Structured Data Checker

Check for valid Schema.org markup.

About the Structured Data Test

The Structured Data Checker validates Schema.org markup on any page. It parses JSON-LD, flags errors and warnings, and reports rich-result eligibility so broken schema never ships silently.

Valid structured data helps search engines show rich results and helps AI retrieval systems classify your pages and resolve your entities. Invalid schema is worse than none — it erodes trust in everything else the page claims.

Enter any URL to test. Generate new markup with the Schema Generator, then validate here before publishing. Sign in to run checks.

Frequently asked questions

What does a structured data checker do?▾
It fetches a page, parses its Schema.org markup, and reports errors, warnings, and eligible rich-result types. It catches the typos, missing required fields, and type mismatches that silently void your schema.
Which markup format should I use?▾
JSON-LD in the document head. It is Google's recommended format, keeps markup separate from visible HTML, and is what every major validator and AI retrieval pipeline parses most reliably.
Why is my valid schema not showing rich results?▾
Validity is necessary but not sufficient — Google also requires guideline compliance, page quality, and query relevance. Keep schema matched to visible content and re-test after every template change.
Can I test schema without publishing?▾
Yes. Validate markup snippets directly in the Schema.org validator or a code-snippet mode, then run the page-level check once the template ships.
