Core Web Vitals are Google's measures of real user experience on a page. They cover how fast the main content loads, how quickly the page responds and whether it jumps around.
The three measures
- Loading: how fast the largest content appears
- Interactivity: how quickly the page reacts to taps
- Visual stability: whether elements shift while loading
Why they matter
A fast stable page keeps visitors and supports rankings. It also helps ad conversion.
How to improve
Compress images, use modern formats, reduce heavy scripts, host on a fast server and set sizes for images and ads.
How to check
Use PageSpeed Insights and the Core Web Vitals report in Search Console.
Frequently asked questions
