if it doesn't display snippets then the module is installed incorrectly

Hi Alexander,
In my case there is no error showing in google rich snippets testing tools. I have around 12000 products & google rich snippets just shows 2868 products in the list !
->markup is valid. This confirmed by google rich snippets team also.
-> products page ranking is good..for many products my site results is at #1 place in google search results
-> I have checked all products which has got rating & reviews but none of them is showing rich snippets !

Also this list products crawled is decreasing every week !

I am in touch with Danila Struchkov regarding this issue but not getting any clue for this issue.

So that means even if everything is setup correctly it's depends upon google's decision to show your site or not.
