Core Web Vitals
Google’s three speed-and-stability metrics: LCP, INP, and CLS.
What it means
Core Web Vitals are Google’s field-measured metrics for page experience: Largest Contentful Paint (how fast the main content appears), Interaction to Next Paint (how fast the page responds to taps), and Cumulative Layout Shift (how stable the layout is).
How it affects your SEO
They are a confirmed ranking factor — a small but real tiebreaker among otherwise comparable pages. More importantly, fast, stable pages convert better and reduce bounce, which feeds back into engagement signals Google can observe.
Core Web Vitals — frequently asked questions
Are Core Web Vitals a major ranking factor?
They are a confirmed but small ranking factor — a tiebreaker between otherwise comparable pages. The bigger SEO benefit is that fast, stable pages convert better and reduce bounce.
What is a good Core Web Vitals score?
Aim for LCP under 2.5 seconds, INP under 200 milliseconds, and CLS under 0.1. Passing all three in field data puts your page in the “good” range Google measures.
