Research firm comScore recently released their search engine rankings for December 2011 (see table below). As expected, Google holds the first place spot with nearly two-thirds (65.9%) of the core search share. However, these rankings show Microsoft, not Yahoo!, in the second place spot. Microsoft’s Bing boasts a 15.1% share, while Yahoo!’s rating has fallen slightly to 14.5%. As you would expect, Ask holds the forth place spot with 2.9%, and AOL rounds out the top 5 claiming 1.6%. It’s clear that the battle in this arena is for second place… and surprisingly… it goes to Microsoft. However, this is the first time Microsoft has surpassed Yahoo!. Just last month, Yahoo! held the second place spot by over .5%. It will be interesting to see if this is related solely to holiday shopping, or if the trend will continue. Could Bing really be #2? I wonder what Google thinks of all this?
