Inside the Buyer Black Box: How the Buy Side of Programmatic Evaluates Supply Paths
About the podcast
In this episode of Web Without Walls, Vijay Kumar sits down with Eric Tilbury, Vice President Programmatic Ops & Solutions Engineering at Inuvo, to unpack what actually happens after a publisher sends an ad request into the exchange.
Drawing from years spent managing campaigns, optimizing supply paths, and auditing inventory quality, Eric breaks down how buyers evaluate bid requests in real time, why reseller noise and supply-path complexity create major inefficiencies, and how publishers unknowingly end up on permanent blocklists.
The conversation explores the realities behind SPO, PMP pricing, curation, sell-side decisioning, contextual targeting, and QPS management, while also challenging how most programmatic buying is executed today. Eric shares why clean supply matters more than most buyers admit, why curation could become the future of RTB, and how ID-free environments are reshaping programmatic performance.
For publishers trying to understand the buy side’s decision-making process and the hidden mechanics impacting yield, this episode offers an unusually transparent look inside the programmatic black box.
