JSON-LD

JSON-LD 구조화 데이터

JSON-LD combines JavaScript Object Notation with linked-data concepts that connect entities and their meaning. Its principal advantage is that it can be inserted independently in a script element without restructuring the surrounding HTML. Google recommends JSON-LD where possible because it is generally easier to maintain and generate through automated pipelines than embedded Microdata or RDFa. Multiple entities can be represented together in an array or graph, keeping complex pages manageable.

Business applications and impact#

Separates structured data from presentation markup and supports maintainable automation.

Implementation guidance and considerations#

Use Google’s Rich Results Test to check syntax and required-property errors, including missing fields.
