SEO penalty for "duplicate" content when a site's also accessible via another domain name?
- by tog22
While testing searches for keywords on my site, I notice that a mirror of it at http://a8.8d.344a.static.theplanet.com/ sometimes appears at the top result rather than my primary domain. It looks like this is an alternative address for my server. Will the presence of identical content at this domain and at my primary domain result in a Google penalty? If so, what can I do about it?
Thanks for any help...
