Visitor Tracking Parameters - SDC

Visitor Tracking parameters allow you to track daily, weekly, monthly, quarterly, and yearly unique visitors. The Smartsource Data Collector (SDC) inserts these parameters into the cs-uri-query strings.

WT.vt_tlv

WT.vt_tlv=UNIX Time
SDC generates this parameter to identify the time of the visitor’s last visit. The value is expressed as the number of seconds since 1970 (standard UNIX time), which is calculated using information stored in the third-party cookie value. SDC only sets this parameter at the start of a new visit. On a visitor’s first visit, the value is set to zero. If you disable cookie tracking, this parameter is not generated or passed in the query string.

WT.vt_f_tlv

WT.vt_f_tlv=UNIX Time
SDC generates this parameter to identify the time of the visitor’s last visit. The value is expressed as the number of seconds since 1970 (standard UNIX time), which is calculated using information stored in the first-party cookie value. SDC only sets this parameter at the start of a new visit. On a visitor’s first visit, the value is set to zero. If you disable first-party cookie tracking in the JavaScript tag, this parameter is not generated or passed in the query string.

WT.vt_d

WT.vt_d=1
SDC generates this parameter to track daily visitors for Express Analysis.

This parameter is generated and set to 1 for the first hit from a new visitor for a day.

WT.vt_a_d

WT.vt_d=1
SDC generates this parameter to track daily visitors for Account Rollup Data Sources.

This parameter is generated and set to 1 for the first hit from a new visitor for a day for a given account. This parameter is used in conjunction with Account Rollup Profiles.

WT.vt_f_d

WT.vt_f_d=1
SDC generates this parameter to track daily visitors for Express Analysis only.

This parameter is generated and set to 1 for the first hit from a new visitor when you configure your SmartSource Data Source to use the First-Party Cookie JavaScript. The First-Party Cookie JavaScript generates this parameter and its value.

WT.vt_s

WT.vt_s=1
SDC generates this parameter to track visitor sessions for Express Analysis and Visitor Data Mart.

This parameter is generated and set to 1 for the first hit for a new session. Cookie tracking must be enabled to set this query parameter.

WT.vt_a_s

WT.vt_a_s=1
SDC generates this parameter to track visitor sessions for Account Rollup Data Sources. Applies to Real Time analysis only.

This parameter is generated and set to 1 for the first hit for a new session for a given account. This parameter is used in conjunction with Account Rollup Profiles.

WT.vt_f_s

WT.vt_f_s=1
SDC generates this parameter to track new visitor sessions for Express Analysis and Webtrends Visitor Data Mart.

This parameter is generated and set to 1 for the first hit for a new session. The First-Party Cookie JavaScript generates this parameter.

WT.vt_f

WT.vt_f=1
SDC generates this parameter to track new and returning visitors. This parameter is generated and set to 1 for the first hit from a new visitor.

This parameter is set to 2 if the visitor’s browser does not accept cookies. The First-Party Cookie JavaScript generates this parameter.

WT.vt_f_a

WT.vt_f_a=1
SDC generates this parameter to track new visitors for an account. This parameter is generated and set to 1 for the first hit from a new visitor for a given account.

This parameter is set to 2 if the visitor’s browser does not accept cookies. The First-Party Cookie JavaScript generates this parameter. This parameter is used in conjunction with Account Rollup Profiles.

WT.vt_sid

WT.vt_sid=identifier
SDC generates this parameter to identify visitor sessions for Visitor Data Mart. This parameter is generated on every hit to identify the visitor session.

This identifier is formed by concatenating two pieces of data:

• Identifier: The value of WT.co_f. If WT.co_f is not present on the incoming hit, SDC generates this value. This is the unique identifier that is generated at the time of a new visit. It is 32-character hexadecimal number (0-9, a-f).
• Timestamp: The time when the session began. This is the number of milliseconds since January 1, 1970.

Example:
WT.vt_sid=10.61.19.29-3899933120.29768655.1141069

WT.vtid

WT.vtid=identifier
This parameter is used to identify visitors for Visitor Data Mart. By default, this identifier is provided by Webtrends Data Collection Servers using an in-line JavaScript request for wtid.js at the time of a new visit. Alternatively, this parameter value can come from a custom query parameter or customer cookie.

Identifier: Any alphanumeric string that uniquely identifies a visitor. By default this value is the same as the WT.co_f parameter.

WT.vtvs

WT.vtvs=timestamp
The JavaScript tag generates this parameter to identify visitor sessions for Webtrends Visitor Data Mart. This parameter is generated on every hit to identify the visitor session.

Timestamp: The time when the session began. This is the number of milliseconds since January 1, 1970.
