We don’t go too deep into these metrics, but the general message is that they are all calculated within the performance score of Google Lighthouse. Lighthouse is a tool that Google created to measure the performance of a website. It gives a score to 4 categories: performance, accessibility, best practices, and SEO. The Core Web Vitals are included in this first category: the performance score. You can try it out yourself at web.dev/measure (Google’s online interface for Lighthouse). It runs on the servers of Google.
