Structured Data Checker
Fetch a page, inspect JSON-LD and microdata, and flag invalid markup or missing structured data coverage.
Why this matters and usage tips
Structured data helps search engines understand page entities and qualify pages for richer result treatments. This checker gives you a quick audit of the markup currently shipped on a page.
- JSON-LD: often the preferred format because it is easier to maintain outside the visible HTML layout.
- Microdata: still appears on many templates and should be reviewed for missing
itempropvalues or incorrect item types. - Validation: one malformed JSON block can invalidate markup that powers rich results.
- Coverage: compare the output against the schema types your templates are supposed to emit.
Steps:
- Enter the full page URL and run the checker.
- Review each JSON-LD block and fix any invalid JSON before publishing.
- Inspect microdata items to confirm the expected
itemtypeand property set are present. - Update templates or CMS fields when required schema properties are missing or inconsistent.
