JSON-LD

JSON-LD (JavaScript Object Notation for Linked Data) is the structured data format recommended by Google for implementing Schema.org markup on web pages. It is added as a script tag in the HTML head or body, keeping structured data separate from the visible page content.

JSON-LD is preferred over Microdata and RDFa because it is easier to implement, maintain, and debug. It does not require modifications to existing HTML, can be dynamically generated by CMS systems, and is the format most reliably parsed by both search engines and AI systems.

Implementation involves adding script tags with type "application/ld+json" containing JSON objects that describe your page content using Schema.org vocabulary. Multiple JSON-LD blocks can be included on a single page to describe different aspects (organization, article, FAQ, breadcrumbs).
