Searches performed through gained 6% month-over-month while overall “Bing-powered” searches rose 5%. This figure represents a gain of 11% compared to April 2011. The number of Google searches fell an equal 11% during the same period, but only 3% over the last month. Google continues to command a dominant 64.42% of U.S. search volume as April.
