The AEO glossary

The fast-moving vocabulary of AI shopping, in plain English.

AEO (Answer Engine Optimization)

Making a store visible to the AI agents that shop on customers’ behalf — the agent-era counterpart to SEO. Deep dive →

AI shopping agent

An assistant (ChatGPT, Claude, Perplexity) that finds and compares products for a shopper, returning a short list rather than a page of results.

Catalog endpoint

The machine-readable feed of your products an agent queries directly — titles, prices, attributes. If you don’t expose one, agents can’t see you.

UCP (Universal Commerce Protocol)

The open standard for how agents discover and shop a merchant’s catalog. Explainer →

Blind spot

A shopper query your store returns nothing for — a search where you’re invisible to an agent. Closing blind spots is the core of AEO. Find yours →

AI-visibility score

How often agents surface your store across the queries shoppers ask in your category — the headline number on your store report.
