# JSON-LD

JSON format for linked data, embedded in a script tag with schema.org types. AR-READ-08 asks for it on key pages with facts repeated in visible text. Example: <script type="application/ld+json">{"@context":"https://schema.org","@type":"Organization","name":"Acme"}</script>. Related row: AR-READ-08 (JSON-LD on key pages). The Vercel guide says the study did not measure an improvement in accuracy or completion from JSON-LD. The Verify Kit check json-ld tests JSON-LD.

### Does JSON-LD help agents?

The spec says agents can parse facts from it, but the studies did not measure an accuracy gain, and markdown converters may drop script blocks. Add it where it is accurate and repeat critical facts in visible text.
