Mid-April of this year, Bing reached their all-time high of the Search market share in the U.S. with 20% of the market share. Both, Yahoo and Google experienced a slight decrease with Bing’s gains. These results come from recent analysis of the U.S. desktop search marketplace by comScore. Bing’s success has come mostly at the expense of Search alliance partner Yahoo, making the increase of Bing and the decrease of Yahoo seem as if the two have basically traded spots.

The data compiled by comScore comparing market shares among the Big Three between February and March is displayed below.

According to the above data, Yahoo’s US Search market share is currently at 12.7 percent, and some suspect that’s due to its default Search deal with Firefox which took place over the last couple of months. Google is at 64.4 percent which is a tenth of a point from last month.

According to Investors.com, they suspect Yahoo and Microsoft have revamped their search alliance as Bing gains share of the market.  Here’s what they had to say:

Yahoo and Microsoft announced on Thursday that they’ve restructured their landmark search alliance to give greater flexibility in how search results are presented and how their ad teams work. The restructured deal comes as Microsoft has upped its payment to Yahoo under the agreement, which began in 2009. The restructured alliance comes as Bing for the first time surpassed 20% U.S. search market share.

The online chatter is that Bing’s marketing efforts have been paying off, especially with the Bing Rewards program which allows users to accumulate points that can be redeemed at Starbucks and Amazon as gift cards. Everybody loves those gift cards! Bing has been able to turn even die-hard Google users through their new and innovative marketing tools. Bing has also launched predictive capabilities to attempt to forecast the future in events like the Oscars and March Madness.

What do Google investors think about all of this? Will investors continue to believe Google will push past all these new threats as they’ve done in the past? The stock has struggled over the past year and into this year. Class A shares of the stock are down 4% this year, trailing the Standard & Poor’s 500’s 13% gain over that time.  We’ll just have to wait it out and see what happens. Things should become very interesting.
