How can i prevent googlebot from indexing my suddomains? 1) i have not seen any option in google webmasters for blocking subdomains.(subdirectories/indivisual pages can be blocked) 2)If I use meta=no follow, no idex, then i have to add this to all pages which is bit cumbersome. 3) I am not sure about robots.txt as it does not allow syntax like http:// which is required for a subdomain. Please let me know your views....
