Quantcast Cookie Matching Service Tag Setup Guide

When using this tag with utag version 4.50 or later, you must set the utag.js always_set_v_id setting to true. This setting ensures that the visitor ID is available for cookie synchronization. For more information, see the utag 4.50 release notes and Considerations for tealium_visitor_id when upgrading to utag 4.50+.

The Quantcast Cookie Matching Service associates the Tealium anonymous ID cookie with the Quantcast visitor ID.

Tag Tips

• If left blank, Tealium Account and Tealium Profile are populated automatically with the current account and profile.
• Use mappings to override standard config values.

AudienceStream Setup

This tag sends a server-side event once per session for each visitor with an event attribute named quantcast_id. Use this attribute to create a visitor attribute of the same name to use with the Quantcast Audiences connector.

To set up the Quantcast ID in AudienceStream:

1. Create a string event attribute named quantcast_id.
2. Create a string visitor attribute named quantcast_id with an enrichment to set the value from the event attribute.
3. In the Quancast Audiences connector, map the visitor attribute quantcast_id to the parameter Quancast Cookie User ID.
