subdomains

Does Google like them

[brmmbrmm]

A few months ago I created a site for a client and managed to get a decent ranking. In an attempt to boost this I created a subdomain like www.keywordrich.domainname.com and redirected it to an appropriate keyword rich page on their site. The redirection is done using Lotus Domino virtual domains, not META stuff - not sure if these are the same as 301s that I read about.

These additional pages have not been listed. Any feedback on what Google thinks of subdomains appreciated. I've read mixed comments. Some of my clients using a cheaper service I offer are not even buying a domain but using a subdomain from by business's main domain. Are these likely to get listed?

etc...

They are fine with subdomains
