Unlike many Web pages, the traffic to some sites doesn’t fall over time. A new model of Web traffic shows why. Back in 2005, a group of computer scientists carried out a now-famous study of the way visits to a website fall over time. These guys looked at the traffic to a Hungarian news site and found that it decayed as a power law. This, they said, has a straightforward explanation: the amount of traffic is simply a reflection of people’s browsing habits. They speculated that during each visit, surfers access all the new articles that appeared since their last visit. And since the time between visits follows a power law, the number of people who have not yet seen a story also follows a power law. This explains the observed pattern of traffic.
