Is Bing Losing Its Wow Factor?

bingBing, the shiny, new search engine that Microsoft (s msft) launched this summer, may be starting to lose its luster. Its U.S. search market share dropped to 8.5 percent in September from 9.6 percent the prior month, according to analytics firm StatCounter. The decline isn’t limited to the U.S., either. The search engine’s global market share dipped slightly to 3.3 percent in September from 3.6 percent the month before. This likely isn’t sitting well with the folks up in Redmond, since Bing was created to lure users away from rivals Google (s goog) and Yahoo (s yhoo).

While Bing was slipping, Google’s slice of the U.S. market rose to 80 percent in September from 77.8 percent in August. The search juggernaut holds 90.5 percent of the global market, which is largely unchanged from last year. Yet Bing isn’t alone in its drop — Yahoo’s share has been shrinking since July. As of last month, Yahoo’s U.S. share declined 9.4 percent from 10.5 percent in August and dropped globally to 4.4 percent from 4.8 percent. Looks like Microsoft may want to start whipping up some new commercials.
