Addressability and UMPs Dominate Discussion at Prebid Summit
· 2h ago · Originally reported by Digiday
At this year's Prebid Summit, attendees focused on addressability challenges in digital advertising. Speakers expressed concerns that User Management Platforms (UMPs) are becoming as opaque as old ad networks, with industry conversation outpacing actual understanding.
Why it matters
Addressability—how advertisers reach the right audiences—is a core issue as privacy changes disrupt established methods. If new solutions like UMPs are poorly understood, it could lead to inefficiencies and wasted ad spend.
