Check id `json-ld` · Readability · runs in the free CLI · pre-release, in calibration

**What we look for.** Whether your homepage has JSON-LD structured data, and how complete it is.

**Why it matters.** Structured data states what you are in machine terms, so AI answers about you don't rely on guesses from prose.

**How to pass.** Add an Organization or Product JSON-LD block to your homepage with name, url, logo and description.

Run it: `npx backwatch your-site.com --pillar readability` and find `json-ld` in the report.
