Core Web Vitals
Core Web Vitals Three values Google uses to rate how a page feels: how fast the main content appears (LCP), how fast it reacts to clicks (INP) and whether content jumps while loading (CLS). -
Lab and field data
Lab and field data Lab data comes from a test measurement. Field data are values from real visitors that Google collects in Chrome – they only exist for pages with enough visitors.
