AI Shopping Is Rewriting Consumer Behavior: The Hidden Signals Brands Can't Afford to Ignore

Last week, I facilitated a closed-door workshop with brand leaders, retailers, agencies, and technology partners at the P2PI Retail Media Summit in Chicago. While much of the conversation centered on AI's impact on retail media and shopping behavior, what surprised me most wasn't panic: it was curiosity. Despite all the headlines about disruption, most brands aren't seeing dramatic changes in ad performance or sales outcomes just yet.What is changing, however, is where shopping journeys begin. In this episode, I unpack the emerging signals brands are seeing as consumers increasingly turn to AI assistants, communities, and social commerce platforms for product discovery. I explore the rise of "dark search," why traditional attribution models are becoming less reliable, the new metrics brands are experimenting with, and which retail media channels may be best positioned to withstand the AI-driven shift in shopper behavior.This episode is sponsored by Mirakl AdsTimeline[00:00] Highlights from a closed-door workshop at the P2PI Retail Media Summit in Chicago[02:03] What brands say is holding steady: ad conversions and sponsored product performance remain resilient[03:00] The biggest shift brands are seeing: shopping journeys are increasingly starting outside traditional search[03:45] Why Reddit, Pinterest, Wikipedia, TikTok Shop, and AI assistants are becoming key discovery channels[05:50] Understanding "dark search" and why AI-driven influence is often invisible in analytics platforms[07:33] New measurement frameworks emerge, including "share of agent recommendations" and agent readiness[08:21] Which retail media channels may be most defensible against AI disruption, and why influencers could have a lasting advantageLinks & ResourcesThe Agentic AI Revolution is here.
