MIAMI — Post-transaction advertising delivers measurably stronger results than traditional display, but the programmatic infrastructure built to serve the open web may be holding marketers back from realizing its full potential.
“The unique thing about post-transaction is high-impact inventory, and it’s brand safe because a real person just made a purchase, which drives incredibly strong performance and click-through rates,” Matt Conlin, co-founder & CCO of Fluent, told Beet.TV contributor David Kaplan at POSSIBLE. Fluent sees 2.5% click-through rates from post-transaction placements, compared to the 0.25% CTR typical of traditional display. “Programmatic was built on the open web where there were a lot of display ads cluttering a publisher’s webpage. Programmatic was not built to support that type of performance.”
This infrastructure mismatch explains why post-transaction inventory remains largely outside programmatic ecosystems despite delivering perfornace comparable to branded search.
Commerce media reaches third growth phase
After maximizing endemic advertiser onsite inventory and expanding offsite audience targeting, commerce media enters phase three through new ad verticals and surface area that go beyond traditional placement strategies.
“As both of those first two phases of growth have started to plateau, the next natural stage are what are the other types of ad verticals we can introduce to our shoppers to enrich the experience?” Conlin said.
New opportunities include order return pages, summary pages, loyalty sections, and in-store experiences — moments when purchase intent is high and consumer attention is still fully engaged. That post-transaction window, when a shopper’s excitement and trust are at their peak, is where Fluent believes the most underutilized value in commerce media sits.
Personalization requires privacy balance
Effective commerce advertising depends on relevance — but relevance requires data, and data requires trust. The challenge is building personalized ad experiences on shopper insights while maintaining privacy compliance and delivering the conversion signals advertisers need to close the loop.
“How do we create the most relevant and personalized ad experience possible based on what we know about a shopper? And how do we do that in a privacy safe way that respects privacy but also delivers the personalization that shoppers have come to demand?” Conlin said.
Data flows bidirectionally, with retailer insights informing advertiser targeting while conversion feedback enriches commerce partner’ understanding of their own customers.
Prioritize customer experience
Success in commerce media’s next phase won’t just come from innovation — it will come from knowing what not to compromise.
“The winners are ultimately those that preserve the best experience possible for the shoppers, keep their customers loyal and coming back time and time again, while also introducing appropriate ways for brands to participate in that customer journey,” Conlin said. “Those that are focused on driving GMV while also creating rich customer experiences.”
Sustainable growth, in Conlin’s view, means treating shopper loyalty as the asset worth protecting — not a variable to optimize against.
