Penalty for Using a Sub Domain?

Does Google penalise the use of sub domains?

[Duncan]

Will there be a problem if I a create a sub-domain for a site that is already listed with Google, populate it with original content and then use a different domain name to point to it. Could I get penalised by Google for this?

Adding content to a subdomain isn't all that different from adding content to a subdirectory on a site. What you're talking about with "pointing" a domain name is a different story altogether.

Of course, Google won't penalise you if you add new content to your web, does not matter if you put it on a subdirectory, on a subdomain or whereever you want.

But if after adding the subdomain, you want a new domain to point the subdomain, you will have two problems:
1st: If you want to get the new domain listed, you must submit it to the ODP. If you read their rules, you will see that they are not friendly with redirects and similar.
2nd: If you get listed both for the subdomain and for the new domain, google might find that the site is duplicated and penalize you, so beware.

I will make another question, very related:
I'm creating a new page, but i've no domain. I get a subdomain freely by letting the main domain owners put a lot of advertising on my site. I'm not worried about the ad. links, they are always dinamic so can't leak my PR. My question is ¿will my site get listed without problem? It is a new site, but it is in a subdomain.

search google for "<snip>" and look closely at the urls of the results of the first 3 pages. you will see how subdomains CAN work very nicely for you.

The site that dominates those first 3 pages has 2/10 PR and only a small handful of inbounds
