GEO & AI search

Structured data

schema.org

Definition

Markup embedded in a page, such as Product or FAQPage schema, that tells both search engines and AI assistants exactly what a piece of content is, rather than making them infer it.

Defined in The Agentic Commerce Glossary.

How else it gets framed

The same term carries different emphasis depending on the surface it’s used on. Both readings are correct.

Machine-readable markup — typically JSON-LD using schema.org vocabulary — that labels facts on a page explicitly: Product name, Offer price, AggregateRating, FAQPage question/answer pairs. It exists alongside the human-readable page, not instead of it.

Related terms

Retrieval-augmented answer
An AI response generated by first searching for relevant live pages, then having the model read and synthesize from those specific pages — as opposed to answering purely from training data. Perplexity's shopping answers are retrieval-augmented, which is why what's on your page right now matters more than what a model "knows" about your brand.
Commerce GEO
Generative engine optimization applied to commerce — the practice of structuring a catalog and content so AI assistants like ChatGPT, Claude, Gemini, and Perplexity cite and recommend it.
Shared foundation
Technical and data work — structured data, attribute completeness, site architecture, page performance — that simultaneously improves classic search rankings and AI-assistant citation accuracy. It should be budgeted once, not split across SEO and GEO line items.
Answer-first structure
Writing the conclusion or direct answer as the first sentence of a section, with supporting reasoning and caveats following it — the inverse of narrative or journalistic structure, which builds to a conclusion.
Corroboration
Independent confirmation of a claim from a source that isn't the brand itself. In GEO terms, it's the difference between a fact an assistant can state with confidence and one it has to hedge or omit.
Server-side rendering
Generating the full HTML — including product facts and JSON-LD — on the server so it's present in the initial response, before any JavaScript runs. The opposite of client-rendering facts into the page after load.
