Research firm Comscore revealed its April 2009 survey of US search engine rankings.
And probably to no-one's surprise, Google sites were way ahead of the rest of the search pack, scoring 62.4 percent of searches conducted. The others trailed behind.
Yahoo sites scored 20.4 percent, Microsoft sites a meager 8.2 percent, with Ask Networks scoring 3.8 percent and AOL 3.4 percent. Google improved its score over March 2009 by 0.5 percent.
In all, Americans made 14.8 billion searches of these mainstream engines, meaning that Google sites accounted for 9.5 billion core searches, Yahoo three billion and Microsoft only 1.2 billion. Looks like Wolfram has a way to go to be a Google killer.
