Here’s a very interesting finding ripped from today’s social media headlines: The Business Insider and other media outlets are reporting that Facebook now accounts for nearly one in four page views on the Internet in the United States.

So claims database marketing consulting firm Drake Direct, which has studied web traffic in the U.S. and the U.K. by analyzing data collected by Compete, a leading aggregator of web statistics.

Just to give you an idea of how significant Facebook’s results are: by comparison, search engine powerhouse Google accounts for only about one in twelve page views.

And Facebook is now closing in on Google when it comes to site visits – with each currently receiving around 2.5 billion visits per month. In fact, studying the trend lines, Drake Direct anticipates that Facebook site visits will surpass Google any time now.

Another interesting finding is that the length of the average Facebook visit now surpasses that of YouTube (~16 minutes versus ~14 minutes per visit), whereas YouTube had charted longer visits prior to now.

These findings underscore the continued success of Facebook as the most successful social media site, even as it has grown to 350+ million users, including more than 100 million in the U.S. with 5 million added in January alone. No doubt, it’s on a roll.
