Does anyone know if it's possible to find out which leads converted, other than just asking the advertiser? I could check all my emails for people responding to me (because leads usually respond) but that would take a long while and still will probably miss some leads. The only thing I can think of is to iframe the offer and then somehow get your website to send the user's ip or email when they get to the thank you page. Though this will probably hurt conversions since your domain will be fake. Any ideas? I'll buy a script if I have to, but I'd rather just write my own if I had a basic idea or algorithm.
