Frequently Asked Questions
Is this the same as Google Rich Results Test?
No. This is a local best-effort validator for JSON syntax, schema structure and common fields. It does not replace Google’s own rich result testing tools.
Can it validate all schema.org types?
It can parse and inspect any JSON-LD, but detailed hints are focused on common SEO schema types.
Is my schema uploaded?
No. The structured data is checked locally in your browser.
