JSON-LD

JSON-LD (JavaScript Object Notation for Linked Data) is a lightweight Linked Data format that adds semantic context to JSON data, enabling it to be interpreted as structured data on the web. It allows developers to embed machine-readable metadata in JSON documents, making data easily understandable by search engines, APIs, and other applications. By using standardized vocabularies like Schema.org, JSON-LD helps create a more interconnected and intelligent web.

Also known as: JSON for Linked Data, JSONLD, JSON Linked Data, JSON-LD 1.1, JSON-LD 1.0

Why learn JSON-LD?

Developers should learn JSON-LD when building websites or applications that require rich snippets in search results, such as e-commerce sites, blogs, or business listings, as it improves SEO and data interoperability. It is essential for implementing structured data to enhance visibility on platforms like Google, Facebook, and Twitter, and for integrating with semantic web technologies to enable data linking across different sources.
