Google accounted for 69.67 percent of all U.S. searches conducted in the four weeks ending Jan. 1, 2011. Bing-powered search received 25.77 percent of searches for the month, with Yahoo! Search and Bing receiving 15.17 percent and 10.60 percent, respectively. The remaining 70 search engines in the Hitwise Search Engine Analysis report accounted for 4.57 percent of U.S. searches.
Bing and Yahoo! Search achieved the highest success rates in December 2010, meaning that for both search engines, 81 percent of searches executed resulted in a visit to a Website. Google achieved a success rate of 65 percent, up 1 percent over the previous month. The share of unsuccessful searches highlights the opportunity for both the search engines and marketers to evaluate the search engine result pages to ensure that searchers are finding the information they are seeking.
Out of all paid clicks to the top 500 retail sites, Amazon captured the majority of traffic, or 12.03 percent of all paid clicks for the four weeks ending Jan 1, 2011. This represents an increase of 51 percent compared with the prior month.

As much as I would like to see the playing field leveled I always take these month-to-month results with a grain of salt. Share of searching eyeballs has to be very difficult to quantify and qualify.
Such as; Google's market share may not be as large as we think when you take into account that many webmasters go to Google to check the position of their websites or those of their clients in search results. In fact they probably perform many searches using different keywords. Many of those same webmasters don't bother doing so in other search engines because they simply don't care where/if they rank in them. That can inflate the search figures quite a bit for Google.
By the same token, to say that Google's success rate of producing a valid result that inspires a searcher to follow through to a website is only 65% may not be accurate either. All those webmasters checking results to see where the sites they manage are sitting in SERPs probably don't bother to click through.
