Read on to learn more about Core Web Vitals and how they can impact your SEO.
What is Core Web Vitals?
Web Vitals is what we know as the compendium of metrics that allow us to know specific data about the user experience on websites. In this sense, Core Web overseas chinese in worldwide phone number data Vitals is part of these measurement units created by Google with the purpose of facilitating the analysis of your website.

How it works
Also known by their Spanish translation as Principal Vital Signals, Core Web Vitals are applicable to all portals. At the moment, Google has only proposed 3 metrics for 2020 and 2021. However, each of these serves to identify different aspects of users and their relationship with your website. Below, we discuss the 3 Core Web Vitals measures.
Largest Contentful Paint (LCP)
The first unit of measurement in Core Web Vital is used to analyze the loading speed of your website . In other words, it determines how long it takes before the main content of the website is visible to a user in the browser.
Normally, the load is distributed starting with the text and ending with images or videos, and is measured in seconds. This is certainly an important point, since a waiting time that is too long is not beneficial for your positioning.
Google gives the following ratings for this metric:
Good: less than 2.5 seconds.
Needs improvement: up to 4 seconds.
Poor: more than 4 seconds.
First Input Delay (FID)
When a page loads, users will typically want to interact with it by filling out a form, zooming in on images, or clicking on a link. First Input Delay measures how well these processes are carried out.
This second Core Vitals metric analyses the response time of your website after the user makes their first click. Interaction is the first contact between a website and the user, hence the importance of measuring FID to optimise SEO and positioning.
Google provides the following ratings for this metric:
Good: less than 0.1 seconds.
Needs improvement : up to 0.3 seconds.
Poor: more than 0.3 seconds.
Cumulative Layout Shift (CLS)
Finally, we find the last of the 3 Core Web Vitals metrics. CLS is primarily responsible for measuring the visual stability of a web page. Nowadays, more complex websites load parts of their content in the background to reduce their loading times for the user.
In some cases, these loading processes may not be coordinated, which can cause the page content to fail while the user is already trying to read it. Consequently, these changes can cause frustration in users, which is why it is considered a relevant element when it comes to user experience.
Google provides the following ratings for this metric:
Good: less than 0.1 seconds.
Needs improvement: up to 2.5 seconds.
Poor: more than 0.25 seconds.
How does it affect SEO?
It is expected that by next year 2021, Google will announce the launch of the Core Web Vitals as important aspects for positioning . Therefore, if you are not taking them into account or not implementing them in your SEO strategy, you will probably not appear in the top positions in the search engine.
Google usually makes an announcement at least 6 months before its implementation in the algorithm. This gives website owners and developers enough time to prepare. For now, what we can recommend is to start taking this into account, in advance, but in 6 months or more.
