Google Rich Results Test vs StructuredValidator

Google Rich Results Test is a free web tool for checking structured data and identifying rich result types a page may enable in Google Search. You can enter a full URL or paste code, then rerun the test. It accepts JSON-LD, RDFa, and Microdata, and can render JavaScript. Testing uses either a smartphone or desktop user agent, with smartphone selected by default. Results report structured-data errors and suggestions, identify detected result types, and show relevant rendered source code in an explorer. Some types receive previews for possible Search or Google Assistant appearances, including desktop and mobile layouts where available. Results can be shared through browser links without permissions; test state and code are saved, while shared links and bookmarked history remain available for approximately 90 days. Anonymous testing needs no Search Console permission, but pages and resources must be reachable publicly. A tunnel can expose local or firewalled pages. Preview output is not guaranteed to match the eventual Search result.

StructuredValidator is a free web tool for checking structured markup, with validation focused on JSON-LD. Paste JSON-LD or HTML to see results as you type. It detects Microdata and RDFa in pasted HTML, but validates JSON-LD only. Checks cover JSON syntax, contexts, types, property names, value formats, @id references, and required or recommended properties for supported rich-result features. The URL tool fetches public HTTP or HTTPS pages, extracts JSON-LD from server HTML, and validates it in the browser without rendering JavaScript. Fetches allow four redirects, eight seconds, 2 MB per page, and 12 requests per minute per visitor. A comparison view places two schema implementations side by side to show differences, missing properties, and coverage. Rich-result preview and API access are available. Validation history and preferences stay in browser storage, and the service says it does not retain validation data on its servers. Optional AI suggestions send markup and errors to an AI provider under that provider’s retention policy.
