I want to promote my site with some social media. But Ive never did SMM before. For Facebook, do you just pretty much comment on relative groups, with your site? How would you go about finding groups that are relative to your site? What about fans to your page? Also, how do I go about searching groups? I cant seem to find the function. For Twitter, I assume retweets are working best from what I read. What other ways can you advertise on twitter?
