In Google Webmasters Tools you can easily set a generic domain (such as .com) to target a specific country. Is there anything similar for Yahoo?

I am placing as #1 for my keyword on yahoo.com but that is of little use since it is a local keyword and I don't even place on the first page on the local version of Yahoo due to it being a .com instead of the country .tld.

.coms will rank internationally but you should try for some local links

Thanks for your reply AussieWebmaster , well I am aware that .com targets internationally but I want to target one of my website to US so should I go for .US domain name?

no .com is fine... look at the hosting location to get you lift
