Adsense limits the channels to 200 and I have more sites than that. I need to track my earnings from say 400 or more sites using one adsense account. I want to be able to list the sites and see the earnings for each and other stats... Any recommendations?
You can use Google Analytics in each web pages of your websites to track the navigation. Try with it and see if helps. Advertisers(Adwords, too) use Google Analytics to track successful conversions of clicked ads.
