Question about mirror sites..

[chance]

Altho mirror sites can be used for good intent, most of the time they are not. So I understand why google is cracking down on them. I am kinda new to this so any input would be greatly appreciated.

What if you have several domain names (not mirror sites by definition of seperate servers.) that all pull up the same page? Is this considered a mirror site?

Example..
http://www.A.com/
http://www.B.com/
http://www.C.com/
http://www.D.com/
http://www.E.com/

When any of the domain names are typed in the url or clicked thru a search engine all will take you to domain "A". However they will maintain thier own domain name.

Example..
type in www.B.com and it will take you to www.A.com.
Once you are there it will remain www.B.com, but all content is taken from www.A.com.(only 1 actual site)

I hope this makes sense ^_^.. if I didnt describe my question well enuff please let me know,
thanks in advance,

Chance

What you need to do is to pick one domain name and make sure the search engine spiders cannot index the other ones--and put a 301 Permanent Redirect from all the other domains to the main one.

If you do it any other way you will get caught for duplicate content and all your sites will suffer the consequences.

hmm may I ask how I add the no index spider code to those certain domain names? since there is actually only 1 site. Also if they are never to be indexed by a spider again then there is really no point to the extra domain names correct? So should I just get rid of them?

Thanks,
