Structured Data Checker
Validate the JSON-LD structured data on your page — Organization, FAQ, Product, Article, and more. Enter any URL and the Structured Data Checker emails you a clear report with the specific fixes to make.
What is the Structured Data Checker?
The Structured Data Checker extracts and validates the structured data on your page. It detects which schema.org types you publish — Organization, FAQPage, Product, Article, BreadcrumbList — checks JSON-LD validity, and flags the high-value types you are missing. The full breakdown is emailed to you.
What the Structured Data Checker checks
- All JSON-LD blocks on the page and whether they parse as valid schema.org
- Which important types are present: Organization, FAQPage, Product, Article, BreadcrumbList, Review
- Missing high-value schema types that AI engines and rich results rely on
- OpenGraph and Twitter card tags for AI and social previews
- Whether entities are cross-linked with stable @id references
- Fabricated or self-serving markup that can trigger manual actions

Frequently asked questions
What is schema markup?
Schema markup is structured data (usually JSON-LD) added to a page so search and AI engines can understand its entities — your organization, products, FAQs, and articles — instead of guessing from raw text.
Which schema types matter most for AI?
Organization, FAQPage, Product, Article, and BreadcrumbList are the highest-value types. Together they help AI engines resolve who you are, what you offer, and how your pages relate.
Does this validate JSON-LD?
Yes. It parses every JSON-LD block on the page, reports which schema.org types are present and valid, and flags what is missing or malformed.
