Most ecommerce brands think their retargeting is handled. They're running Criteo or Performance Max, hitting their ROAS targets, and moving on.

Here's the problem: their platform is only reaching 15–20% of the visitors who bounced from their site. The other 80–85% never see their brand again.

In this episode of Inside the Blurb, I sit down with Jason Blom — VP of Strategic Opportunities at RTB House and former Criteo sales leader — to break down what deep learning retargeting actually does differently, and whether adding a second retargeting partner is worth it.

We cover:

✅ Why no single retargeting platform can reach more than 15–20% of your eligible audience

✅ Deep learning vs. machine learning — what the difference actually means in practice

✅ Why 60%+ of RTB House-driven purchases happen on products shoppers never viewed or carted

✅ The exact framework for setting up a clean incrementality test

✅ What RTB House collects that standard retargeters don't (beyond the 5 standard pixels)

✅ How RTB House's creative philosophy differs from the ugly retargeting ads you're used to

✅ The question most brands forget to ask when evaluating a lower-funnel partner

This isn't a pitch — it's a candid conversation between two former Criteo colleagues who know this space inside and out.
