warning

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

17 −13 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.

info

DIRECT accounts registered to another domain

1 −2 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.

info

No OWNERDOMAIN declared

1 −2 pts

app-ads.txt 1.1 recommends OWNERDOMAIN so buyers can match DIRECT accounts to the owner.

How to fixAdd OWNERDOMAIN=<your company domain> to the file.

Duplicate lines

11 −1 pts

info

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.
