The correct way to have 2 URL's for the same site.

Don't want to be banned from Google.

Where can I find details on the correct way to have 2 domains point to the same site. I want to be CERTAIN that I do it correctly.

do a 301 moved perm redirect from one to the other or block one of via robots.txt.

Google won't ban for this. They _try_ to pick one of the URLs and assign all the other URL's page rank to it, which means it would be treated exactly as if all links pointed to the one URL.

They don't always succeed--sometimes there will be two duplicate listings splitting the page rank. But the 301 trick should get the URLs safely merged.

I'm with hutcheson that they don't always assign the urls's correctly. I solved it with a robots.txt disallow on one of them and a removal request.

We have 5 parked domains pointing at one of our sites and have never had a problem in Google with this.

Where it gets screwed up is in the second tier of search engines like AV or Fast who don't seem to have the filters to eliminate the duplication. One well know SE has 3 of our sites in the top 10 which are all the same site.

We use one of the largest hosting companies and they just park the domains and point them at your site - don't know how they do it however we have no access to things like robots.txt

Thanks all. We have our domains parked at present, I have heard that this can be frowned upon by Google?

I was actually hoping for some reputable written intructions on doing a 301 redirect? I have heard that if it's not done properly you can be dropped from Google.

In the hopes that someone from *G* reads this, and concurs, my vote goes to using dns alias records for all but one site which in turn is using an address record. This actually *declares* that all the aliases are pointed to a host.

If this *is* the case, it would be really nice if *G* would let the world know as a statement of fact.

I'm interested too. I would prefer to simply park the domain and point it since that wouldn't require a hosting solution (expense) for the second domain.
It seems to me this most often causes problems when the parked domain is a common misspelling and people link to the misspelled version. If it is not a common misspelling then you shouldn't have to worry about people linking to the parked domain.
