Dear, I have a newborn fanpage on niche: fitness, build muscle for MEN, and want to build it up. But I don't know if buying post/share from a reputative fanpage will outweigh Facebook ads. Because so far, I just stick with facebook ads and have got very good results, but now I want to make some experiments to see which one really works better. In case, could any of you suggest some good places to buy post/share from fanpage (not direct contact since there're tons of such fanpages outside, I'm looking for a market place like: buysellads where people list their fanpages for such services). Any answer here would be appreciated, Thanks all!
