Yahoo! Has expanded the reach of its popular Yahoo! OneSearch service even further, to the Mobile Web in the United States.

The service reinvents search and offers consumers exactly what they want on their mobile phones, instant answers. It was initially launched in Yahoo! Go For Mobile 2.0 and is now available for over 85 percent of the mobile phones through the mobile web as well as trough the gamma version of Yahoo! Go For Mobile 2.0.

"Yahoo! oneSearch has already started to change the mobile search game by fundamentally improving the way consumers' access and use the Internet on their mobile phones," said Marco Boerries, senior vice president of connected life, Yahoo!. "Consumers that have tried oneSearch love it, telling us it's easier and more helpful than any other mobile search services they've used. We are delivering the results consumers want with just one search, not a list of Web links."

It was designed to enable users to find what they are searching for as quick and convenient as possible, by providing only relevant results right on the page. Yahoo! OneSearch on Yahoo!'s mobile web site also includes sponsored search results and advertisements for further extending the reach of its advertising services onto the mobile environment and enabling advertisers to reach consumers on their mobile devices.

Users will be able to click an ad to be directed to the advertisers' mobile web sites where they can get even more information about offerings or contact details. The service will be released in other country and language versions over the following few months.
