Hi you agree that you have got traffic form facebook.com. But you mentioned without www. I want to say please paste two url on browser http://facebook.com and www.facebook.com and you will go to same site. I mean you will go facebook.com. So here is nothing different which you mentioned http://facebook.com rather www.facebook.com.
They must click your link. Here is proof: http://goo.gl/#analytics/goo.gl/bgTMfm/all_time
