Core Web Vitals: Google’s new SEO indicators

by Mohd Shahrukh June 07, 2021

In a few weeks, Google will begin to consider new indicators for its ranking: “Core Web Vitals” or essential web signals. These aim to reflect the user experience better when the search engine analyzes and indexes your website. Even if they won’t revolutionize ranking overnight, it is crucial to make sure your site aligns with the “Core Web Vitals” indicators now. We explain them to you in this article!

What are Google’s “Core Web Vitals”?

Presented by Google as indicators to offer the best possible user experience on the web, the “Core Web Vitals” will measure three vital elements of your website’s performance. The “Largest Contentful Paint” (LCP) will measure the loading speed of your pages, the “First Input Delay” (FID) will calculate the responsiveness of your site, and the “Cu mulative Layout Shift” (CLS) will take visual stability into account.


The “Largest Contenful Paint” ( LCP )

The loading speed of your website has always been a crucial part of good SEO. However, Google believes it is necessary to refocus the indicator on the user’s load time perception. Therefore, the “Largest Contentful Paint” will no longer measure the total loading time of your site but the time required for the main content to be loaded. A good LCP score will be below 2.5 seconds.

The “First Input Delay” (FID)

Google’s second “Core Web Vitals” aims to measure the responsiveness of your site. Indeed, there is nothing more frustrating for a user to click on a link and not respond to the website! The FID will measure the delay between the moment when an interaction is carried out by the user and when the website reacts to this interaction. An adequate FID should be less than 100 milliseconds.

What is First Input Delay (FID)?

First Input Delay (FID) measures page responsiveness to user input. FID measures how long it takes for a user’s first interaction with a page to respond. When a user first interacts with a page (i.e., when they click a link or tap on a button) until the browser responds to that interaction.

This is essential as even the slightest delays can be frustrating.

The “Cumulative Layout Shift” (CLS)

When a visitor travels a Room E website web, it may be that the elements alter the layout while the site seems to be responsible. Consequently, the user can see his position on the page move or, worse, click r on a link that he would not click! The causes of such a layout change can be multiple: an image changing dimensions, a typeface modifying the size of the characters of the texts displayed, or even an external advertisement.

With s are “Core Web Vitals ,” Google wants to reduce this type of friction for the end-user. Therefore, the “Cumulative Layout Shift” will measure how visually stable your website is, considering the number of times such an event occurs. It will be necessary to have an aggregate score below 0.1 for Google to consider your CLS as good.

How to comply with Core Web Vitals?

A website conforming to Google’s Core Web Vitals is, above all, an optimized website. To do this, it is recommended to use a reliable CMS like WordPress so that you can make the necessary changes quickly.


Using Google Search Console, you have access to a report of experience users detailing the results of your website. You will then be able to act on problematic pages by optimizing them.

In short…

Although the “Core Web Vitals” will only be taken into account in a few weeks, Google already provides all the tools necessary to optimize your website now. In future articles, we’ll explain each indicator in more detail. In the meantime, do not hesitate to contact one of our experts to help you with this task!
