Seeing non-www in yahoo results - good or bad?

[DavidS-282061]

My site ranks for both domain versions but more non-www than www -

Should I make it one or the other?

How do I tell Yahoo to just choose one?

Ehh?

You must do a 301 redirect from non-www to the www version.

I think this post will help you (http://www.seomoz.org/learn-seo/canonicalization)

Check out my answer here: http://www.seomoz.org/q/block-an-entire-subdomain-with-robots-txt

It will show you exactly how to send all traffic to either your www or your non-www version, which you should definitely do in order to get all the authority your inbound links are bringing you.

If you use a server running IIS as an example it's very easy to redirect from the www. subdomain to the root domain or vice versa.

You should probably redirect to the version that currently holds the most authority and rank. The MozBar can help you establish which one this is.
