Home / Tools / Schema Validator

Schema validator

Check JSON-LD structured data on any page, or paste code, against Google’s rich-result requirements. Plain-English errors, no jargon.

What this validator checks

  • That every JSON-LD block is valid JSON (a single trailing comma breaks the whole block).
  • That each item has a type and the schema.org context.
  • The required and recommended properties Google lists for Organization, LocalBusiness, Product (including offers), Article, FAQPage, BreadcrumbList, Event, Recipe, Video, Software app, Job posting and Review.
  • That URLs such as logo and image are absolute.

For a full audit of a page, including AI-crawler access and speed, run the free site check.
