How to track conversions using Google Analytics

[Tehuti]

I have a digital product on my website. When people click "Buy now", they are taken to Clickbank, which processes the payment. The customer is then redirected to E-Junkie, which delivers the product securely. As such, three sites are involved in the process: my site, Clickbank, and E-Junkie.

How do I track my conversions using Google Analytics? I've been trying to figure it out, but it's confusing me so much!

I know I must set up a goal in Analytics, but multiple domains are involved. Can anyone help me, please? Any advice will be appreciated very much.

Thanks, Rhinofish. I've been going through those resources. It's so confusing!

Google says I must put the cross-domain tracking code on all domains, but I obviously can't modify Clickbank's payment processing pages.

Clickbank offers an "Integrated Sales Reporting" feature from within my account, which allows integration with Google Analytics. It allows me to add my Analytics tracking ID, but not the rest of the cross-domain tracking code, so I'm not sure if it'll work.

The cross-domain tracking code asks me to include all domains. I don't even know what ones to include because, to confuse the matter, E-junkie deliver the product via a different domain called fatfreecart.c om or something like that!

So confused!

Has anyone else set up Analytics to track conversions that cross from their own site to Clickbank and then to E-junkie?
