Advertising is all about the number of touches sometimes. Just because they didn't say they were coming from facebook ads it may have been a combination of advertising that included facebook that would move a customer in your direction. We have seen a lot of success with facebook and linkedin advertising when trying to get a small group of doctors to attend live events. It may not make up the bulk of our registrations but when trying to reach a small niche audience we've found every registration counts and facebook lets us do that in a cost effective way.
