Fun Facts

• Schema.org was launched in June 2011 as a collaboration between Google, Bing, Yahoo, and Yandex — it defines over 800 types and 1,400 properties for structured data.
• JSON-LD was created by Manu Sporny and Dave Longley and became a W3C Recommendation in 2014 — Google officially recommends it over Microdata and RDFa for structured data.
• Websites with valid structured data can see up to 30% higher click-through rates due to rich snippets like star ratings, FAQs, and recipe cards appearing in search results.

FAQ

Which schema.org types?

Common ones: Article, BlogPosting, Product, Recipe, FAQPage, HowTo, BreadcrumbList, Organization, Person, Event, VideoObject, SoftwareApplication.

JSON-LD or Microdata or RDFa?

JSON-LD is what Google recommends. The tool supports all three formats but flags microdata/RDFa with a suggestion to migrate to JSON-LD.

Does it check Google's requirements?

Yes — Google has stricter rules than schema.org itself (required fields for rich results). The tool marks which fields are schema.org-optional but Google-required.

How do I see the rich result preview?

Google's Rich Results Test (search.google.com/test/rich-results) shows the actual rendered preview. This tool validates structure; that tool shows the visual result.
