Hi, I have created a new social link sharing type service which is gathering momentum and would like to determine what type of advertising I would be allowed to use and which would perform the best. To begin, the pages I wish to display ads on dont have any content owned by myself, instead the page residing at the location of the shared link will be displayed in an IFRAME. I'm guessing, maybe wrongly, that several ad networks wont like this very much, is this true? Secondly, having done a little research I believe pay-per-impression rather than pay-per-click would suit me better. Can anyone recommend any good pay-per-impression networks that would allow me to use ads on my aforementioned service? Possibly ones which offer $3-4 per 1000 impressions (if this is at all achieveable!) Thanks for your time, -Mike
