Microsoft's BING Search Engine Again Gains Market Share (MSFT, GOOG, YHOO)

Microsoft (NASDAQ: MSFT) is again benefiting from continued gains in BING's market share over competitors. Google Inc. (NASDAQ: GOOG) and Yahoo! (NASDAQ: YHOO) market shares were approximately unchanged over the past month. Microsoft and Yahoo! will essentially grab 28.5% once their search deal is complete given current market shares.

Since Microsoft's Bing was introduced in late spring it has been gradually increasing its market share each month. Some analysts see the "categorization of search results", the "airfare price indicators", and "cash back" features as some reasons for Google and Yahoo! defectors.

Between organic growth of market share, the search deal with Yahoo!, and the general growing of the internet search market Bing could help Microsoft's bottom line in the search world.

And that has been something Microsoft has been searching for.
