Schema Markup Checker
Extracts every JSON-LD block on a page, lists the schema types found, and flags invalid JSON and missing LocalBusiness essentials.
Why it matters

What you get
Extracts each JSON-LD block, validates the JSON, lists the schema types found and checks for the local business essentials, FAQPage and breadcrumbs.
