Heard: adding two ID solutions raised addressable fill 14%
A publisher with 60% Safari/iOS traffic was bleeding cookieless impressions.
— Added two alternative ID providers to the Prebid user-ID module
— Passed hashed-email IDs on logged-in inventory
— Addressable rate on cookieless traffic went 31% to 45%
Matched-rate CPMs on those impressions ran 2.3x the unmatched rate, lifting total programmatic revenue meaningfully.
Impact: Cookieless inventory isn't worthless, it's unmatched. Fix the ID layer.
