Elapsed Time Parameters

These parameters are generated and maintained by the Webtrends analysis process when you enable Visitor History. For more information, see “Visitor History Parameters.”

WT.vr.fvd

WT.vr.fvd=DaysSinceFirstVisit
Identifies the days since the visitor’s first visit. This is an integer containing the days since the visitor’s first visit. The value is truncated (for example, if 47 hours has passed since the first visit, the value is 1). This parameter is not provided on a visitor’s first visit.

When using this as a measure for the Visitor dimension, use the maximum value.

When using this as a measure for dimensions other than Visitor, you usually configure the average value.

The sum of this measure has no meaning.

WT.vr.pvd

WT.vr.pvd=DaysSincePreviousVisit
Days since the Visitor’s Previous Visit is an integer containing the days since the visitor’s previous visit.

This parameter makes most sense when used as a visit filter. This parameter is not provided on a visitor’s first visit.

When using this parameter as a measure for the Visitor dimension, use the maximum value. When using this parameter as a measure for dimensions other than Visitor, you usually configure the average value.

The sum of this measure has no meaning.

WT.vr.pvdb

WT.vr.pvdb=High/Moderate/Some/Low descriptor
Classifies days since the visitor’s previous visit into one of four categories. This parameter is non-numeric and is used as a dimension.

You can change the number of categories by editing the vrbucket.ini file. By default this file is configured as follows:

[PVDBValues]
High = 4
Moderate = 8
Some = 12

The following table describes the meaning of the default values:

By default, the maximum number of days for Some is set to 12. Any visitor whose last visit was more than 12 days ago is assigned to the Low Recency category. Recency is to the number of days since a visitor’s most recent visit.

Example 1: Adjust all of the ranges in vrbucket.ini to:

[PVDBValues]
High = 7
Moderate = 14
Some = 21

Example 2: To create two buckets (for example, High/Low), change vrbucket.ini to:

[PVDBValues]
High = 4
Moderate = 4
Some = 4
The result of Example 2 is:
High is < 4
Low is > 4

WT.vr.ppd

WT.vr.ppd=DaysSincePreviousPurchase
Identifies the days since the visitor’s previous purchase. This is an integer value.

This parameter is typically used as a visit filter. This parameter is not provided until the visitor makes the first purchase and does change on every hit that a purchase is made after that.

When using this parameter as a measure for the Visitor dimension, use the maximum value. When using this parameter as a measure for dimensions other than Visitor, you will usually configure the average value.

The sum of this measure has no meaning.

WT.vr.lat

WT.vr.lat=VisitLatency
The Visit Latency is the number of days since the visitor's first visit (WT.vr.fvd) divided by the number of visit intervals (WT.vr.vc). It gives an indication of the average elapsed time between visits. This parameter is not provided on the first visit.

When using this parameter as a measure for the Visitor dimension, use the maximum value. When using this as a measure for dimensions other than Visitor, you usually configure the average value.

The sum of this measure has no meaning.
