# Visitor "Initial" Parameters

The following list describes several visitor parameters that keep track of the “first” aspects of a visitor’s history with the site. Note that although the parameters use the terminology “first,” all preconfigured objects based on these parameters use the term “initial” (for example, Initial Referrer is the dimension based on `WT.vr.fr`). Webtrends generates these parameters when you enable Visitor History. For more information, see “Visitor History Parameters.”

#### WT.vr.fr

`WT.vr.fr=FirstReferrer` Identifies the visitor’s first recorded referrer. The format is the same as that for the Referring Domains dimension (for example, `google.com`). This is set on the first hit of the first visit and does not change afterwards.

#### WT.vr.fc

`WT.vr.fc=FirstCampaign` Identifies the visitor’s first recorded marketing campaign. The format is the same as that for the Campaign dimension. Only campaigns identified using the `WT.mc_id` parameter are counted. Campaigns defined solely through Webtrends Administration are not used.

This parameter is not provided until the visitor visits with a campaign. At that point the value and parameter are set and will never change.

#### WT.vr.fe

`WT.vr.fe=FirstEntryPage` Identifies the visitor’s first recorded page view. The format is a page URL without query parameters. This is set on the first hit of the first visit and never changes afterwards.
