Campaign Parameter

Use this parameter to associate pages with a specific campaign.


Identifies a specific marketing campaign. Pass this query parameter to pages that you want to associate with a specific campaign. You can specify a numeric or string value.

Note: No errors are logged if you specify multiple campaigns with this parameter, but the Campaign ID string are processed into visitor history as a single string, and are perceived by campaign attribution processes as a single campaign. For example, if you specified:

the campaign value is placed into visitor history as exactly this (a single campaign): Campaign01;Campaign02;Campaign03. It is exported back from visitor history in the parameter WT.vr.rac, and the single campaign appears in reports as Campaign01;Campaign02;Campaign03. All campaign attribution, such as revenue or engagement, is applied to the single string. Furthermore, if the same set of campaigns is specified in a different order, such as:


Webtrends reads it and records it as a new, separate campaign.

Valid Value: Alphanumeric string


WT . mc_id = ad ID

Webtrends Analytics 9 Considerations

If you plan to export Webtrends Analytics 9 report data to a SmartReport, values that are either characters or a combination of numbers and characters work best with Microsoft Excel.

If you enable Visitor History in a profile, Webtrends Analytics reads this parameter and stores it in the Visitor History database. The most recent value of this parameter is made available by Visitor History on every hit as WT.vr.rac.

Webtrends Visitor Data Mart Considerations

Visitor Data Mart uses this parameter to identify Ad events. For more information about the parameter set used by Visitor Data Mart, see the Visitor Data Mart User’s Guide on the Webtrends Documentation page.

Note: WT.mc_id replaces the WT.mc_n and WT.mc_t auto-configuration parameters in earlier versions of Webtrends.
