Structured data is the GEO infrastructure layer. A page that lists pricing in plain prose forces the AI engine to guess; the same pricing wrapped in Product schema with offer fields is unambiguous and citation-ready. The marginal effort to add JSON-LD is small; the marginal lift on AI citation rate is consistently meaningful.
GEO glossary
Structured data
Structured data is page content annotated in a machine-readable format, JSON-LD, microdata, or RDFa, so AI engines and search crawlers can interpret meaning beyond the raw text.
