Core web vitals, as announced by Google in 2020, are a set of factors, or rather metrics, that evaluate the page experience of a website. They are therefore important to create a good user experience in the real world.

As we know, Google’s goal is always to display the most relevant results in a search and guarantee the best possible user experience in terms of navigation and speed, which is why in 2021 web core vitals will officially become a ranking factor.

 

core web vitals overview

Which web vitals are considered core

There are several parameters to measure the quality of a user’s navigation experience on a website, but those considered essential by Google are three:

  1. Largest Contentful Paint (LCP)
  2. First Input Delay (FID)
  3. Cumulative Layout Shift (CLS)

Core web vitals

LCP (Largest Contentful Paint) is how long it takes a page to load from the point of view of an actual user.

In other words: it’s the time from clicking on a link to seeing the majority of the content on-screen.

 

FID (First Input Delay) is the time it takes for a user to actually interact with your page.

Examples of interactions include:

  • Choosing an option from a menu
  • Clicking on a link in the site’s navigation
  • Entering your email into a field
  • Opening up “accordion text” on mobile devices

 

CLS (Cumulative Layout Shift) is how stable a page is as it loads (aka “visual stability”).

In other words; if elements on your page move around as the page loads, then you’ve got a high CLS. This is considered a bad thing in Google’s eyes.

 

How to measure core web vitals

To date, the performance of a site can be measured using:

  • PageSpeed Insights
  • Lighthouse
  • Search Console
  • Chrome UX Report
  • Chrome DevTools
  • Web Vitals Extension
