Structured Data

Structured data is data organized in a predictable, machine-readable format that allows software systems to parse, interpret, and use it reliably. In the web context, structured data refers specifically to markup added to web pages that communicates content meaning to crawlers and AI systems using standardized vocabularies. The most common vocabulary is Schema.org, which defines thousands of types covering virtually every kind of entity and content on the web. The most common delivery format is JSON-LD, a compact, clean JSON format that can be added to the page head without modifying the visible HTML. Structured data tells search engines and AI systems: this page is an Article, written by this Person, published on this date, about these topics. Without structured data, systems must infer all of that from the page text. With structured data, you state it explicitly, reducing ambiguity and improving the accuracy of how your content is interpreted and retrieved.
