What is the Core Web Vitals?

The Core Web Vitals update is a change Google is making to its ranking algorithm that focuses on user experience. It takes into account a measurement of how long it takes a web page to load from the moment a visitor attempts to access it to when the last piece of content has loaded.

Why are they so important?

Known as the Core Web Vitals update, it is to improve user-experience as well as help reduce your digital carbon footprint.

Websites that provide a positive user-experience with increasing page speed and clean short code will rank higher than those who do not provide a great user-experience.

Here is a breakdown of the 3 Core Web Vitals:

  • (LCP) Largest Contentful Paint: The speed in which large content areas on a page load (eg full-width images, videos, large blocks of text). These content areas should load within 2.5 seconds of loading the page
  • (FID) First Input Delay: The speed in which a user is able to interact with a page (eg fill in an input form, click on a button). A user should be able to interact with a page within 100 milliseconds of loading the page
  • (CLS) Cumulative Layout Shift: The measurement of how much the layout of a page shifts as it loads (eg text being pushed down or a button moving just as you go to click on it). A page should shift no more than 0.1.

Google expects all the above metrics to be met at their minimum standard to benefit from the upcoming algorithm update rolling out May 2021.

Rollout - June 2021
