For example...
I have 3 sources of traffic: A, B and C. I'm an affiliate of sponsor X and my affil URL looks like
www.sponsorx.com/?eurabia
Now... let's say for simplicity the traff from all 3 comes to my site Z. There I can obviously measure how much came from where. But then I'm sending it all to
www.sponsorx.com/?eurabia That's where the problem comes up: how will I know what conversion each of my traffic sources has?
The sponsor does not have an option of putting "sub" tracking variables into the URL.
So what are my choices?
