What is duplicate content and how can I avoid being penalized for it on my site?
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?
