URLFAN is an evolving experiment designed to discover what websites the blogosphere is discussing all in real time. It does this by cultivating the content of millions of RSS feeds, parsing billions of pieces of information to make a transparent ranking based on that data. In this way you can discover who's a fan of your URL. Now every website owner can see who's talking about their site in real time and how they compare to every other site on the Internet. There are many websites designed to rank the "traffic" of a website, such as Alexa, however URLFAN is different. URLFAN ranks websites according to their popularity in the fast moving and growing world of RSS feeds. Unlike Alexa, there is no approximating in our ranking system since we're using concrete data to generate the results. Some important factors to note when using Alexa, according to their disclaimer : Alexa only measures websites visited by Internet Explorer, over counts websites like Amazon, and only counts websites visited by surfers using Windows. You can probably guess that as the web shifts from IE/Win setups to competing browsers and operating systems, a more accurate way to to measure popularity is needed. URLFAN is here to provide website publishers with a useful tool in tracking their websites and how their content is referenced by other websites. Registration not required.
