JSON-LD

A JavaScript-based format for adding structured data to a web page, recommended by Google for schema markup.

JSON-LD sits in a script block of type application/ld+json and does not need to be mixed into the visible HTML, which makes it easier to add and maintain than Microdata or RDFa.

Create JSON-LD in seconds with our schema markup generator.
