Each finding lists the exact lines involved. Findings are automated observations of public files as of Oct 7, 2026. They describe file contents, not the intent or conduct of any company.

warning

DIRECT lines inconsistent with public data

36 −10 pts

The ads.txt specification defines DIRECT as an account the publisher directly controls. For these lines, either the ad system's own sellers.json lists the account as INTERMEDIARY, or the same account is marked DIRECT in the files of 3 or more unrelated companies. Either way, the public data does not support the DIRECT label. Buyers that use DIRECT labels in supply-path decisions may treat these lines differently.

How to fixUse DIRECT only for accounts your company controls. Confirm with each partner whether the account is yours; if it isn't, the specification calls for RESELLER.

warning

Seller IDs not listed in the ad system's sellers.json

25 −8 pts

The ad system's current sellers.json doesn't list these accounts, so buyers that validate the chain can't match them. Common causes are closed accounts or former partners.

How to fixAsk each partner whether the account is still active and request their current lines; remove lines for closed accounts.

DIRECT accounts registered to another domain

34 −5 pts

Allowed when the domain belongs to the same company; add OWNERDOMAIN to make that explicit. Otherwise these accounts may belong to someone else.

How to fixIf the account is yours under another domain, declare it with OWNERDOMAIN=<that domain>; otherwise mark it RESELLER.

Ad systems without a public sellers.json

The ad system doesn't publish a readable sellers.json, so nobody can verify these lines. That's the ad system's gap, not the app's, so no points are deducted.

How to fixAsk the partner to publish sellers.json; until then buyers can't verify that path.
