http://www.kingofkey.de/kaufen/watch-dogs-key-kaufen-und-download/
I get the message like him...
"Fehler: No rich snippet will be generated for this data, because it appears to include multiple aggregate reviews of many items, instead of a single aggregate review of one item. More information about aggregate reviews."
Please help me because i need the Rich snippets in Google :/
What do i have to do, that Google Knows that this Rating is related to the Item ?
How can i fix this problem?
