Core Web Vitals are a common set of signals critical to all web experiences. The Core Web Vitals metrics are First Input Delay (FID), Largest Contentful Paint (LCP), and Cumulative Layout Shift (CLS), with their respective thresholds. A page passes the Core Web Vitals assessment if the 75th percentiles of all three metrics are Good. Otherwise, the page does not pass the assessment.
