I am thinking about going for the pro version of this tracking script. Can anyone answer these questions? 1. Can it track all your sites or only the site where it is installed? I have lots of sites but don't want to buy a copy for each site. 2. Can you filter the report to a specific domain, where the traffic came from a specific source? e.g. you want to view stats to mysite1.com that came from domain1.com. 3. Can it help you with the 200 channels limit on adsense? I want to track more than 200 niches! 4. I find the filter screen quite confusing. Do you get used to it after a while? Thanks, Jon
