Schema & JSON-LD Bulk Validator

Detect every Schema.org type on a page — Article, Product, FAQ, Breadcrumb, Organization… Catch missing required fields (author, datePublished, headline) before Google does.

URLs one per line · max 15

How this tool works

No third-party validator. The server fetches your HTML directly, then parses every JSON-LD block, microdata, RDFa, and Open Graph / Twitter Card meta locally. For Article, BlogPosting and NewsArticle schemas, it also warns if required fields like author, datePublished or headline are missing.

No external API is called. Results are cached for 6 hours per URL.
