All my websites do not use www. If anyone types www before the domain (e.g. www.mysite.com) the www is removed using .htaccess (thus becoming mysite.com). I also utilize subdomains on many of my pages. I want to use AdSense URL channels to track stats on my websites, but I want it to track the subdomains and main domains (which don't have any subdomain including the www). I can do the subdomains by themselves, by entering the subdomain (e.g. forums.mysite.com). However, if I enter the bare domain (e.g. mysite.com), it tracks results from not only that bare domain, but also all sub-domains. I don't want that. Instead, I want to be able to track the domain (e.g. mysite.com) without tracking the subdomain (e.g. forums.mysite.com). How can I do it?
