Cnet: ComScore’s February data found Google remaining the website visited the most often; it had 186.6 million visitors during the month. It was followed by Microsoft Sites (174.4 million visitors), Yahoo sites (173.5 million visitors) and Facebook (158.6 million visitors).
Among the sites growing most rapidly was Pinterest, which increased its visitors 52 percent between January and February. MySpace also experienced a resurgence in popularity, jumping from 50th on the list to 42nd. Not surprisingly, the IRS saw a large increase in visits as people began doing their taxes, and many Super Bowl advertisers also saw traffic spikes.
