Overview
The Web Vitals page shows the p75 (75th percentile) value for each metric — this is the threshold Google uses for search ranking signals.Metrics displayed
Each metric shows:- Current p75 value — The 75th percentile score
- Score badge — Color-coded: green (Good), orange (Needs Improvement), red (Poor)
- Trend — How the metric has changed over time
Thresholds
| Metric | Good | Needs Improvement | Poor |
|---|---|---|---|
| LCP | ≤ 2.5s | ≤ 4.0s | > 4.0s |
| FID | ≤ 100ms | ≤ 300ms | > 300ms |
| CLS | ≤ 0.1 | ≤ 0.25 | > 0.25 |
| FCP | ≤ 1.8s | ≤ 3.0s | > 3.0s |
| TTFB | ≤ 800ms | ≤ 1.8s | > 1.8s |
Using the data
- LCP too high? — Optimize images, fonts, and server response time
- CLS too high? — Add width/height to images, avoid dynamic content injection
- FID too high? — Reduce JavaScript execution time, break up long tasks
- FCP too high? — Optimize critical rendering path, reduce render-blocking resources
- TTFB too high? — Improve server response time, use a CDN
