What this Schema.org checker validates
This Schema.org JSON-LD Checker audits a single page URL and returns a practical structured-data report for technical SEO. It extracts every application/ld+json block, validates strict JSON syntax, flattens @graph nodes, detects Schema.org entity types, and flags common issues such as missing @context, missing @type, non-absolute URLs, and weak field coverage for Article, Organization, Product, LocalBusiness, BreadcrumbList, and ItemList. Each issue includes severity and a concrete fix, plus a transparent JSON-LD health score to help improve schema quality and rich-results readiness faster.
