Structured Data Viewer

Structured data helps search engines understand a page and can make it eligible for rich results. This viewer parses your JSON-LD locally, lists every item and its type, and checks a short list of commonly expected properties. It is not Google’s Rich Results Test, which remains the authority on eligibility.
