What are Core Web Vitals?

Core web vitals are the metrics that search engines use to measure the user experience of the website. It focuses on how soon the website or the content on the website loads, how interactive the site is, and how soon the page layout loads.

There are three main types of core web vitals:

  • LCP or Largest Contentful Paint tracks the loading performance of the site - specifically the image or the text that appears on the screen.

  • FID or the First Input Display, tracks the time taken for the user to respond after the user interacts on the screen by clicking a CTA.

  • CLS or the Cumulative Layout Shift, tracks the time taken for the page elements to load on the screen.

The core web vitals are important to improve the user experience on the website and they help the page to rank higher on the search engine.
