Is your schema markup valid?
We crawl your site and validate every JSON-LD block against schema.org and Google’s rich-result requirements: exact errors, warnings, and fixes, site-wide.
Structured data is how engines understand you
Valid schema markup earns rich results in Google and helps AI search and answer engines quote you accurately. One broken block can silently cost you both. This free tool validates all of it, site-wide.

We parse every JSON-LD block
We extract all structured data, resolve @graph and @id references, and group it by schema type.
We validate against the rules
Each type is checked against schema.org and Google's documented rich-result requirements: required and recommended properties, dates, URLs, and structure.

A schema-health score, a per-type breakdown with the precise errors and warnings, and priority actions ranked by impact.
