ok, i'm relatively new to adsense, but i've found out loads of info about it....but i'm not quite sure of the base rules like..... 1. is there a limit to the number of sites i can put adsense on 2. similar to 1., does it matter if those sites are all different niches type like ranging from insurance to baby care to cooking e.t.c . (is there a limit to the number of different niches ) 3. can i have adsense on free hosted subdomains 4. any other thing you like to add keeping in mind i only have one adsense account.
