Core Web Vitals

in short

Core Web Vitals are Google's metrics for page loading speed, interactivity and visual stability.

Core Web Vitals are three key metrics: LCP (main content load), INP (responsiveness) and CLS (layout stability).

How it works

Google collects real Chrome user data. Good thresholds are LCP under 2.5s, INP under 200ms, CLS under 0.1.

Why it matters

  • A ranking factor
  • Slow pages lose conversions
  • Especially important on mobile

How Accendix handles it

We optimize images, fonts, JS and server response so every metric is in the green.
