What Our Schema Validator Checks (That Google's Tool Doesn't)

Google's Rich Results Test only checks basic validation. We check for hidden issues that cause Google to reject or ignore your schema.

Syntax Errors & JSON Formatting

Finds missing commas, extra brackets, wrong quotes, and all JSON syntax issues. Shows you the exact line and character where the error is. Google's tool often can't pinpoint these.

Validate JSON syntax

Missing Required Fields

Each schema type has required properties. We check if acceptedAnswer, offers, author, datePublished, etc. are present and correctly formatted. Lists ALL missing fields, not just the first one.

Check required fields

Content Matching Validation

Google REQUIRES schema content to match visible page content exactly. We check if prices, questions, reviews, dates match. This is the #1 reason schemas pass validation but don't show.

Test content matching

Policy Violation Detection

Checks for hidden policy issues: promotional language, schema on wrong page types, hidden content, misleading information. Flags issues Google will reject even with valid syntax.

Review policy checks

Schema Type Appropriateness

Using Recipe schema on a product page? FAQ schema on homepage? We flag schema types that don't match page content. Google ignores inappropriate schema usage.

Choose correct type
