I am currently adding some Schema.org properties on a website and in order to validate my work, I am parsing all pages in Google’s Structured Data Testing Tool. Everything is fine except for one thing, it displays for every page a message saying Unspecified Type even though it mentions 0 errors and 0 warnings!
By clicking on it, you can see where the error is located in the document, and it shows the OG tags I have filled. It displays the type «og:website» but still declares the type is not recognized.
You can check this line is present and read by the tool:
<meta property="og:type" content="website" />
When I check the pages with other tools specifically related to OG tags, I have no warning at all.
I thought maybe a wild invisible character prevents the parsing of this data, but it does see the value …!
What is wrong in my code? Should I worry about this when this tool is not made to specifically validate OG tags?
