Apparently you cannot include different subdomains in the same google site map. If a site has lots of subdomains, what are some good approaches for submitting them to google? If you have a different site map for each subdomain is there a way to submit them as a group without creating an entry for each subdomin in web masters tools? Thx,
You have to male separate sitemap for each sub domain. Is your site has many subdomain than submit in same account in which you submit main domain.
