I have a website and I am working over its SEO. I have put all required structured data in it as per my knowledge and have also tested it with Google Webmaster's Structured Data Testing Tool and it detects everything fine and all requirements are met.
But back in Webmasters Tools when I go to: Search Appearances > Structured Data it says:
We do not detect any structured data on your site. Structured data helps Google understand the content on your site, which can be used to display rich snippets in search results.
Why is this happening, and do you have any idea how I can correct it?
