It used to be easy to do this -- just find an affiliate product, get some PPC ads, and then see if it sells. Google hasn't allowed this for a while, of course. Yahoo used to, but it seems that Bing does their advertising now, and from what I understand, they won't allow it either. (Is that right?)
Facebook doesn't seem to allow it either.
Does anyone have suggestions on how I might do this relatively quickly/easily? I'm not even looking to make a profit. I just want to do some quick tests.
(Btw, the few second tier PPC companies I've tried seemed like complete rip-offs. I know some people can get these companies to work for them with a lot of patience and testing, but for my quick testing purposes, I can't imagine they would be much good.)
