Hello, So i have around 1,5 year experience with Tumblr (fuck them, never again). Around 8 months experience with Instagram (my main side activity right now). And right now i wanna go into FB game. Anyone can give quick TL.DR about growing FB fan page (is it enough to post pictures from your page account to niche related groups and then inviting them to like your page). I dont wanna start with boosting page posts before i learn how to get atleast some fans without spending $.
