how to get traffic to my facebook app inside/outside the facebook. though i have read a lot and have come to a conclusion that inside the facebook one can get traffic via creating a group or fan page, using the social plugins, Graph API, widgets, FB Ads, subscribe button, RSS Feed, etc.
and outside the facebook, as i have understood, the main way to get traffic to facebook is to be active in forums, blogs.
did i got it in a right way? or am i on a wrong way researching this absolutely new filed for me? plz, help me understand
and one more question: does all that offers the facebook promoting guideline account as a whitehatseo?

thanks in advance
