like dp ..can we display ads on a subdomain like www.xxx.mydomain.com ??? i already gotta domain and i need to make it a completely different site with different theme and my site is already accepted by adsense ..so do i just add the code to the subdomain n nothing else ??
Each subdomain is treated as a separate website. Besides as far as Adsense is concerned, they do encourage you to host their ads on all your web pages, the only things they are concern about is the number of adsense placement PER PAGE and that you do display the ads on pages which contains contents which would not be acceptable by them.
I agree with Eddy. I don't see any reason why you could not place ads on the pages in your sub domain.
