Last updated on May 22, 2022 | By

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?

You can start with the basics of running on a good server and later choose a good performance plugin with features such as caching and CSS and JS optimization.

To keep things easy, below is a list of hand-picked plugins to optimize or fix any of the issues from Core Web Vitals – the new algorithm from Google – and Pagespeed which is Google’s speed test tool. Consider plugins that are compatible with your current plugin stack, verifying compatibility.

Cloudflare currently offers Automatic Platform Optimizations (APO) for 5$/mo, and it caches the HTML of your WordPress website. This is possible due to Cloudflare Workers that cache dynamic content.

According to Cloudflare, their Automatic Platform Optimization plugin optimized their client’s Web Vitals and Core Web Vitals metrics:

“Automatic Platform Optimization consistently demonstrated better aggregate performance among sites we analyzed in TTFB, First Paint, FCP, and LCP metrics. Even more impressive are improvements on both desktop and phone form factors.”
