Your ad is only as good as the page it runs on.

Compare the sites in your media plan before the budget is spent.

While you build your media plan, see the ad density and page speed of the sites in it. Using data from real Chrome users, PubRank compares these sites with similar publishers in your market quickly and shows which ones you should reconsider. Next to the core metrics in your media plan, such as impressions, reach and CPM, add a score for each site’s ad experience.

  • Real Chrome data, not a crawler
  • Ranked against your own market
  • Your Excel plan, as it is

Score 5 sites from your plan, free

No sign-up, no card.

Two impressions at the same CPM are not the same impression.

Ad clutter

On some pages one ad has the screen to itself; on others it shares it with many more. The rate card rarely shows the difference.

Heavy pages

Ads that eat processor time and data slow the page down. Slow pages can hurt the reader’s experience and the conditions your ad loads in.

Now measurable

Chrome now reports how many ads real visitors see, how much of the screen they cover and what they cost the device. PubRank turns these new, experimental metrics into a score you can plan with.

How does it work?

  1. Upload your plan

    Excel or CSV, as your team already writes it. PubRank finds the website, device, category and budget columns in the languages of all 9 markets, and tells you about every line it could not use. The file is read in your browser; your plan is not shared with other customers and is never added to the comparison data.

  2. Every publisher is scored

    From 0 to 100, weighing how much advertising the page carries against how the page performs for real visitors. Each site is ranked against comparable publishers in your market: on the same device, and in the same category when it has enough of them.

  3. Move the money

    See the sites with the strongest and the weakest ad experience, the budget-weighted score of the whole plan, and your CPMs set against the PubRank score. Export it, or share the report with your client.

What does Chrome report, and what does it look like?

The underlying measurements come from the Chrome UX Report: what real visitors to these sites experienced over the last 28 days, on their own phones and computers. PubRank calculates the scores and comparison indicators from them. Nothing is crawled or simulated.

How much advertising the page carries

Ad density

The share of the screen covered by ads while someone scrolls. The higher it is, the less of the screen is left for the article — and for your ad.

Ad count

How many ads are on screen at the same time. It shows how much your ad shares the screen with other ads.

Ad weight

The processor time and the data the ads use during a visit. Heavy ads drain the battery, spend the visitor’s data and slow the page down.

How the page performs for the visitor

Largest Contentful Paint (LCP)

How long the main content takes to appear. Google calls 2.5 seconds or less good, and more than 4 seconds poor.

Interaction to Next Paint (INP)

How quickly the page answers a tap or a click. Good is 200 ms or less, poor is more than 500 ms.

Cumulative Layout Shift (CLS)

How much the page jumps while it loads — the ad that drops in and pushes the text down. Good is 0.1 or less, poor is more than 0.25.

The drawings show what each measure means, not any publisher’s figures. The ad measures are new and still experimental in Chrome; the three Core Web Vitals are Google’s own, with the thresholds Google publishes.

What does a report tell you?

Each line of the plan gets a score and, when it is low, the reason a visitor would notice.

Which report is for whom?

The same scores make five reports. You can look at an example of each.

9 markets, each on its own benchmark

A German plan is compared with German publishers, a Polish plan with Polish ones. Each market has its own index and is sold on its own.

Built on data you can check

Real visits

The Chrome UX Report: anonymous measurements from real Chrome users, at the 75th percentile over 28 days.

Every score explained

Each score shows the metrics and the comparison behind it. Sites without enough data are marked as such, never scored as zero.

Clear about its limits

PubRank does not measure viewability, invalid traffic or brand safety, and it is not a Google rating. It covers websites, not social platforms, YouTube, apps or CTV.

Contains data from the Chrome UX Report by Google, licensed under CC BY 4.0. The data has been aggregated and scored for this report. Not affiliated with or endorsed by Google.

What do the measurements cover?

Each market is compared with its own publishers. The measurements include every visit to those sites that CrUX records, from inside the country and from abroad: CrUX has no country filter.

Chrome’s share of page views in a country is not the share of users the measurements cover. It only shows how much weight Chrome carries there: about three page views in four in Türkiye, about half in the United Kingdom, and in Norway Chrome is not even first.

What the data can see

Measured

  • Chrome on Windows, macOS, ChromeOS and Linux
  • Chrome on Android

Not measured

  • Chrome on iPhone and iPad — Chrome on iOS reports nothing
  • Safari, Edge, Firefox, Opera and every other browser
  • Apps, social platforms, YouTube and CTV

Within Chrome, only users who turned on usage statistics and history sync, without a sync passphrase, send these measurements. Google does not publish what share of users that is, in any country — so nobody, including us, can tell you that number.

Browser shares: StatCounter, August 2026. StatCounter counts page views on the sites in its network, not people, and revises a month for 45 days after publishing.

Questions

Where does the data come from?

From the Chrome UX Report (CrUX), which Google publishes under the CC BY 4.0 licence: anonymous, aggregated measurements from Chrome users who share usage statistics. PubRank scores and compares them; it does not crawl sites.

Does PubRank measure my campaign?

No. PubRank measures the pages: how heavy the advertising is and how the page behaves for real visitors, over the latest 28 days. How many of your impressions were seen, or by whom, is measured by ad verification tools.

Can a publisher pay for a better score?

No. Every site is scored the same way from the same public data. Buying a Site Report or Annual Site Monitor, or verifying a site, never changes its score or its rank.

Is this a Google rating?

No. PubRank is independent. The scores are ours, relative to the publishers in the same market, and Google does not endorse them.

What happens to sites with little traffic?

When Chrome has too little data for a site, the report says so. The site is never given a score of zero, and it does not pull your average down.

Do I have to reformat my plan?

No. Upload the Excel or CSV you already have. PubRank finds the header row and the columns in English, Turkish, German, French, Italian, Polish, Dutch and the Nordic languages, and you can correct its choices before running the analysis.

What does the free snapshot include?

Up to 5 websites against one market: the average score, your strongest sites and the ones with the lowest experience, each with the main reason. No sign-up.
