Validation
Structured data must be syntactically correct (valid JSON for JSON-LD) and semantically valid (correct schema.org properties and types) to generate rich results. These three checks identify markup that exists but has errors preventing it from being processed correctly.
Schema JSON Parse Errors
Warning
Structured data JSON is malformed and cannot be parsed — search engines will discard it.
Schema Validation Warnings
Warning
Structured data has schema.org property or value issues that may prevent rich results.
Invalid Schema Types
Warning
Structured data uses schema types that do not exist on schema.org.
Validate your schema markupacross all pages
The audit checks every structured data block for syntax errors, validation warnings, and invalid type declarations.
