Google PageSpeed Grade does not Improve

In most cases, WP Rocket will improve your PageSpeed grade. The extent to which it improves depends on the baseline performance of your site: the hosting, plugins you’re using, content you’ve added etc.

How can I improve Core Web Vitals?

Please see our guides:

Find your site’s baseline performance

Disable WP Rocket and run a PageSpeed test to see what your baseline scores are. 

Alternatively, you can also run a test bypassing WP Rocket, by adding ?nowprocket to the URL, to find the baseline.

Then, reactivate WP Rocket and adjust the options as described below.

How WP Rocket can improve your score

Here are the specific WP Rocket features that will directly impact your score:

Page caching

Caching is enabled automatically (unless your webhost is handling it) and will increase the overall score and Core Web Vitals. It also directly improves server response time.

Mobile caching

This option is enabled by default. It ensures your mobile site is cached and all optimizations are applied there.

Delay JavaScript Execution

This is a very powerful feature which can help improve the following recommendations, and therefore have a significant impact on your score:

  • Google Fonts are automatically optimized

Minify CSS 

Minify JavaScript

Prefetch DNS requests

Check how if your score has improved

After activating and configuring the above options, run another PageSpeed test to see how it’s improved. Consult the detailed guides provided above to find out more.

How to optimize further

There will likely be some remaining recommendations, which cannot be fixed completely with WP Rocket.  We’ve covered the most common ones in the list below:

All of our guides on PageSpeed recommendations can be found here.

Please see our guide: How to Improve Your Mobile PageSpeed Score

How long does it take to see the improvements?

WP Rocket's speed improvements take place immediately. The report should change in real time, after you've enabled/disabled the optimization features. 

As a note, the Optimize CSS delivery and Remove Unused CSS features will show a notice to let you know you when they've been completed and are successfully applied to your site. 

If you don't see changes right away, please check this guide, or please contact our support team.

My score isn’t high enough, can you optimize my site for me?

We don’t provide an optimization service but our support is here to help if there are specific issues using our features. Optimization is a complex task that will require some work on your part, too. In some cases you may need the help of a developer. In that case, we recommend Codeable.

Regardless of the score, WP Rocket makes the actual loading time of your page faster, improving the experience for your visitors. To get another perspective of the speed, you could use a tool like Pingom to measure the load time.
