Hi,
Basically one of the main keywords I'm aiming for is 'eco tours'.

The new domain I've just purchased is "eco-tours.co.uk" and our current address is "ecotourdirectory.com"

I'm not trying to trick the search engines. Just make it easier for people to find our directory. I know that I can't increase pagerank becuase I'm not actually hosting a site at ecotours.co.uk.
