Ads only after relevance and measurement
Andrew Yates, CEO of Promoted.ai, on when marketplaces should layer on ads
The real moat in marketplace ads is not the story, it is the operating system underneath. What separates a working ads or discovery product from a slide deck is an end to end stack that measures what users did, connects that behavior to bookings or purchases, and keeps search results reliable enough that buyers return and sellers keep investing. In practice, most marketplaces talk about owning this capability long before they have shipped the data pipelines, ranking models, attribution, and testing loops that make it work.

Promoted is built around the hard parts that marketplaces usually underestimate, ranking search results, tracking the full path from click to transaction, and proving lift with A/B tests. That is why Andrew Yates frames ads as optional monetization on top of a measurement and relevance engine, not the product itself.

The comparison point is companies like Netflix, where recommendations are the product and worth building in house. For most marketplaces, the real differentiator is selection, logistics, or supply, so building a world class retrieval and ads stack internally can soak up years of effort without changing the core customer reason to use the platform.

The economic temptation is obvious because ads are high margin once they work. Mirakl pushed into retail media with Mirakl Ads, and Rokt built a large network around checkout monetization. But both examples reinforce the same point, ad dollars show up after the platform has traffic, seller demand, and infrastructure that can price and prove incremental value.
This pushes the market toward specialized infrastructure providers. Large platforms with search as a core product will keep building internally, but the broader marketplace stack is moving toward buying the plumbing and focusing internal teams on supply, fulfillment, and customer experience. The winners will be the ones that turn relevance and monetization into a dependable operating capability, not a financing narrative.
