What are Web Vitals?

Web Vitals - sometimes referred to as Core Web Vitals - are Google's way of assessing user experience on websites and providing quantifiable metrics to indicate the score. They compose of a selection of specific factors that are deemed most valuable for users. In simpler terms, Web Vitals contribute to your overall page experience score, which influences your search ranking.  

The following three factors are part of the Core Web Vitals, along with the metrics used to measure them:

  • LCP - Largest Contentful Paint measures Loading performance
  • FID - First Input Delay measures Interactivity
  • CLS - Cumulative Layout Shift measures Visual Stability

With LCP, Google measures the page loading times as perceived by users. Effectively, it measures how long it takes for the largest content element on a page to become visible to a user, which can be impacted by slow scripts and server response times

FID looks at the responsiveness of pages in relation to user input. When a user first interacts with a page, there is a period where the browser has to respond to this action. FID measures this period, and the shorter it is, the better. 

Finally, CLS is a measurement of page stability. It's rather complex, but it counts how many times the different elements of a page such as fonts and images move around during loading. A page with minimal shifts will be better than one with lots. 

Why are Web Vitals important?

Web Vitals matter because they are the objective method that Google use to assess the quality of a page. This measurement is then used to help determine the rankings of pages in the Search Results. Google wants to promote high quality content that give users what they need so if your Web Vitals scores are good, it’s a sign of quality and the page has a better chance of being placed higher.

Google has been using Web Vitals as a ranking factor since June 2021 and they will continue to stay in place for the foreseeable future. It’s also expected that additional metrics will be added to the Web Vitals collection. In essence, if you want your site to perform well in search engines, you need to pay attention to the Core Web Vitals now and in the future.
