I have a question: how do you track your bought traffic?
I mean eg. you buy from 5 traffic provider and run 10 campaigns simultaneously, how do you track the different traffic sources and quality?
My experience is my custom variables are cut from my click URL and not tracked, but I don't know why?
GA and other tracking tools see the original referring URLs ( and not my click URLs ) and therefore I'm not able to attach that to the specific campaign, traffic source.
If I click on my URL containing tracking variables, it's tracked correctly, but giving this URL to a traffic provider using eg. redirects it's not.
Any idea appreciated, thanks!
