Google leads the top five search engines in the U.S. for share of searches, according to data released by comScore.
In Febuary, nearly 10 billion "core" searches were conducted in the U.S., which accounts for a 6 percent decline from January search activity. Core searches are defined as those searches performed on the five major engines: Google, Yahoo, Microsoft, AOL, and Ask, plus across partner sites and channels.
