JSON-LD
Definition
JSON-LD (JavaScript Object Notation for Linked Data) is a method of encoding structured data using JSON syntax. Google recommends JSON-LD over other structured data formats (Microdata, RDFa) because it can be added to a page's <head> section without modifying the HTML content. This makes it easier to implement and maintain. JSON-LD uses @context and @type properties to define the vocabulary and entity type, then lists properties relevant to that type. For example, a LocalBusiness schema includes name, address, phone, and opening hours. Multiple schemas can be combined using @graph to describe multiple entities on a single page.
