Schema Markup Validator

Validate JSON-LD syntax, entity types, and required properties locally.

JSON-LD or script markup

This is static analysis of the content you paste. It does not crawl live pages, verify HTTP responses, or replace Google Search Console and official validation tools.

Over deze tool

Parse JSON-LD or a script block and report missing required properties, unsupported types, invalid URLs, and graph-level problems. It goes beyond JSON formatting to address broken structured data reported on r/TechSEO.
