Page View Statistics show the number of Users Session stored in your database. A User Session Is an estimate of unique visits to your web pages. If a person goes to one of your pages, then immediately visits several other pages on your site, the User Session numbers will only increment once. However, if the leaves your site then comes back several minutes later, the count will be incremented again.
These statistics can be far more valuable than simply "Hit Counts," which make it very difficult o know how many actual visitors are viewing your page.
Note that these numbers only represent the number of visitors that have visited at least one web page that has the AddWeb SiteStats LIVE code on it.
