SEO: Why are Core Web Vitals so important?

Google announced that in 2021 SEO will be affected! How? It will be by three more measures to know how good a web page is. These Web Core Vitals are Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift. But what are they?

After making the announcement, Google only told developers that this new feature would begin operations around May 2021. Even though there is no specific date, the company has worked a lot to teach us how these Web Core Vitals will work.

Largest Contentful Paint (LCP). How does this affect SEO?

With this Google is looking to improve user experience and get rid of contents that take too long to load. Now SEO will be affected by the Largest Contentful Paint, a metric that measures how much time the page’s biggest element takes to become visible.

Google determined that a good LCP should be fully rendered in less than 2.5 seconds. More than 4 seconds will be considered a poor Largest Contentful Paint. As explained by the company, this may be caused for slow server response times, render-blocking JavaScript and CSS, Slow Resource load times, and client-side rendering.

First Input Delay (FID)

This Web Core Vital will measure how responsive your web is. Its goal is to evaluate the time that passes from when the user first interacts with the page to when the browser responds to that action.

Google has said that a good FID should take less than 100ms (milliseconds). More than 300ms is considered weak. The advice in this case for our SEO analysts is to optimize how JavaScript executes on your web page, as it is the principal cause for a slow browser response.

Cumulative Layout Shift (CLS)

CLS will measure how many unexpected changes occur while the page is loading. In other words, this is when a visible element changes its position between rendered frames annoying the user. This metric will work as a score in which each unexpected change will give a previously established number of points.

If the page has fully loaded and has a score of 0.1 (or less), it will be considered a good CLS. If it is above 0.25, it’s poor and needs to be improved. Luckily, Google has a whole detailed post where explains how each unexpected change is scored and how you can avoid all of them.
