I'm not sure on the answer to your question, but you do not have to track your URLs in this manner.

It will not do your pages any good, as PR is assigned to URLs - which usually corresponds to pages. Where multiple URLs point to the same page, the page ends up with split PR. That's not good.

I am not quite clear about this.
Does it mean that I am splitting my PR if I point/direct my brandabledomain.com to my website at www.keyword-domain.com?
