*Technical implementation* · *Structured Data*

## Definition

Structured data is information about a web page's content that is formatted using a standardized vocabulary — most commonly schema.org — and embedded in the page's HTML so that search engines and AI crawlers can interpret it without relying on natural language parsing. JSON-LD is the recommended implementation format.

## Why It Matters for AI Search

Structured data is the most direct mechanism for communicating entity information to AI systems. Where natural language requires interpretation, structured data is declarative — it states facts about a page's content, entity type, and attributes in a format designed for machine consumption. For AI search, structured data reduces ambiguity, confirms entity identity, and provides a reliable extraction surface that AI systems can trust over inferred information from prose. Every page that carries correct structured data is a more reliable AI citation source than the equivalent page without it.
