Summary
Analyze Web Vitals score and metrics.
Check the performance of web site:
- Largest Contentful Paint (LCP);
- First Input Delay (FID);
- Cumulative Layout Shift (CLS).
Web Vitals is a recent Google initiative to provide unified guidelines for measuring essential quality elements to deliver an exceptional user experience on websites.
Google's Web Vitals initiative aims to simplify the landscape and help web developers focus on the metrics that matter most, the Core Web Vitals.
With Web Vitals, Google is specifying a set of 3 distinct performance metrics to make up their "Core Web Vitals" that they use to make a judgement on whether or not your website has a good user experience. Google is also specifying a few leading indicator metrics in the Web Vitals specification that are not classified as "core."
Google has been promoting the importance of website speed since their inception, so no surprise here. However, this is the first time they explicitly identify the specific performance metrics that are used to drive their search rankings.
