You should have a solid idea of how visitor behaviors change at the end of the work day or on weekends. “Daypart” is marketingese for sections of the day that have different audiences and different audience behaviors. WebTrends’ SDC tag conveniently collects the local time of day for every hit.

When you click on Re-Analyze, you get the warning “Any previously analyzed data will be lost.”

Let’s make that little warning really clear. It means: Should you go ahead with a re-analyze, ALL previous processing will be erased, along with all WebTrends-controlled backups. Your configurations stay, but WebTrends deletes all statistics and all backups and starts analysis over with the earliest raw data it can find.
