Curation is one of the most talked-about trends in programmatic, and one of the least understood.
Supply platforms miss the key ingredient when they treat curation as a cosmetic upgrade of previous approaches: Package a few domains, add a data partner, and throw a bow on it. The result is more deal IDs and complexity, but not necessarily better outcomes.
Here’s the thing: if no one reshapes the underlying infrastructure, then we’re not curating. We’re just repackaging.
More Than Dumb Pipes
Platforms that continue pushing volume through legacy systems not built for today’s demands are often called dumb pipes. Programmatic is about volume at scale, but it’s also about precision at speed. The only way to deliver both is through modern infrastructure and a fundamentally different approach to shaping inventory for demand.
What might that involve? Here are three possibilities:
- Placement-level shaping: One could filter inventory based on core quality and attention signals before it reaches a DSP.
- DSP seat-level shaping: One could optimize traffic based on how each DSP, agency, or advertiser seat bids and performs.
- Buy-side data shaping: One might incorporate KPI feedback to refine supply around what truly converts.
Curation along those lines would affect not only who sees supply, but also which impressions would perform.
Why Infrastructure Matters
Curation isn’t just a data problem. It’s also an infrastructure challenge.
DSPs have traditionally operated in a “burn-and-learn” environment, sifting high-quality impressions from a flood of irrelevant supply in the bidstream. QPS (Queries Per Second) limits and deal throttling were introduced to manage this flood, but they didn’t improve access to all the impressions that matter for specific buyer needs. Problematic ads still slip through, including high ad-refresh and ads-to-content ratio placements on reputable sites. Meanwhile, high-quality, high-attention placements across the diversity of the premium open Internet are easily overlooked.
The result? DSPs keep buying the same limited slices of inventory on the same generic basis.
Advanced curation platforms could apply sell-side decisioning to dramatically reduce this technical burden for DSPs, simplifying the path to high-quality, more performant media.
This approach would also provide significantly higher addressability and scale for data targeting, and would enable earlier inventory decisioning, dramatically improving quality outcomes for the demand side.
Publishers would increase revenue through higher CPMs on well-defined inventory segments. Buyers would benefit from greater confidence, improved campaign outcomes, and simpler planning. The overall ecosystem would exhibit reduced complexity, stronger performance, and increased transparency.
If your platform is still built on legacy architecture, static pricing, and post-bid optimization, you’re not curating. You’re flooding the market.
True curation could begin behind the scenes, by shaping impressions at the placement level, by dynamically adapting pricing to specific buyer needs, and by processing decisions at scale.
That’s what it would take to make the open web perform better for both advertisers and publishers.
