What is JSON-LD?

JSON-LD (JavaScript Object Notation for Linked Data) is a format for embedding structured data in web pages. It uses a @context to link to Schema.org or other vocabularies, enabling search engines to understand content—organization, products, articles, local business, etc. JSON-LD is placed in a script tag with type="application/ld+json". Google, Bing, and others use it for rich snippets and knowledge panels. Unlike microdata or RDFa, JSON-LD is easy to add and doesn't require HTML changes.
