What is JSON-LD?

JSON-LD is a way to write structured facts inside a page so software can read them without guessing from the layout.

Published 24 August 2026

JSON-LD is a format. You put a block of labeled facts on a page — name, URL, telephone, sameAs links — and parsers can lift them without scraping the slideshow.

What good JSON-LD does

It matches the visible page. If the footer says one name, the JSON-LD must say that name. It points at real identifiers. It does not invent a second company to chase extra keywords.

What bad JSON-LD does

It stuffs every synonym. It marks a local firm as a global brand. It adds a Wikipedia link that does not exist. That is how you teach a model two firms and then wonder why the answer is wrong.

On AI Verified, the human page and the /v/{hash}.json twin stay in sync on purpose. The JSON on this site is the file. The JSON-LD in the page is the labeled copy of that file.

Read why this exists. Check a name in the registry. Or start with a free check. Gold is $297 a year after the website is proved.

Is JSON-LD the same as a public file?
No. JSON-LD lives in a page. The public file is its own URL. Use both.

Should I hide extra keywords in JSON-LD?
No. If it is not on the page, do not put it in the graph.
