JSON-LD validity
StructureImpact: Medium
What we measure
Whether the JSON-LD parses, has @context = schema.org, and a valid @type.
Why it matters for AI citation
Malformed JSON-LD is worse than absent — engines log a parse error and downrank trust.
How to fix
Run your JSON-LD through Google's Rich Results Test before shipping.
