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

30 −2 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 lines inconsistent with public data

9 −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.

Lines for ad system domains that don't resolve

How to fixRemove these lines. If the domain is registered again, its new holder would appear authorized by your file.

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.
