Core Web Vitals
Definition
Core Web Vitals are a set of three metrics (LCP, CLS, INP) defined by Google that measure real-world page load performance, visual stability, and interactivity.
Plain English
Three scores that tell you whether your page feels fast, stable, and responsive to users.
Why it matters
- They influence search ranking signals.
- Poor scores correlate with higher bounce rates.
- They're measured from real user data (CrUX) not just lab tests.
