According to new findings from researcher M:Metrics, Google is the top mobile Web site in terms of smartphone users in the U.S. and the U.K. Is anyone really surprised that Google is the top mobile site?

While I was not surprised to see Google at the top, I was surprised to see the U.S. results after the top three: Google, Yahoo, and Microsoft. I expected to see The Weather Channel slightly higher in the rankings, though it still did quite well. For those of you who don't know, The Weather Channel is considered by many industry insiders to be the breakout hit of the mobile Web. While these numbers confirm that, based on anecdotal evidence, I expected TWC to break the top three.

As for big surprises, I didn't expect to see eBay top lists in either the U.S. or the U.K. I guess there are a lot more mobile Web users out there following auctions on their smartphones than I thought.

As for the U.K., I was amazed at how the carriers dominated the list of top mobile sites. Aside from AT&T and Sprint, the U.S. results were all content or service properties. But in the U.K carriers had a much stronger showing. Granted, there are more nationwide carriers in the U.K. than in the U.S., which probably explains much of this disparity. But these results also show just how carrier-centric mobile Web use is in the U.K. compared with the U.S. Based on these numbers, it would appear that more Americans access off-deck mobile content than the British.

In March, I reported the results from a survey conducted by the Online Publishing Association that showed Americans use the mobile Web more than Europeans taken as a whole. While the British were the biggest users of the mobile Web, Americans came in with a respectable showing. If this earlier survey is accurate, then there may be more Americans using off-deck mobile content. What do you think?
