Web Vitals: Metrics & Tooling
Web Vitals is a set of ±10 metrics compiled by Google’s internal team to assess and quantify web page performance. The value of this particular set of metrics, and the reason it’s popular with frontend developers, is that all of these metrics have a direct impact on the user experience of page visitors. This means that if we improve these metrics, we are objectively improving the experience of users visiting our site.
