I'm thinking of having a go at marketing something on Facebook and maybe Myspace, just to diversify and try something new. It seems like dating offers are popular, what other CPA offers convert well? I guess there is no way to really target the traffic for particular offers, just test a variety of them and see what sticks? I know with a facebook application you can gather some good demographic info that could help target an offer, and I've thought of pursuing that path too but it requires a bit more effort ;-) What kind of scale is needed to generate any kind of reasonable return (maybe $500 in a day)? A few hundred chained accounts? Thousand(s)?
