JSON-LD
JavaScript Object Notation for Linked Data — the recommended format for embedding schema.org structured data in web pages.
JSON-LD is the format Google and other search engines recommend for marking up structured data. It sits in a <script type="application/ld+json"> block, typically in the page <head>, and contains a JSON object describing the page's entities.
Why JSON-LD instead of Microdata or RDFa?
JSON-LD separates the markup from the visible HTML, so designers can change visual layout without affecting structured data. It's also easier to validate and easier for AI engines to parse.
What does a minimal JSON-LD block look like?
Three fields: @context (always "https://schema.org"), @type (the schema type, e.g. "Article"), and the type-specific fields like headline, datePublished, author. Validate with Google's Rich Results Test.
