8+ Best WordPress Plugins To Help You Optimize For Google Core Web Vitals – 2021

Sure, you’ve heard of user experience before? Could you tell us how good the UX of your website is? To answer these questions, Google has established a series of metrics called Core Web Vitals and they could affect your rankings on Google.

Our websites become slower for hosting, CSS, large image, javascript and several issues. With some WordPress plugins, you can resolve the issues and make your website faster. Here I have presented the best WordPress plugins to help you optimize for google core web vitals. These plugins target the page loading speed, response and stability of your blog or website.

Let’s introduce with the Core Web Vitals

Core Web Vitals consist of three metrics to measure UX on a web page. Let’s look at each of these metrics:

LCP or Largest Contentful Paint

This indicator measures how long it takes until the user sees the web site’s main content in their browser. In other words, the first appearance of the content (FCP or First Content Paint) is no longer so important.

LCP have these credentials:

  • Good: less than 2.5 seconds.
  • Medium: up to 4 seconds. (Need improvements)
  • Poor: more than 4 seconds.

FID or First Input Delay

The FID dealings with the user’s interaction with the page. To establish how good or bad the time-lapse is between user interaction and browser reaction, Google states that:

  • Less than 0.1 seconds is good.
  • Up to 0.3 seconds means you need to improve.
  • More than 0.3 seconds is poor.

CLS or Cumulative Layout Shift

This metric assesses a web page’s visual stability and is perhaps the most difficult to understand if you are not very familiar with web development.

Many pages load some of the content in the background to ensure a low load time. However, sometimes it happens that these loading processes are not well coordinated and the elements change their location as the content is loaded. This impairs the user’s browsing experience.

Therefore, this Core Web Vitals indicator measures the frequency and magnitude with which these changes occur. And it does it this way:

  • Good: less than 0.1.
  • Needs improvement: up to 0.25.
  • Poor: more than 0.25.
