How do I add subdomain's sitemap to Google Webmaster Tools?
I have not added them in yet as it takes ages for Google to get around to crawling it and I would like to add the sitemaps as soon as knowing that it is the correct way. BTW... I do not really want to have them separate for stats purposes and that I just wish to get them on Google's search engines.
Would it still work if I add them to my main domains sitemap? i.e. where I would like to place all sitemaps:
www.sm.example.com/sitemap1.php
www.sm.example.com/sitemap2.php
My other subdomains would be like this...
www.sub1.example.com
www.sub2.example.com
- and so on...
