For the first time, Facebook replaced Google as the most visited Web site in the U.S. for a full week.

Facebook was the most-visited Web site in the country for the week ending March 13, Hitwise said, an online traffic monitor, in a report today. While Google has returned to the top spot, Matt Tatham, a Hitwise spokesman, said grabbing that position for a whole week was a major milestone for Facebook.

For the week that Facebook was number one, with 7.07% of all U.S. visits, Google was right behind the social networking site with 7.03%, Hitwise noted. Rounding out the top five was Yahoo Mail with 3.80%, Yahoo's main site with 3.67% and YouTube with 2.14%.

"One reason for Facebook's success is the features that make it easy to share information and online content with friends," Tatham told Computerworld. "This content sharing is making it the first destination for people going online."

Google has long been firmly entrenched in the top spot. The search giant has been consistently the most visited U.S. Web site since the week ending Sept. 15, 2007, when it surpassed the previous traffic leader -- Myspace, according to Tatham.
