Find the best settings for your site

This tutorial shows you how to enable WP Rocket's optimizations safely, fix common layout issues if they come up, and tweak settings if you notice any negative effect on your server resources.

Note: Every site has a different theme, a different set of plugins, different content, and uses a different hosting setup. The best settings and exclusions will vary from site to site.

Activate the additional optimizations

After you've enabled WP Rocket, the automatic features and default settings will be applied to the website.

However, enabling the additional optimizations is key and will help you get the most out of WP Rocket. This section walks you through this process:

1. Go to the File Optimization tab and enable the available features:
   • Remove Unused CSS
   • Load JavaScript deferred
   • Delay JavaScript execution
     
2. In the Media tab, enable all the available features too:
   • LazyLoad
   • Add missing image dimensions
   • Preload fonts
   • Self-host Google Fonts.
3. Go to Preload and enable Preload links.

Best practices for configuration

Follow these tips as you enable features and adjust settings.

• You don’t need to clear the cache after enabling each feature.
• Enable features one at a time to make it easier to identify the cause of any issues.
• After each change, check key pages to make sure everything still looks and works as expected.
• Keep in mind that WP Rocket has a few asynchronous optimizations that can take some time to be applied. 
• Pay attention to the recommended features in the sidebar, these come from Rocket Insights. 

Troubleshoot layout issues

Sometimes performance optimizations can cause issues with the site layout.

Please refer to the My site is broken article to learn how to identify the problematic feature and how to fix these problems without disabling WP Rocket entirely. 

Troubleshoot server load issues

In some cases, the processing of some optimizations can have a heavy impact on the server.

Check the Configuration for large websites article, where you'll find some guidelines to balance WP Rocket's optimizations with the available server resources.

Other features and tabs

WP Rocket includes more features across the other tabs:

• Use Rocket Insights to monitor the performance of your key pages.
• You can use the features in the Advanced Rules tab for fine-tuning WP Rocket
• There are options in the Database and Heartbeat tabs that help optimize other parts of your WordPress site.
• You can find and configure some integrations in the CDN and Add-ons tabs.
