Frequently asked questions

What does this validator check?

It confirms the JSON parses correctly and that each entity has the required @context and @type keys, flagging structural problems. For full rich-result eligibility, also test in Google's Rich Results Test.

Does it verify every schema.org property?

No — it checks JSON validity and the core JSON-LD structure. It does not enforce every property requirement for a specific schema type, which varies by rich-result feature.
