I run a Clickbank affiliate program ($31 in sig) and I'm trying to figure out how to let affiliates add their Google AdWords tracking code to my thank you page automatically. For example they'd put in affiliateID.dayoff.hop.clickbank.net/?g=trackingcode And then I'd get that variable and somehow store it so that if they do end up at the thank you page (after purchasing the product) - I can place their tracking code into the page. I've just figured out how to do a redirect to another page using php affiliateID.dayoff.hop.clickbank.net/?x=over (there's nothing much at that page now... but if you know clickbank maybe you can understand what I'm going to be doing there... creating a "pre sell" langing page pre-made so affiliates don't have to necessarily make their own.) But how to do this Google tracking deal is a bit out of my understanding... I'd really like to do it though as I think it's an excellent feature to offer affiliates. I'd be willing to pay $10 via Paypal to anyone who can tell me how to do this (so that I can actually do it.)
