Can you help with my online identity problem?

My name is Bill Bennett and I live in New Zealand where I work part time as publisher of Reseller News at Fairfax Business Media.  The rest of my time is spent running a business-to-business communications consultancy. I have a web site and a blog, but pretty much zero visability because my name
is:

a) fairly commonplace and
b) shared with a number of people who are far more famous than me.

How bad is it? Last time I checked, I didn’t appear on the first ten pages of “Bill Bennett” on Google. Strangely I come in on page five with Yahoo! Perhaps the most annoying aspect is the other Bill Bennett’s even rate higher than me when I restrict my Google searches to New Zealand-only results.

The biggest problem is the American politician / radio host. I sometimes get his hate mail. There’s also an Australian film director, which was especially tricky when we both lived in Sydney, Australia. (Though I did get a couple of interesting nsfw emails from out-of-work actresses looking for a big break into movies). There’s also a country and western singer, a brace of Canadian politicians and an ancient British comedian.

Using William instead of Bill doesn’t help one bit, nor would changing everything to Billy. It doesn’t help me to brand myself as Bill Bennett the writer (that applies to at least two other Bill Bennetts on the famous list). I do some radio broadcasting, but that’s also useless.

Sadly, my new disambiguation page seems to get more traffic than my homepage.

I’d like to know from readers what I practical steps I can take to raise my online profile or at least rise a bit further up the list.
