Let us move further and know all about core web vitals in detail.

What Are Core Web Vitals?

Core Web Vitals are measurements of how well your website is performing, it all depends on the overall user experience, how long your website takes to load, the amount of time it takes to solve the questions for which users visited it etc.

Do you Know? Among the millions of websites running on the internet only 4% manage to follow all the core web vitals, this ensures that if you follow it there is a very high chance that your website will rank high on google. Now, you must be curious to know what all those criteria are.

Core Web Vitals are of three types–

1. Largest Contentful Paint (LCP)

This measures how much loading time it takes for all the content to appear on a web page when you enter it. It is the score of the loading time of the largest images and videos.

It is considered good when the time is <= 2.5 seconds. It needs improvement when it is <= 4 seconds and it is considered poor when the time required is >=4 seconds.

2. First Input Delay (FIP)

This measures the quickness of your website, it says how responsive and interactive it is. It is the time of execution of action which you are seeking for. For example, when you click a button there, you buy something from the website etc.

It is considered good when the time is <=100 milliseconds. It needs improvement when it is <= 300 milliseconds and it is considered poor when the time required is >=300 milliseconds.

3. Cumulative Layout Shift (CLS)

Cumulative layout Shifts are the measure of summation of the total number of shifts in the layout. The layout means the change in frame of a website, for example when you open the homepage of youtube and then click some video frame changes.

Overall CLS keeps an eye on the visual stability of a website. The score depends on the number of layout shifts. A zero means no shifts in layouts.

 It is considered good when the time is <=0.1second. It needs improvement when it is <= 0.25 seconds and it is considered poor when the time required is >=0.25 seconds.
