In fact, Core Web Vitals or the page experience signal is going to become a requirement for a page to appear in Google’s Top Stories. ### Features * **Flush Cache**: Using this option you can choose on which events ( WordPress Update,Switching Theme,Post/Page Deletion ) you want to clear website cache. * **Auto Clear Cache**: Clear you website on regular intervals , this helps you to keep your website cache updated. * **Webp images**: If images are slowing down your website, then converting them to WebP format can improve your page load speed test scores. * **Lazy Load**: Lazy loading allows your website to only load images when a user scrolls down to a specific image, which reduces website load time and improves website performance. * **Minification**: If you are trying to achieve 100/100 score on Google Pagespeed or GTMetrix tool, then minifying CSS and JavaScript will significantly improve your score. * **Remove Unused CSS**:Unused CSS is any CSS code added by your WordPress theme or plugins that you don’t really need. Removing this CSS code improves WordPress performance and user experience. * **Google Fonts Optimizations**: You may start noticing external resources like fonts affecting Google PageSpeed + load times. This is where loading Google Fonts locally comes into play. * **Delay JavaScript Execution**:You can delay JavaScript based on user interaction. This can be a great way to speed up the paint of the page for Google PageSpeed when something isn’t needed right away. Especially heavy third-party scripts like Google Adsense, Google Analytics etc. * **Cache**: Caching is one of the most important and easiest ways to speed up WordPress! it reduces the amount of work required to generate a page view. As a result, your web pages load much faster, directly from cache. ### Support We try our best to provide support on WordPress.org forums.

This plugin is so bad and evil that even when you deactivate and delete it from your site, the cwv-image will remain affecting your site images. I have to use another plugin to remove the cwv-image to stop the 404 evil this plugin did to my site. The plugin has shown us evidence that not all free plugins have genuine intention. Some are fraudulent with serious criminal motive to cause harm to your site unknown to you if not vigilant. We have spent thousands of dollars to purchase and subscribe plugins which we believe is more better than some completely free lifetime plugin who may have some fraudulent intentions. This plugin has made us to remove several completely free plugins from our site. One of our purchased plugins is the one currently helping us to redirect the 404 image links created by this plugin to the rightful permanent links. ![](https://secure.gravatar.com/avatar/b946b4f64bc78605ae3c1fafec3b1ccd80d19602ee58f5d4c34992cf40f7c36d? s=60&d=retro&r=g) ### 󠀁[This is not what you’re looking for](https://wordpress.org/support/topic/this-is-not-what-youre-looking-for/)󠁿 [alangrah](https://profiles.wordpress.org/alangrah/) June 9, 2024 1 reply I don't normally leave reviews but this thing trashed the site.

The result on Google Page speed Insights was good and my mobile score matched my desktop score at 99% so top marks. However my mobile menu was no longer useable and there is no way the drop down would work. I am using WP Rocket and Cloudflare also. I disabled both of these plugins and cleared my cache and browser and still the same problem. I then turned of the cache, disabled all CSS features in your plugin and no change. My mobile menu still did ot work. Finally a deleted your plugin and the menu was active once again. I would love for your plugin to work for me and I would also even pay a small yearly fee if it did but at the moment its not good enough. Sad ![](https://secure.gravatar.com/avatar/96ffe916a1eed5b20bb8cf97243a695caaee49acbd51ce40733aa29b064b1d26? s=60&d=retro&r=g) ### 󠀁[significant issues with my blog posts](https://wordpress.org/support/topic/significant-issues-with-my-blog-posts/)󠁿 [doruhalip](https://profiles.wordpress.org/doruhalip/) January 11, 2024 1 reply This plugin caused significant issues with my blog posts that were previously performing well in Google search rankings, resulting in a noticeable drop.

This is the error I get: The server cannot process the image. This can happen if the server is busy or does not have enough resources to complete the task. Uploading a smaller image may help. Suggested maximum size is 2560 pixels. I tried to switch the Image Optimization to Manual. It does not help either.
