Just announced today – the Schema.Org Markup Validator (SMV) is now live. The SMV is currently in beta, but is going to be replacing Google’s Structured Data Testing Tool (SDTT). Google originally intended the Rich Results Testing Tool to replace the SDTT, but following backlash about this change Google decided to incorporate validation tooling into Schema.Org to support SEOs as they test their structured data.
Structured Data Testing Tool Deprecation: A History
The SEO community was rocked in 2020 when Google announced that they would be deprecating the Structured Data Testing Tool and replacing this resource with the Rich Results Testing Tool, which had just come out of beta. However, the Rich Results Testing Tool has some drawbacks in comparison to the Structured Data Testing Tool. The SDTT validates all schemas, whereas the Rich Results Testing Tool only supports a subset of Google-approved schemas and does not validate all types of rich results. SEOs were not happy; enter the SMV.
Schema.Org Markup Validator Features
The Schema.Org Markup Validator is based on the Google Structured Data Testing Tool. The service, provided by Google for the Schema.Org community, can validate Schema.Org based structured data embedded in web pages, otherwise known as schema markup. The SMV has the ability to extract JSON-LD, RDFa, and Microdata markup, display a summary of the extracted structured data, and identify syntax mistakes in the markup.
Through a Schema App subscription, you have access to an enterprise level site-wide schema markup testing tool, the Schema App Analyzer, that can further help you analyze your structured data. To learn more about different types of structured data tools, we’ve compiled a list of 70+ tools you might find helpful, including our own.
We’ll keep testing with the new SMV and keep you updated with any errors we happen to run into with the tool.
