Hi sorta new to affiliate marketing, I am wondering how I get flash ads particularly those of the 728x90 size. I am currently signed up with CJ, Adbrite and Clickbank but I think only Adbrite shows 728x90 ads and so far none that I have reviewed are flash based. Do I have to let the advertisers come to me or is there a site with these ads?
It seems you are most probably looking for CPM ad networks. These are the sort of networks that have flash ads. They include ads like "click the fart button", "shoot the duck", icon ads, etc. The 2 first cpm ad networks listed here offers this sort of ads that are 728x90 in size. Hope that helps and good luck.
