- 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.
