Schema Markup Generator
The Schema Markup Generator reads any page, works out what it is, and writes the JSON-LD structured data it’s missing — filled in from the page itself, validated against Google’s required and recommended fields, and ready to paste. Free, no signup required.
Try it nowWhat this includes
- 01
Whether the fields Google marks required for the detected type are present: name, address, phone for Organization; price and availability for Product; author and date for Article. Missing required fields fail Google’s own Rich Results Test, not just this one.
- 02
Fields that aren’t mandatory but meaningfully improve how a machine understands the page: logo, social profile links (sameAs), breadcrumbs, FAQ pairs.
- 03
Whether the schema graph correctly references itself with @id, and whether it conflicts with markup another plugin already emits on the same page — the most common real-world schema bug.
