Schema.org Markup Validator
This is a placeholder documentation page for the validator.
This service will validate Schema.org-based structured data embedded in web pages.
Features
- Extracts JSON-LD 1.0, RDFa 1.1, Microdata markup.
- Displays a summary of the extracted structured data graph.
- Identifies syntax mistakes in the markup.
It is based on the tool previously known as the Google Structured Data Testing Tool (SDTT), and is provided by Google as a service for the Schema.org community.
Notes
It can...
- Fetch pages from URL, or validate markup provided directly.
- Extract structured data injected by Javascript, e.g. by widgets.
- Combine JSON-LD from script elements, alongside data the HTML attributes defined by RDFa and Microdata.
- Apply some heuristics for cases where markup provides text values when an entity is expected.
Limitations
- The tool is focused on Schema.org. In the case of JSON-LD, this means that it will not fetch or interpret other @context URLs.
