For decades, retail and CPG brands have competed for visibility on retail shelves and online. The key is to show up where consumers are actively looking. The old model assumed a human shopper typing queries, scanning aisles, and making decisions based on what they could see.
But with AI, consumer behavior is changing.
The rise of the AI-mediated shopper
A growing share of consumers are no longer browsing the way they used to. Instead of typing "running shoes size 10" into a search bar, they're asking AI assistants to find options, compare prices, and in some cases, make purchases on their behalf. Nearly a quarter of consumers have already made an AI-assisted purchase, and more than half are replacing traditional search engines with AI tools for product recommendations, according to recent research, including from global consulting firm Capgemini.
This is an important structural change in how demand is surfaced and captured, and it's accelerating fast.
What changes when AI is the buyer
When a consumer delegates a purchase decision to an AI agent — say, restocking household essentials or finding the best deal on a seasonal item — that agent doesn't browse an aisle. It doesn't notice end-cap displays or respond to brand packaging. It evaluates products on objective parameters: price, ingredients, reviews, delivery promises.
That's a fundamentally different buying process. And it raises a question most retail and CPG teams haven't had to ask before: If an AI agent had to describe your brand or your product in a sentence, would it get it right? And would that sentence be compelling enough to win the sale?
From SEO to GEO
The industry has spent years optimizing for search engine visibility. But as AI platforms become major gateways to shopping, a new discipline is emerging: Generative Engine Optimization, or GEO. Where SEO was about ranking in a list of links, GEO is about being accurately represented and recommended in AI-generated responses.
This has implications far beyond marketing. It touches product data, content strategy, and how brands structure information across every digital touchpoint. If your product taxonomy uses internal language that doesn't match how real people talk about your products, AI systems might not find you.
The strategic question
This shift doesn't just affect e-commerce teams. It challenges core assumptions about where marketing dollars go, how brand equity is built, and what "discoverability" even means in a world where the consumer's first interaction with your product might be mediated entirely by an algorithm.
Some organizations are already adapting by rethinking their product data architecture, exploring agent-optimized experiences, and measuring AI-driven conversion as a distinct channel. Others are still fully reliant on the traditional model.
The gap between those two groups is widening quickly and pushing some competitors ahead.
