On the other one we had a button they could click and it would produce an inbound call to our team. We were excited about this, but we didn't get many calls and the ones we did get just hung up or were confused about what we offer (even though we could not have been more up front and clear in our ad). On the former campaign (the one where we would call people) it was just bad quality all around.
Has anyone had any success with these types of campaigns? Maybe it's the wrong niche for this sort of thing? What kind of mobile campaigns have you had success with?
