Episode description

Welcome to The Ecommerce Braintrust podcast, brought to you by Julie Spear, Head of Retail Marketplace Services, and Jordan Ripley, Director of Retail Operations. In today's episode, we're diving into a topic that's been heating up since Amazon unveiled it at Unboxed last October: using AMC audiences for Sponsored Products.  It's a conversation that's gone from a slow simmer to a full-on boil in recent months, and we've brought in two of Acadia's sharpest retail media minds to break it all down: Ross Walker and Carlos Sastre. We'll be exploring where the real impact is showing up, what's working, and what this shift means for the future of Sponsored Search. Tune in to find out more! "I don't care about winning every single eyeball for a keyword. I only care about winning the subset of eyeballs that are most likely to convert, be a high lifetime value customer, or be most likely to purchase multiple products in my assortment. That is the new game that we are moving towards in the future." Ross Walker KEY TAKEAWAYS In this episode, Julie, Jordan, Ross, and Carlos discuss: Overview of AMC Audiences for Sponsored Ads: The distinction between using AMC audiences in DSP vs. Sponsored Ads. In Sponsored Products/Brand Ads, AMC audiences act as bid modifiers rather than strict targeting mechanisms. Limitations and Current Capabilities: Advertisers can only boost bids for specific audiences, not exclude or exclusively target them. Only one AMC audience can be applied per campaign currently, which introduces campaign complexity
