Top 5 WordPress Speed Optimization Plugins – Free and Paid

pattern 21

You have probably heard about the importance of speed on websites. But what exactly does it mean? And how do you optimize your website for speed?

The speed of a website depends on many factors, including running on a good server and most importantly, choosing a plugin with performance features such as caching and CSS/JS optimization.

And for today’s standard, Speed isn’t the only factor for SEO algorithms, with the introduction by Google of the Core Web Vitals. Page Experience becomes as much as important as having a website loading fast.

Take a look below for a list of top plugins to improve your website Pagespeed and also fix your Core Web Vitals, the new algorithm from Google. Many of these plugins can be used together to maximize results(check compatibility).



Perfmatters may be discouraging to use due to its advanced features, but its interface lets beginners remove unnecessary code from running to improve Pagespeed and Core Web Vitals.

Perfmatters “Script Manager” lists all your scripts and allows you to remove them from loading by device type, location, group of users, or using a regex formula.

You can access Perfmatters documentation to make sure what effect each feature will have, and how to fix any issues, if encountered. Perfmatters also offers a “Testing Mode”, which safely previews features before applying them to the live website.

One of the features of Perfmatters is database optimization, offering scheduled automatic database optimization. Perfmatters also have many features focused on Woocommerce. Other Perfmatters features:

Flyingpress is a caching plugin, developed by the creator of the Flying Script plugin, and website 

Flyingpress main difference from other caching plugins may be their newly released features such as Prioritize Resources that directly improve the LCP(largest contentful paint) Core Web Vitals. LCP is one metric where WordPress falls apart from other technologies.

FlyingPress also offers another tool to optimize LCP, such as lazyload, with the option to exclude in the interface above-the-fold images. Most lazyload plugins improperly lazyload above-the-fold images, compromising the LCP metric.

Another newly and powerful released feature is Cloudflare APO compatibility. Competitors may lack this feature.

FlyingPress has also all the features of caching-performance plugins such as Remove Unused CSS, Delay JS or Defer, and Database Optimization. Other main features:

  • Critical CSS
  • Minify
  • Optimize Google Fonts: Self-host, combine and preload Google Fonts.
  • Reduce CLS feature: Add missing width and height attributes to images.

FlyingPress recently fixed a broken access control vulnerability in its plugin.

FlyingPress offers a CDN addon powered by BunnyCDN starting at $3/month for 100GB/bandwidth usage.
