I suppose it depends on the way your traffic is generated. I'm talking about things that take campaign management and individual surfer tracking a bit further.

Let's say for example a specific program will work with you and provide a postback with a little data, like an ip address, when a specific action occurs (a registration for example).

With some significant tracking on your end done beforehand, you could cross reference that ip with your data and follow the path of someone that actually pulled out their credit card / triggered a goal for you.

Then you'd really be able to pinpoint your most effective campaigns, landing pages, copy, etc.
