Schema Markup Checker & Explainer

Why plain-English schema review beats validators

Validators tell you the JSON parses; they don't tell you the markup is useful. A LocalBusiness block with no phone or address validates perfectly and does almost nothing. This checker reads your markup the way an SEO should: type → facts → gaps.

• Invalid JSON-LD is silently ignored — one stray comma and Google skips the whole block, with no warning anywhere. Rich results just… never appear.
• The money types for local/service businesses: LocalBusiness (map pack), FAQPage (expandable results), Article/BlogPosting (bylines & dates), Product (stars & price), BreadcrumbList.
• Missing fields cost features: Product without offers gets no price snippet; Article without datePublished loses freshness signals.
