I'm having a hard time discerning how many actual people visit my shop. The Admin counter on the first page (Where it says "Counter History for last 10 recorded days Session - Total") will indicate for one day, for example, 645 - 2714. I take this to mean that there were 645 visitors and 2714 page views.
User Tracker module, however, will indicate for the same time period "There have been 2512 page views in this 24 hour period. Total number of users: 181"
Google Analytics will then report, for the same time frame: "Visits: 116
Pageviews: 914"

Any idea why the discrepancies? And who is more reliable?

Thanks

Tim
