Core Web Vitals & PageSpeed Booster


Core Web Vitals (CWV) is the new ranking factor

Google announced that “Core Web Vitals” are going to be a significant ranking signal for websites. 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.


  • 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.

After I installed the plugin, I am unable to upload new images. 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.

i would say, it more good for a free plugin, it worked well in optimiszing my woocommerce website speed. Also there was a specific error for my desktop score with a QUESTION ❓ mark in the pagespeed score. I contacted their support and would say they have done their best with their time and knowledge and sorted the issue. My pagespeed score has rocketed af this. I am happy I don't need a premium plugin anymore for website speed. Thanks guys
