What are Google's Core Web Vitals?

Core Web Vitals is a mix of the major metrics used by Google to rank pages. They check the site for usability, loading speed, visual stability, and information relevance. All Core Web Vitals work to ensure that the user gets the best and the most relevant results when searching on the Internet.

Core Web Vitals metrics

Previously, Core Web Vitals were considered recommendations. Today they are an important Ranking Factor. 

  1.  Largest Contentful Paint (LCS)

LCS measures how long it takes for your page to load after the first user`s click.

This element can be text, photo, video thumbnails, or any other element. This only covers items that are displayed on the screen without scrolling.

  • Good - less than 2.5 sec

  • Need to be improved - between 2.5 sec and 4.0 sec

  • Bad - more than 4.0 sec

  • Good - less than 100 milliseconds

  • Need to be improved - between 100 milliseconds and 300 milliseconds

  • Bad - more than 300 milliseconds

  • Good - less than 0.1

  • Need to be improved - between 0.1 and 0.25

  • No intrusive interstitials

Are Core Web Vitals important?

Core Web Vitals are not just important, they are super important —  your site depends on them.

But if your site has poor performance in these metrics, then Google will punish you with a low ranking.

If you have problems with Core Web Vitals, then web developers can fix all errors.
