can disable the visualization of this column from the Screen Options section.

Alternatively, you can completely remove the Rocket Insights column (so that this is not visible either in the Screen Options), using this code snippet:

// Remove Rocket Insights column from posts/pages list page

add_filter('manage_posts_columns', 'custom_post_columns');

function custom_post_columns($columns) {
unset($columns["rocket_insights"]); // the column you want to remove
return $columns;
}

You can add this in the functions.php of your child theme, a custom functionality plugin or code snippet manager, as shown in this article: Add code snippets. 

Troubleshoot

If the Rocket Insights tests are not completed and the grade is not displayed after a long time, or, you see an error instead of the grade, or, the Recommendations are not loading, please make sure your site meets the following requirements:

• Be publically accessible.
• Meet the same Remove Unused CSS's basic requirements.
• GTmetrix requirements:
  • Have a valid and trusted SSL certificate, as per this.
  • Allow requests from these locations/IPs.

If the Rocket Insights tab is not present, it's probably because:

• Your site uses a staging domain from this list.

Technical notes

• The GTmetrix tests will use the iPhone 13/13 Pro/14/16e device and the Unthrottled Connection parameter.
• The test location will be the closest physical location automatically detected with geolocation. If the geolocation fails, the default location will be Seattle, WA, USA.
• More information about the reports can be found in the GTmetrix documentation.
• If your site uses mandatory cookies, the test will run on the non-cached version of the page, and the results will not be correct. For those sites, Rocket Insights is unfortunately not a good tool to use. It's recommended to use the GTmetrix tool directly, as cookies and other parameters can be customized.
