BUILT FOR INDIRECT DISTRIBUTION
Your lines travel further
than your visibility.
You know your partners. But which publishers carry your lines? Which apps name your seller IDs? And where does a missing upstream listing leave the relationship incomplete?
Bring the listings and the relationships behind them into one view.
Then, see what doesn’t add up.
Check seller records and upstream relationships across web and app. Group findings by cause so your team can see what needs attention.
YOUR PRIORITIESGive the right team a next step.
Share the affected properties, source evidence and specific issue with the publisher or partner responsible. Make the follow-up concrete.

FINDINGS THAT LEAD SOMEWHERE
A named problem.
A clear person to ask.
Keep the finding, affected property and responsible party together. These fictional rows illustrate how the evidence becomes a practical follow-up.

Missing seller record
The publisher lists an ID the SSP’s sellers.json does not contain.
FIXED BYYou or the SSPMissing upstream listing
The company named above you has no listing of its own on the publisher.
FIXED BYPublisher or SSPConflicting relationship
The publisher says RESELLER; the seller record says PUBLISHER.
FIXED BYYou or the SSPMalformed ads.txt line
A damaged field or a missing line break makes the declaration invalid.
FIXED BYPublisherA VERDICT HAS TO BE EARNED
“We can’t verify it”
is an answer, too.
Confidential records and incomplete data don’t become false alarms. We distinguish a demonstrated fault from a path we cannot check — and tell you why.
Clean
The checked records agree.
Broken
A specific fault, supported by source evidence.
Unverifiable
The relationship cannot be checked.
Not enough data
Held back from judgement, with a reason.
THE DATA BEHIND THE CHECK
Crawled before you ask.
Web
CHECKS LIVEPublisher ads.txt files, cross-checked against seller records.

A LITTLE MORE CLARITY
Good questions.
What do you need from me?
Your seller domain. Start with the lookup above, or book a walkthrough. We use the public files already in our index to find your listings and check the relationships behind them.
Can anyone see all of my report?
Public summaries are available for selected ad systems that have already been analysed. Detailed affected properties and the source evidence are shared with a verified address at your company.
Does this fix publisher files automatically?
No. We show the fault, the evidence and who can fix it. Your team works with the publisher or SSP to make the correction in the file they control.
Does this find my listings or check for problems?
Both. Discover matching listings across the web, app and CTV files in our index. For web and app, we also check the seller relationships behind those listings and show findings with source evidence and a responsible party.
Does this cover every property on the internet?
Results cover matching properties in our indexed public files. Coverage varies by channel; a property that is not in the index will not appear in the report.
What if a finding is wrong?
Tell us and a real person will investigate. Confirmed errors are corrected across the accounts they affect. Missing or incomplete data is explicitly distinguished from a demonstrated defect.
