What GEO / AEO practitioners can learn from Gary Marcus
- **Product data becomes the fuel**: structured, accurate, machine-readable product information decides whether your items enter an agent’s consideration set. - **Trust and rules**: governance of payments, liability and authorization determines whether an agent dares transact with you on a user’s behalf. - **Agent Experience (AX)**: after UX, making AI agents understand and choose you efficiently becomes the new discipline.
What it means for brands going global
For DTC and ecommerce brands going global, agentic commerce is both threat and opportunity: the sooner you shape product data, reviews and trust signals into a machine-readable, trustworthy form, the more likely you are to be chosen in agent-led shopping.
