How to achieve top rank at YAHOO region search? sg.yahoo.com

[sharm]

Hi everyone.

I'm currently residing in Singapore and so is my personal training business, I'd like to find out about the ranking for region search in YAHOO!.

Ok, i know that we can 'compete' to get high ranking at www.yahoo.com, but if I want to concentrate and get top ranking in the Singapore search only (sg.yahoo.com), how do i do so?

My server is located here in Sanfrancisco (USA), and my domain name is a 'dot com', and NOT 'dot com dot sg' - www.guruFITNESS.com

I have another website (clubFITT.com) and it is number one in rank if i do a search ('personal trainer') at sg.yahoo.com.
I have the keyword 'Singapore' all over my site. Maybe that is why I get a good ranking at sg.yahoo.com

Now that I have this new website, I'd like it to have a high ranking too, but I'm unsure how to go about having a good ranking at sg.yahoo.com

What are the things that I can improve to get a high ranking here? Is it the same as the global search?

Please excuse me if a question like this have been posted before, if there is, do let me know the thread so that i can read from there :)

Thank you,
