Sample site report
A publisher’s Site Report, on a sample site
Below is the screen a publisher sees in a Site Report. The site is illustrative and every figure comes from synthetic demo data: this is not a real publisher or real Chrome measurements. A real report shows your own site, on real Chrome UX Report data.
How to use it to improve your site
See where you rank
Your site’s place in its category and in the market, on phone and desktop separately.
Find what pulls the score down
Every metric is compared with similar publishers: see which of ad density, ad weight or page experience weighs most on your score.
Follow the effect of a change
Run the report again after a fix. Chrome data covers the last 28 days, so the effect shows up gradually over about four weeks, not at once.

How to read this reportWhat the scores and metrics mean
Each publisher is scored on two things people notice when they visit a site: how much advertising gets in their way (ad load) and how fast and stable the page is (page experience). The data comes from the Chrome UX Report — anonymous measurements from real Chrome users over the last 28 days. Hover or tap the i icons in the report for the same explanations.
Scores
0–100, higher is better.
- Overall score
- The site’s overall score, from 0 to 100. With Phone + Desktop it blends both devices by how much of the site’s Chrome traffic comes from each. Higher is better.
- Publisher experience
- The combined score on one device, from ad load and page experience. 0–100, higher is better.
- Ad load
- How heavy the advertising is for visitors compared with similar publishers: how many ads are on screen, how much of the screen they cover, and how much processing and data they use. 0–100; a higher score means a lighter ad load than peers.
- Page experience
- How fast and stable the page feels to real visitors, based on Google’s Core Web Vitals (LCP, INP, CLS). 0–100, higher is better.
- Score colours
- Green is 75 or more, amber 50–74, red below 50. The bands are relative to the publishers we compare against; they are not official Google thresholds.
Ad metrics
Measured by Chrome for real visitors. Lower is better.
- Ad count
- The average number of ads visible on screen at the same time while people scroll the page. Lower is better.
- Ad density
- The average share of the visible screen covered by ads while people scroll the page. Lower is better.
- Ad weight – CPU
- The total processor time used by ads during a visit. High values slow the page down and drain phone batteries. Lower is better.
- Ad weight – Network
- The total data downloaded by ads during a visit. High values slow loading and use mobile data. Lower is better.
Page experience metrics
Lower is better.
- Core Web Vitals (CWV)
- Google’s three standard measures of page experience — LCP, INP and CLS — each with published “good” and “poor” thresholds.
- Largest Contentful Paint (LCP)
- How long it takes for the main content of the page to appear. Good: 2.5 s or less. Poor: more than 4 s.
- Interaction to Next Paint (INP)
- How quickly the page responds when someone taps, clicks or types. Good: 200 ms or less. Poor: more than 500 ms.
- Cumulative Layout Shift (CLS)
- How much the content jumps around while the page loads, for example when an ad pushes text down. Good: 0.1 or less. Poor: more than 0.25.
Reading the tables
- p75
- The value that 75% of real Chrome visits over the last 28 days matched or beat. It describes a typical-to-worse visit rather than the best case.
- Score
- The metric converted to 0–100. Ad metrics: rank among the compared publishers (100 = lightest). Core Web Vitals: position against Google’s thresholds (80 at “good”, 50 at “poor”).
- Compared with
- Which publishers an ad metric was ranked against: the same category when at least 20 other publishers are available, otherwise all publishers on that device. n is the number compared.
- Weekly trend
- The p75 value week by week. Ad metrics only have history since Chrome began reporting them. A rising line means the metric is getting worse.
- Status
- Scored: enough data on every device. Partial: one device or page experience is missing. Insufficient CrUX data: too little real Chrome traffic, or no ads detected. Benchmark too small: not enough comparable publishers yet.
- Worsening
- At least one ad metric is 20% or more worse than four weeks earlier.
