a site that i look after has 4 subdomains but the subdomains are
www.subdomain.domain.com
the other sites that I look after all the subdomains are all non www.

this is what I have in my htaccess file for the site that redirects the non subdomains properly

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\.domain\.com [NC]
RewriteCond %{HTTP_HOST} !^www\.subdomain\.domain\.com [NC]
RewriteCond %{HTTP_HOST} !^www\.subdomain1\.domain\.com [NC]
RewriteCond %{HTTP_HOST} !^www\.subdomain\2.domain\.com [NC]
RewriteRule (.*) http://www.domain.com/$1 [R=301,L]

what can I add so that the www subdomains redirect properly.

Thanks in advanced.

I never do it myself, as I have my IT guy do it for me.....but from an SEO perspective this is what you should be do.

Best practice you should point your non-www to your www version of your domain with a 301.

If you have subdomains that point to a main domain, then you take the non-www and www versions of the subdomain point them to your main domain with a 301. You would not point the non-www version of your subdomain to your www version as this would create 2 hops.

If you have your own server you should be able to do it within your control pannel (plesk); some have this ability. I'll look for into this and write a post on my tourism online marketing blog.
