Performance
- LCP· Largest Contentful Paint
LCP is the time from a navigation start to the moment the largest text or image on the viewport finishes rendering — Google's main visual-load metric.
- CLS· Cumulative Layout Shift
CLS scores the visual stability of a page — how much content jumps around as it loads.
- INP· Interaction to Next Paint
INP measures the responsiveness of a page — the time from a user input (click, tap, key) to the next visual update the browser commits.
- Core Web Vitals· CWV
Core Web Vitals are Google's three real-user metrics for page experience: LCP (load), CLS (stability), and INP (responsiveness).
