Total unique visitors in 2005: 16008 visitors

Where do these numbers come from?
The statistics rely on visitor information automatically logged by internet provider 1and1.

So what is a "Unique visitor"?
This analysis summarizes multiple page impressions of an individual visitor into unique visits. A visitor is counted only when bringing up more than one page and taking no longer than 30 minutes between individual pages.

Just statistics
