Structured Data Testing Tool
From Issue #7
Google has a neat tool for testing structured data. Give it a URL and it will find all the structured elements inside the HTML and give you a handy interface for browsing them. It will validate all the elements and show you where you have problems.
I’m still waiting for structured content to have its moment. We know what it is, and we know the value, but I still don’t feel like it’s “tipped,” like headless has done in the last couple years, for example.
