After a couple months of underwhelming growth, Microsoft’s search engine Bing actually lost U.S. search market share in September, according to data from Experian Hitwise.
- Bing dropped to processing 8.96% of all U.S. searches in September from 9.48% in August.
- Yahoo (YHOO) slumped too, sinking to 16.38% from 16.96%.
- Google (GOOG) advanced to 71.08%.
Standard disclaimer: This is one set of data from one source. Moreover, comScore tends to be the search stats source the industry prefers — not Hitwise.
But even still, this is a lousy — and, yes, slightly embarrassing — outcome for Microsoft (MSFT), which committed $80 million to marketing Bing when it launched just a couple months ago. (In June, Microsoft CEO Steve Ballmer said he would spend as much as $11 billion on search. We said he shouldn’t.)
