- Schema Markup – Structured code telling AI crawlers your product’s price, specs, and reviews instantly.
- PDP (Product Detail Page) – Your storefront for AI, which must be LLM-readable to get recommended.

- Zero-Click Commerce – A purchase completed entirely inside a chat interface, where the shopper never visits your site.
- Catalog Enrichment – Rewriting product data so LLMs can read, understand, and recommend your items.

How to Actually Use This Glossary
- Turn each term into a yes/no checklist for your store: do you have it, or are you guessing.
- Prioritize visibility levers first: GEO, AEO, AI-SOV, citation frequency, and schema markup.
- Then fix your product layer: catalog enrichment, PDPs, chunking, and UGC that AI trusts.
- Finally, play offense with agents: agentic commerce, UCP, MCP, and A2A-ready workflows.
Real-World Style Plays Using These Terms
Amazon rewrites PDPs with rich schema markup and catalog enrichment so its products dominate GEO and AEO results inside AI shopping assistants.
Shopify helps merchants boost AI visibility by baking structured data, fast SSR, and UGC widgets directly into storefront themes.
