You can also attack it at the source, the DNS server. Rather then
setting two separate DNS entries, set one up as an 'alias' of the other.
The search engines then know that both these DNS strings are really
the same thing and don't divide them. I believe this is called a 'C'
entry in the parlance of DNS servers.

The Fusion Authority (a publication of the House of Fusion) had an
article 'Making Google Pay' describing this a couple of issues ago.
