What are Core Web Vitals?

Core Web Vitals (CWV) are set of metrics defined by Google that measure the interactivity and visual stability of your webpage. The three important metrics include largest contentful paint (LCP), which measures loading speed, first input delay (FID), which measures page interactivity, and Cumulative layout shift (CLS), which measures visual stability. According to these metrics, the better a page performs, the better the experience it provides.
