Web Performance Benchmark
Compare your site's Core Web Vitals with your competitors. Real data from the Chrome User Experience Report (CrUX).
No CrUX data is available for this site. This can happen if:
- • Traffic volume is too low for Google to collect data
- • The homepage is set to noindex or blocked by robots.txt
- • The domain is too new (less than 28 days of data)
- • The site is a Single Page App (SPA) without Server-Side Rendering
Need to measure your performance?
I can set up custom web performance monitoring, independent of CrUX data.

Need to improve your scores?
A web performance audit identifies high-impact optimizations for your Core Web Vitals.
Why benchmark web performance?
Core Web Vitals are the metrics Google uses to evaluate your site's user experience. A slow site loses visitors: every additional second of load time reduces the conversion rate by 7% on average.
This benchmark uses real data from the Chrome User Experience Report (CrUX) – the same data Google uses for SEO ranking. These are not synthetic tests: they are real measurements from your actual users.
Comparing your site with competitors helps identify your performance positioning. A faster site than its competitors benefits from a direct SEO advantage and better conversion rates.
How to interpret the results?
Each metric is measured at the 75th percentile (p75): 75% of your users have an experience at least as good as the displayed value.
The overall score is calculated from the three Core Web Vitals: LCP (40%), INP (30%) and CLS (30%). A score of 100 means all metrics are in the green zone.
Official Google thresholds
| Metric | Good | Needs work | Poor |
|---|---|---|---|
| LCP – Largest Contentful Paint | ≤ 2.5s | ≤ 4.0s | > 4.0s |
| INP – Interaction to Next Paint | ≤ 200ms | ≤ 500ms | > 500ms |
| CLS – Cumulative Layout Shift | ≤ 0.1 | ≤ 0.25 | > 0.25 |
| TTFB – Time to First Byte | ≤ 800ms | ≤ 1800ms | > 1800ms |
| FCP – First Contentful Paint | ≤ 1.8s | ≤ 3.0s | > 3.0s |
LCP measures the loading time of the largest visible element. INP measures responsiveness to user interactions. CLS quantifies layout shifts during loading. TTFB measures server response time. FCP indicates when the first content appears.
Frequently asked questions
Where does the data come from?
The data comes from the Chrome User Experience Report (CrUX), a public Google dataset collected from Chrome users who have opted into sharing usage statistics. Only Chrome on desktop and Android is covered.
Why doesn't my site have data?
CrUX requires a minimum traffic volume to collect data. Sites with few Chrome visitors do not have data available.
How often is the data updated?
Google updates CrUX data weekly on a rolling 28-day window. The results therefore reflect your site's recent performance.
What is the difference with Lighthouse or PageSpeed Insights?
Lighthouse and PageSpeed Insights run synthetic tests from a server. CrUX measures the real experience of your visitors. Both are complementary: Lighthouse diagnoses, CrUX validates.
