Structured Data Checker
Extract and validate a page’s JSON-LD, see which schema.org types it declares, and catch invalid markup that search engines silently ignore.
Prefer JSON-LD
Of the three structured-data formats, use JSON-LD— it lives in one script tag and doesn’t entangle your markup. The golden rule: structured data must describe content the visitor can actually see. Need to add some? Use our JSON-LD Generator.

Frequently asked questions
▸ ▾ Why is my structured data ignored?
Invalid JSON-LD is silently skipped by search engines. This tool extracts and validates it and lists the schema.org types it found.
▸ ▾ Does it detect Microdata and RDFa?
Yes, though JSON-LD is recommended — it's the cleanest to maintain and the format Google prefers.
