JSON-LD

Tue, 03 Mar 2026 00:00:00 +0000

JSON-LD (JavaScript Object Notation for Linked Data) is a method of encoding structured data using JSON syntax. It allows web pages to embed machine-readable descriptions of their content — what kind of thing a page describes, who created it, when it was published — alongside the human-readable HTML.

How it works

A JSON-LD block is placed inside a <script type="application/ld+json"> tag in the page’s <head> or <body>. It contains a JSON object with a @context (typically https://schema.org) and a @type declaring what kind of thing is being described.

Schema.org is a collaborative vocabulary for structured data on the web, maintained jointly by Google, Microsoft, Yahoo, and Yandex since 2011. It provides a shared set of types (like Article, Person, DefinedTerm) and properties (like author, datePublished, description) that web pages use to describe their content in machine-readable form.

How it works

Schema.org defines a type hierarchy. Thing is the root. Below it sit types like CreativeWork (which includes Article, Book, LearningResource), Person, Organization, and Place. Each type has properties that describe instances of that type.
