Ad tracking solutions?

Greetings to all,

I like to be as scientific as possible with my marketing, and I've done various forms of testing and tracking over the years. But I've never found a perfect solution for doing so, and frankly have not reached the level of sophistication that I require.

I'm looking for a comprehensive ad tracking solution that can track each individual ad or marketing initiative, all the way through from click to sale. Including opt ins, popups/unders, etc.

Basically, I need an airtight system that tracks every possible "conversion point," without losing the visitor anywhere along the way. I also want to be able to track PPC performance down to individual keywords, as opposed to just overall campaigns.

So far, I haven't been able to find a program that does all this, which frankly I find very surprising. Although I will admit I am not a technically inclined person, so I could have misinterpreted one of the programs out there.

If such a program *does* exist, I'd be most grateful if someone could point me in the right direction. And if not, I'm open to paying someone to create such a system for me, so feel free to contact me if you or someone you know is up for the task.

Thanks in advance!
