DIRECT lines for seats the publisher doesn't own

36 −10 pts

DIRECT should mean the publisher controls the account. These seats are listed as intermediaries by the ad system itself, or are labeled DIRECT by many unrelated companies, so they belong to a reseller. Buyers who prefer DIRECT paths end up paying for an extra hop.

How to fixUse DIRECT only for accounts your company controls. Ask each partner whether the seat is yours; if not, change the line to RESELLER.

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

27 −8 pts

The ad system's current sellers.json doesn't list these accounts, so buyers that validate the chain can't match them. Usually leftovers from closed accounts or old partners.

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

Lines for ad system domains that don't exist

1 −1 pts

These ad system domains don't resolve: the company shut down or merged, or the domain is misspelled. The lines authorize nothing, and whoever registers the domain would inherit them.

How to fixRemove these lines. A dead domain can be re-registered by anyone, who would then inherit your authorization.

DIRECT accounts registered to another domain

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.
