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.
