What are Web Vitals?

Through both internal studies and industry research, users show they prefer sites with a great page experience. In recent years, Search has added a variety of user experience criteria, such as how quickly pages load and mobile-friendliness, as factors for ranking results. Earlier this month, the Chrome team announced Core Web Vitals, a set of metrics related to speed, responsiveness and visual stability, to help site owners measure user experience on the web.
~Evaluating page experience for a better web

Google's announcement linked above describes a change in its search algorithm to evaluate and prioritize page experience. In this announcement Google introduces a new set of metrics to help developers measure and analyze a user-centric page experience called "Web Vitals". According to web.dev, Core Web Vitals are the subset of Web Vitals that apply to all web pages, and should be measured by all site owners. Each of the Core Web Vitals represents a distinct facet of the user experience, is measurable in the field, and reflects the real-world experience of a critical user-centric outcome.

In summary, we can utilize Google projects like Lighthouse and Web Vitals to not only improve web page experience but also improve SEO.
