Maybe we're doing something egregiously wrong with Facebook? Check out our page, www.facebook.com/soulphonicband
There is practically nothing on your page. You haven't filled out your profile, very few pictures, and most of your updates from the past few months are MailChimp postings. Facebook won't work for you unless you put in some work. Try to post at least once a week and make it something interesting. Use pictures that your fans will want to share. It will build your audience over time.
