Time to divulge a real secret about the power of Plus in promotional activities. First, look at my profile in the following screenshot. As I write this, I have 4816 members in my circles, which has generated a total of 1215 people adding me to their circles (meaning they can see my posts).
The Have Ralph in circles (insert your name) is the only thing that really counts for marketing reasons on Plus. They are the primary viewers of your posts and, as we will see in just a moment, the gateways to a lot more people.
"But, whoa!" you say,"1215 is pathetic—you can't sell nothing if that's all you're reaching."
Well, gee, I did that ...
