What this tool checks
Inspects JSON-LD found in the initial HTML response and reports detected schema types and parsing errors.
How it works
The checker evaluates server-returned markup, so client-only injected data may not appear in the result.
Common mistakes
Structured data must match visible content. Do not add fabricated reviews, ratings or FAQ answers.
