What do you mean by fraud sign ups? You mean they sign up bu tnever do anything? Explain a little more about the sign up process and waht happens after it and maybe I can help.
Ive used all the main ppc's and a few lesser and Google was by far the best performer, followed by Yahoo then Miva. I wont even bother talking about Goclick........Wooooo.......just stay clear!
Google coverted at about 60 per 100 clicks and 95% were genuine. These figures decreased as we go to Yahoo and Miva.
