What is Core Web Vitals

It is an initiative (another) that has launched our Google to have controlled the user experience, and, consequently, the loading speed of the analyzed web.

The goal is always to improve the quality with which users browse the Internet.

Google already has experience in launching tools to boost the speed of websites, such as PageSpeed Insights, or LightHouse.

In conclusion, they are the Main Vitals that a website should have. Or another way of saying it, 3 more metrics to assess the good health of a page.

There are three, and we see them below:

First Input Delay


This first vital, that we are discussing, is related to the user’s interaction with the website.

It’s basically about the time it takes for the site to click a button and the page responds to them and performs the action.

Many times the cursor is left with a round thinking when we give it somewhere, and that frustrates us a lot as web surfers.

We will have a good FID if it is less than 0.1 seconds.

Largest Contentful Paint


This vital is what it takes for a content item to load. From the start until it is just loaded and can be fully displayed.

We must ensure that the loading time of the elements is the minimum

This element that you must load can be text, or media element such as image or video, which are the ones that take the longest.

We will have a good LCP if it is less than 2 and a half seconds.

Cumulative Layout Shift


CLS deals with visual stability. And it’s not like the previous ones, it doesn’t measure time.

Hasn’t it ever happened to you that while you’re loading a website, things are changing places? And do you inadvertently hit a button that you didn’t want to hit, because it had moved?

This is the CLS.

And it is measured by analyzing the frequency with which changes occur. Every time an element changes places, you are given points, and a good CLS will be if it has less than 0.1 points.

As a summary, we leave you a table so that you can keep in mind how you should have the website, and how the user experience will be optimal:

FID>0.1 seconds
LCP>2.5 seconds
CLS>0.1 points
