Yes, Google’s dominance extends beyond the desktop. Today, market research firm M:Metrics unveiled its latest rankings of the most popular mobile web destinations in the U.S. and Britain, and Google sits atop both lists.

That said, the Mountain View outfit is significantly more popular in the States than in the UK. This past April, according to the study, 62.48 per cent of U.S. smartphone users visited Google domains, compared with 30.94 per cent of UK users.

Google has topped M:Metrics’ rankings since they were first introduced in March. In the U.S, the company's most visited mobile domain is its search site, followed by Gmail, Blogger, and YouTube, the video download service it purchased in October. More than 2 per cent of users visited YouTube - a hefty haul for mobile video.

On the M:Metrics U.S. list, Yahoo! ranks second, reaching 33.54 per cent of smartphone users, but it tumbles all the way to number nine in the British rankings, at only 10.97 per cent. In Britain, the runner-up is Orange (21.68 per cent), followed by the BBC (20.90) and Microsoft (17.75).

Predictably, Microsoft is third on the U.S. list, just a hair behind Yahoo! at 33.36 per cent. It’s followed by mobile destinations operated by AT&T, Time Warner, Walt Disney, and News Corp.

Reaching nearly twice as many users as its nearest competitor, Google’s dominance on in the U.S. mobile market mirrors its supremacy in the lucrative desktop search market. According to research firm Hitwise.com, Google handles 65.13 per cent of all U.S. web searches, followed by Yahoo! at 20.89 per cent.

The latest rankings from Alexa.com have Google as the web’s third most visited destination, behind Yahoo! and MSN – but that doesn’t include YouTube hits. If YouTube is included, Google takes the top spot.®
