What is Core Web Vitals?
Core Web Vitals (CWV)
Definition, formula, India benchmarks, and the operator-grade nuance behind it.
Core Web Vitals are Google's set of three metrics measuring real-world user experience: LCP (Largest Contentful Paint), INP (Interaction to Next Paint, replacing FID), and CLS (Cumulative Layout Shift). CWV is a Google ranking factor — passing all three lifts rankings.
Core Web Vitals = LCP + INP + CLS thresholds.
All three must hit 'Good' for ranking benefit.
Measured via Chrome UX Report (CrUX) on real users, not synthetic.
Core Web Vitals = three metrics: LCP (loading), INP (interactivity), CLS (visual stability). All measured by Google Chrome User Experience Report.
CWV Pass = LCP < 2.5s AND INP < 200ms AND CLS < 0.1The operator's read on Core Web Vitals
CWV thresholds: LCP < 2.5s = Good, < 4s = Needs Improvement, > 4s = Poor. INP < 200ms = Good, < 500ms = NI, > 500ms = Poor. CLS < 0.1 = Good, < 0.25 = NI, > 0.25 = Poor. Google measures via real-user data (CrUX), not Lighthouse synthetic. Indian sites often fail LCP due to slow mobile networks; mitigate via Cloudflare R2 cache + image optimization + critical-CSS inlining.
India 2026 benchmarks — Core Web Vitals
