DIRECT lines for seats the publisher doesn't own

50 −12 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

21 −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.

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

Ad systems without a public sellers.json
