I need to track a page with multiple products on it, from multiple affiliate networks. Since I'll be paying for the traffic, I need really sharp tracking solutions to figure out what works and what doesn't. Some networks support pixel tracking, others tid/subid.
I already know about prosper and cpvlab, but I signed up for an online tracking software that looks pretty awesome. I am worried that the people running the software will be able to access my best converting kw. Like I said, I respect their work, that's why I do not want to name the service, but I am fairly new to this kind of tracking, so I do not know what to expect.
Is my paid-for-data going to be safe with this kind of service, or should I opt for a self-hosted solution?
