Sensor Tower SVP Ian Simpson breaks down Holiday ’25 funnel data, conversion lift, and what brands should do next.

In this episode, Scot digs into a question he keeps getting from readers and listeners: What’s actually going on inside Amazon’s Rufus, and what should brands do about it?Ian brings fresh analysis from Sensor Tower’s panel-based methodology (privacy-compliant, double opt-in), walking through Holiday ’25 shopping sessions to show where Rufus shows up in the funnel, how usage spikes during peak moments, and why it appears to correlate with dramatically higher conversion. Along the way, they zoom out to the bigger shift: as more people learn to “talk to AI” (thanks to ChatGPT-style habits), conversational shopping becomes increasingly normal, and increasingly hard to “optimize” using old keyword-era tactics.Highlights:“The consumer is trained.” A year of daily conversational AI use has taught people how to prompt, so when they see Amazon Rufus, they already know how to use it.Rufus sessions show a major conversion lift. In Ian’s read of the report: ~3.5× lift vs. non-Rufus sessions, with Rufus-touch sessions far more likely to end in purchase.Rufus had outsized influence during Holiday ’25. A large share of purchases included Rufus interaction, even if not every session did.Their team mapped ten distinct Rufus-assisted shopping paths, including the standout “Research Conversationalist” profile.Correlation vs causation is real. Ian flags measurement caveats: not every “non-Rufus session” is a shopping mission; intent bias exists; so the takeaway is directional, but meaningful.Brands should shift from “keyword jail” to “product truth.” Better attributes, clearer specs, stronger review signals, and real storytelling matter more in conversational shopping.AEO anxiety + the brand-level rebound. Ian argues the future isn’t just “optimize for prompts”, it may reward brands with stronger reputation and social proof signals (think forums and communities).AI can talk consumers out of premium. They’ve seen examples where AI steers price-sensitive users away from expensive brands, an early warning system for brand teams.Retail media won’t vanish, but it will mutate. In a lower-click world, retailers will experiment heavily to preserve value, without turning the experience into ad soup.If you’ve been treating Rufus like a curiosity, this data makes it hard to ignore: conversational commerce isn’t “coming”, it’s already shaping how high-intent shoppers decide.Timestamps:00:00 – The Consumer Is Now Trained02:09 – Why This Episode Focuses on Rufus05:49 – Ian Simpson’s Background06:47 – Founding a Bottled Tea Startup09:14 – Pathmatics → Sensor Tower Acquisition10:11 – How Retail Media Intelligence Was Born13:50 – How Sensor Tower Delivers Its Data15:36 – Why Sensor Tower Started Tracking Agentic Commerce21:08 – How the Rufus Analysis Was Done22:48 – The 3.5× Conversion Lift Explained24:18 – Amazon’s $10B Rufus Claim vs. Independent Data28:16 – Correlation vs. Causation in Rufus Usage31:23 – Rufus as a Research Companion32:20 – The Cup Holder Story (Problem-Based Shopping)39:55 – Why Rufus Usage Sticks After the Holidays40:19 – The 10 Rufus Shopping Profiles41:35 – The “Research Conversationalist” Funnel45:00 – Why “AEO” Makes Ian Nervous46:47 – Brand Matters Again in Agentic Commerce48:47 – When AI Talks Consumers Out of Premium Products58:21 – Retail Media’s Future in a Low-Click World01:01:31 – Avoiding the Minority Report Ad Nightmare01:06:21 – Instacart: The Wild West of Retail Media01:07:15 – Where to Follow Ian👉 Connect with Ian: https://www.linkedin.com/in/iansimpson/👉 Learn more about Sensor Tower: https://sensortower.comCheck out the materials we discuss: 🔗 Sensor Tower Black Friday AI Trend Update  🔗 How Amazon’s Rufus Shaped Holiday Shopping🧠 Want to stay ahead in AI commerce?
