What is Core Web Vitals?

Core Web Vitals, Google identifies user-centric metrics as important signals for determining how good the user experience is on a website. In 2024, Core Web Vitals will be an important ranking factor as part of Google’s larger effort to improve the web user experience.

In order to maintain a successful website, website owners must attend to three Core Web Vitals:

Largest Contentful Paint (LCP): This measures the loading performance of a website, specifically the time it takes for the largest content element on the screen to load. Ideally, LCP should be less than 2.5 seconds.

First Input Delay (FID): This measures the interactivity of a website, specifically the time it takes for a user to be able to interact with the page after clicking a link or button. Ideally, FID should be less than 100 milliseconds.

Cumulative Layout Shift (CLS): This measures the visual stability of a website, specifically the number of unexpected layout shifts that occur while the page is loading. Ideally, CLS should be less than 0.1.
