Google led the U.S. search engine to end the year, collecting 67.3 percent of the search market, clearly ahead of Microsoft's search sites which collected 18.2 percent. Yahoo picked up 10.8 percent while Ask Network accounted for 2.5 percent, and AOL trailed with a meager 1.3 percent, according to research group comScore.
During the month of December, there were 18.3 billion core searches, and Google's collection of websites racked up 12.3 billion, while Microsoft sites had 3.3 billion searches, and Yahoo trailed with 2 billion.
Google's lead is clearly safe at this moment, but the Silicon Valley-based company needs to continue to be vigilant to ensure Microsoft and Yahoo don't continue to steal market share. As more users continue to go mobile with smartphones, tablets and other devices, Google Android and Microsoft Windows Phone have an advantage while Yahoo is left out in the cold.
