The Bid Request Has Receipts: Eric Tilbury on Clean Supply, ID-Free Buying, and the Craft of Programmatic

<p>Programmatic advertising has spent years getting smarter about audiences. But what if the bigger problem is that buyers still don’t fully understand what they’re actually buying?</p><p>Eric Tilbury, Vice President of Programmatic Ops &amp; Solutions Engineering at Inuvo, joins Rio Longacre and Brett House for a deep dive into the machinery underneath modern programmatic advertising—and why better technology doesn’t necessarily produce better media buying.</p><p>Eric is an operator first. He has spent more than a decade inside campaign management, supply optimization, contextual decisioning, CTV, DSPs and the plumbing that determines whether a bid request ever reaches a buyer in the first place.

Cheap CPMs and attractive platform metrics can conceal low-quality placements, opaque reselling, bot traffic and inventory no advertiser would intentionally choose.</p><p>The discussion also gets into one of Eric’s biggest contrarian ideas: <strong>iOS and other ID-light environments may represent an overlooked buying opportunity.</strong> When advertisers optimize around what is easiest to identify and attribute, they can systematically ignore valuable consumers—and sometimes reward the inventory most capable of gaming their measurement systems.</p><p>Eric also breaks down Inuvo’s IntentKey approach, which uses content, concepts, sentiment and real-time signals to make buying decisions without building the decision around an individual user profile.</p><p>And then the conversation turns to measurement. Eric argues that platform ROAS, CPA and CTR should be treated as directional optimization metrics—not as the ultimate source of truth. If advertising is actually working, the question should be whether it created increm
