According to web traffic compiled by Complete.com, the UFC’s web site is the 6th most travelled sports site on the internet.
The only sports sites that have a higher traffic rate are MLB, NFL, NASCAR, NBA, and NHL. Here is a quote from the article.
As of this writing, the UFC is the fastest growing sport in America, with a 106% year over year increase in online interest. The NHL, rebounding nicely from a holdout-cancelled 2004-2005 season, was a distant second with 35% growth.
