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.
Open-web publisher quality
Your ad is only as good as the page it runs on.
DAX scores every open-web publisher in your media plan on ad clutter and page experience, from real Chrome visits, and ranks it against its own market. Find the pages where your ad competes for attention on a slow, crowded screen, before the budget goes out.
- Real Chrome data, not a crawler
- Ranked against your own market
- Your Excel plan, as it is

No sign-up, no card.
Two impressions at the same CPM are not the same impression.
Heavy pages
Ads that eat processor time and data slow the page down. Readers leave before your ad has even loaded.
Now measurable
Chrome now reports how many ads real visitors see, how much of the screen they cover and what they cost the device. DAX turns these new, experimental metrics into a score you can plan with.
How it works
Upload your plan
Excel or CSV, as your team already writes it. DAX finds the website, device, category and budget columns in the languages of all eight markets, and tells you about every line it could not use.
Every publisher is scored
From 0 to 100: 60% ad load, 40% page experience. Ad load is ranked against comparable publishers in your market: on the same device, and in the same category when it has enough of them.
Move the money
See the cleanest and the most cluttered sites, the budget-weighted score of the whole plan and quality-adjusted CPMs. Export it, or share the report with your client.
What a report tells you
Each line of the plan gets a score and, when it is low, the reason a visitor would notice.

Which side are you on?
The same scores, read three ways: by the agency that builds the plan, the advertiser who pays for it, and the publisher who is in it.

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
DAX 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.
Pricing
A Site Report on one site is €220; following it for a year with Site Monitor is €1,100. A one-off Media Plan Audit is €990 for one plan in one market. The annual subscription is €6,990 a year for one market, with unlimited analyses. Prices exclude VAT.

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. DAX scores and compares them; it does not crawl sites.
Does DAX measure my campaign?
No. DAX 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 Site Monitor, or verifying a site, never changes its score or its rank.
Is this a Google rating?
No. DAX 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. DAX 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 publishers and the ones with the weakest experience, each with the main reason. No sign-up.
