Google crowned world's most visited site

Google outstripped Microsoft in March to become the world's most visited Web site. The new ranking from Comscore comes in the same week that a British marketing firm named Google the #1 brand, beating out Coca-Cola for the top spot.

Google had 528 million unique visitors in March, up 5 percent from February, according to comScore. Microsoft had 527 million visitors during the same month, up 3.7 percent.

Behind Google's success: It's domination of the search market, of course, with 53.7 percent of all searches on the Web, according to Nielsen/NetRatings. Microsoft trails with 10.1 percent.
