What This Check Looks At

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.

Why It Matters

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.

Checks Included In The PDF

Largest Contentful Paint (LCP) - target under 2.5s

Cumulative Layout Shift (CLS) - target under 0.1

Interaction to Next Paint (INP) - target under 200ms

Speed Index

Frequently Asked Questions

What is a good LCP score?

A good LCP score is under 2.5 seconds. Scores between 2.5-4 seconds need improvement, and over 4 seconds is poor.

How do I fix CLS issues?

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.

What replaced FID with INP?

Google replaced First Input Delay (FID) with Interaction to Next Paint (INP) in March 2024. INP measures overall responsiveness, not just the first interaction.
