I have a client that is ranking in two different English TLD's. How can I specifically try to increase the keyword rankings on one of the TLDs without creating a new site? For example, my client is ranking for "web design services" in US and the UK. How can I increase the rankings for just the UK? Is this possible? Would building links from .uk websites help a lot? Just curios. I know creating a TLD site would be the best route, but wanted to see if there is another way as well. Cheers!
