About this tool
The Core Web Vitals tool analyzes your page performance using Google's official metrics: Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS).

Frequently asked questions
Core Web Vitals are Google's metrics for measuring user experience: LCP (loading speed), INP (interactivity), and CLS (visual stability). They're direct ranking factors.
Good scores are: LCP under 2.5 seconds, INP under 200 milliseconds, and CLS under 0.1. Scores above these thresholds need improvement.
