Traffic Log Patterns

On log patterns...

"About 10 years ago, I showed that the popularity of a website's pages followed a power law. Briefly stated, a few pages on a website were extremely popular, a larger set was moderately popular, and the vast majority constituted the "long tail" of low-traffic pages.

Mathematically, the Zipf curve is a straight line on a double-logarithmic diagram, when we plot pages with their popularity rank on the x-axis and their number of hits on the y-axis.

The old analyses showed that this same distribution also described both the number of incoming references to a website from other sites and the outgoing traffic from a company's employees.

Do these findings continue to hold today? The Web is now 2,200 times bigger, so traffic patterns might have changed. I decided to find out.

Page Popularity
The following chart shows useit.com traffic during a recent eight-week period. Each dot represents one page, and the pages are sorted by popularity. The most popular page (the homepage) got 261,024 pageviews.
For the most popular 350 pages, the empirical data follows the theory remarkably well. Thereafter, however, the data trails off and the next 700 pages have less traffic than predicted. Also, in theory, there should have been about a quarter-million additional pages with low traffic, but I simply haven't gotten around to writing that much."   continued ...   (Via useit)
