Core Web Vitals

A set of Google metrics measuring page loading speed, interactivity, and visual stability.

Why It Matters

Core Web Vitals are a confirmed Google ranking factor that directly impacts user experience.

How It Works

Google measures three metrics: Largest Contentful Paint (loading), Interaction to Next Paint (interactivity), and Cumulative Layout Shift (visual stability). Pages passing all three thresholds get a ranking boost.

Real-World Example

Improving LCP from 4.5s to 2.0s moves a page from "Poor" to "Good" and correlates with a 15% traffic increase.

Common Mistakes

!

Optimizing lab data but ignoring real-user field data

!

Fixing one metric while degrading another
