Web Vitals was an initiative by Google that provides a guide to indicators that help content creators and web pages to achieve a better experience for viewers when they enter their site. Although it can be difficult to keep up with all the tools and metrics out there today, the goal of Web Vitals is nothing more than to simplify and help
these websites to focus on the bottom line; the Core Web Vitals.
But now yes. What are the Core Web Vitals? It is the set of various Web Vitals that must be applied and measured on each web page, they represent the different stages of the buyer’s journey on the page and whose main objective is to balance the load of a website, your website, in terms of speed and accessibility to create a more enjoyable experience and ensure that those who need the content
that you think take you into account in the first place.
In 2020 they focused on three main aspects; content loading (LCP), visual stability (CLS) and interactivity with the page (FID). So, and more briefly, in order to understand the Core Web Vitals we must become familiar with the metrics of our page based on these three aspects.
