Measure LCP, CLS, and INP. Understand what's slowing your page down and get specific fixes to pass Core Web Vitals.
Run this focused check to generate a complete PDF audit. The report includes the topic below plus SEO, performance, security, accessibility, DNS, and domain health signals.
Core Web Vitals are Google's metrics for measuring user experience: Largest Contentful Paint (LCP) measures loading speed, Cumulative Layout Shift (CLS) measures visual stability, and Interaction to Next Paint (INP) measures responsiveness.
Since 2021, Core Web Vitals are a Google ranking factor. Sites that pass all three metrics get a ranking boost in search results. Poor scores can hurt your visibility and user engagement.
A good LCP score is under 2.5 seconds. Scores between 2.5-4 seconds need improvement, and over 4 seconds is poor.
Set explicit dimensions on images and videos, avoid inserting content above existing content, and use CSS transform for animations instead of properties that trigger layout changes.
Google replaced First Input Delay (FID) with Interaction to Next Paint (INP) in March 2024. INP measures overall responsiveness, not just the first interaction.
