Core Web Vitals is a set of user experience performance metrics focused on loading speed, interactivity, and visual stability.
Example of Core Web Vitals
Example: A service page may have strong copy but poor Core Web Vitals if the hero image is too large, scripts block interaction, or elements shift as reviews load. Improving LCP, INP, and CLS helps both users and search performance.
Why Core Web Vitals matters
It matters because technical issues can prevent great content from being discovered, rendered, indexed, or trusted. Strong technical foundations protect rankings during redesigns, migrations, content expansion, and platform changes.
