Let’s discuss each web vitals in detail.

Largest Contentful Paint (LCP)


LCP is defined as the time required to view the first colorful content/text to which a user can interact. LCP measures the page loading performance of the webpage. The unit of LCP is seconds.

Most of the top websites have the LCP below 1 sec however, the LCP below 2.5 sec gives good user experience. You can check your LCP metrics using Google Page Speed Insights. If it is above 2.5 sec, please optimize the page to bring down. Lesser the time better the user experience.

First Input Delay (FID)


FID is defined as the time taken by the user to interact with your web page. The interactions could be anything from below:

  • Choosing an option from a menu
  • Clicking on a link in the site’s navigation
  • Entering your email into a field

FID measures the power of the interactivity of the web page. The unit of FID is seconds. The FID is useful when the webpage is interactive and it is of no concern if it is related to blog pages.

The FID below 100 milliseconds states that the user can spot and the content is fair enough to take action. If it is above 100 milliseconds, please optimize the page to bring it down. Lesser the time better the user’s interactivity performance.

Cumulative Layout Shift (CLS)


CLS is defined as the core web vital that defines the stability of the web page. The CLS ensures page stability by checking if all the webpage elements are in place.

This could be confirmed if the user clicks on the right element of the web pages appear at the right place or not. The ideal CLS should be between 0 to 0.1
