I have to say I'm surprised that Clickbank still has no global Pixel-tracking for publishers. This means that you can enter your conversion tracking code or pixel directly into the interface and it would be placed automatically on the merchants success-checkout page. That way you have the perfect tracking mechanism for many traffic sources (all PPC and many PPV). Today you have to ask the merchants yourself to do this or use complicated tracking software. If the CPA-Networks like Azoogle and Neverblue can do it, Clickbank could do it, too. It is a pretty huge competitive disadvantage now (I personally like to run campaigns with the networks mentioned above much better because of that). Hopefully Clickbank will read this and start working on that feature (or say that they already do)
I believe they already have that, check the following out: http://www.clickbank.com/help/account-help/account-tools/integrated-sales-reporting/
Wow! Yes that's it. That's great news, what a coincidence! Now you can track the conversions of your ppc campaigns down to the keyword level directly in adwords, analytics and yahoo SM. Thanks Ripped.
