Two names for one site - best method?

[kapow]

We have a few customers who want more than one name for the same site. (I don't like doing it but sometimes they insist).

e.g. a site with two names:
- www.brandname.com
- www.keyword-keyword.com

(lets not get into the whole keyword or not keyword argument here). My qestion is about how best to set up a multi-name site without problems with link-pop or dupe-content.

One option is a '301 permanent moved' in the .htaccess of one of the sites so a person can type the name in and is redirected (in a search engine friendly way) to the main name/site.

I set up a site recently with a 2nd name simply parked on the first name. Now both names show a Google PR of 4. I don't like this approach because my client arranged a couple of links to one name while I arranged lots of links to the other name (a mess).

However, the .htaccess approach means that Google should understand the search engine designated name.

hi kapow,

i would favor the 301 solution in this case. then it's no duplicate content but still accessible.
