The AI Purchase Channel does not reward the marketing tactics that worked in display, search, social, and shelf.

Why new brands win the AI Purchase Channel
The AI Purchase Channel rewards three things: specificity, memory, and being right. New brands are built around exactly one — themselves, for one customer, said precisely.

Narrative Accuracy vs Share of Voice in the AI Purchase Channel
Narrative Accuracy is the degree to which an AI assistant’s claims about your brand — its ingredients, its positioning, its price point, its persona, its provenance — are true to your owned positioning.

The AI Purchase Channel: A Field Guide
The AI Purchase Channel is the new buying channel where shoppers – humans assisted by AI agents OR AI agents without human intervention – complete the shopping journey.

It is the closest measurable proxy for revenue from the channel — and it is what visibility and ranking metrics, inherited from search, were never built to measure.
