Frequently asked
Does this guarantee rich results in Google?
No tool can. We validate that your JSON-LD is well-formed and has the required @context/@type. Google's Rich Results Test checks eligibility for specific result types.
It found my types but flagged an error — why?
Common causes: a missing @context, a node without an @type, or trailing-comma/JSON syntax errors. The block list shows exactly which.
