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.

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.
