You have linked your blog or website with your Google+ profile and in search results it is showing your face and your name but not showing number of Google+ in circles details, that how many have you in their circles. you can see in picture below
The problem might be that your circles is less than 20 or something, it will show when your circles increase from at least 20 nos. It will show automatically.
I learnt this from my experience only and I think that this might be only the reason.
