A JSON-based format for embedding Schema.org structured data in a page — the lingua franca that AI engines extract.

long_def

JSON-LD 1.1 is a W3C Recommendation (2020). A single script tag with an @graph can describe a site, its pages, its author and its key entities in a way that Google, Bing, Perplexity and ChatGPT all parse. By 2026, engines cross-check schema claims against page content, so accuracy matters more than volume.

Developed at the W3C; JSON-LD 1.0 reached W3C Recommendation in 2014 and JSON-LD 1.1 in 2020. Manu Sporny (Digital Bazaar) was the original 1.0 editor/author; 1.1 editors include Gregg Kellogg, Pierre-Antoine Champin and Dave Longley.

contrast_with

Unlike microdata or RDFa, which inline structured data into HTML tags, JSON-LD lives in a self-contained script block — decoupled from markup and far easier for engines to extract.

example

JSON-LD 1.1 became a W3C Recommendation in 2020; a single script tag with @graph lets Google, Bing, Perplexity and ChatGPT parse a page's entities.

why_it_matters

JSON-LD is the structured-data format AI engines extract first; correct, page-consistent JSON-LD is a primary lever for getting entities understood and cited.
