<b>Double-listed SSPs are flagging your supply</b>
Confirmed: when the same SSP appears in ads.txt as both DIRECT and RESELLER for one publisher, DSPs treat it as ambiguous authorization and some down-weight the bid. It happens when you sign direct but forget to remove the reseller line a network added years ago.
— Grep your ads.txt for duplicate domains with conflicting relationships
— Keep DIRECT, kill the orphaned RESELLER
Impact: ambiguity reads as risk to the buy side. Confidence: confirmed.
