I am currently running three websites using adsense. Since i do this more to be useful than to earn something, i have a subdomain of a free hoster and my websites live in subfolders e.q. mydomain.hoster.com/website1, mydomain.hoster.com/website2, to which i link with .tk aliases.
Is there a way to distinguish adsense income from website1 to website 2?
I tried using custom channels, but somehow this part of adsense eludes me. Can someone shed some light on this?
