Findings

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

1 −2 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.

DIRECT accounts registered to another domain

1 −1 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

15

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.
