OK, so far I understand. If I have 6 different PPC site going at any give time, and add the "/?source=adwords or /?source=overture" type of extension I can then see what each site brings into me. I can then calculate the amount of traffic each site brings in, compare that to my sales and determine what my ROI is. Is that correct?
