Multiple Domain Names

how best to handle

[aust29]

Hi I am new to this site, and am on a very step learning curve.

I own a single site with the .com, the com.au, co.nz etc

My question is I believe rather than redirecting or web forwarding, there is another way wherby the url will stay the same as per entry.

Is this classed as coping, will this effect my google ranking.

The domains will most likely be considered duplicates of each other. One of the domains will be indexed, the others ignored, as it should be.

I remember, that somwhere Matt Cutts said, that site will not be penalized for duplicate content if it has different (Oh sh&t, I forgot the name for that last part of domain name, but it's like .com, .lv, .net etc - you got the idea).

Sorry I can't find that link right now, where it's written.

You should watch for duplicate content on domains like www.example.com and example.com (use htaccess to do permament redirect).

The duplicate content filter isn't really a penalty. It is in place to keep identical, or nearly identical, sites down to one spot in the index.

The canonical domain name issue is really only a problem when the two similar domain names are owned by different people, which is rare.
