Is your schema markup valid?
We fetch the exact URL you enter and validate every JSON-LD block on that page against schema.org and Google’s rich-result requirements: exact errors, warnings, and fixes.
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 every JSON-LD block on any page you point it at.
We fetch your page
Paste any URL: a homepage, blog post, product, or docs page. We fetch that exact page's public HTML, following redirects.
We parse every JSON-LD block
We extract all structured data on the page, 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.
You get exact fixes
A schema-health score, a per-type breakdown with the precise errors and warnings, and priority actions ranked by impact.
