Yesterday, the monthly search market share numbers from comScor e (SCOR) were released, showing Microsoft (MSFT) Bing up, Yahoo (YHOO) down and Google (GOOG) maintaining its dominance. In today's release by Experian Hitwise , Bing is up again, from 9.37 percent to 9.7 percent, while Yahoo was flat at 14.57 percent, and Google gave up a scooch of share to fall to 70.95 percent from 71.49 percent. This time it appears to be the vertical searches–such as autos and health–helping Bing, which has been its strategy to differentiate itself from the Google juggernaut.
