Create a custom targeting audience with Audience Builder
A step-by-step guide to creating a custom targeting audience (formerly known as Retargeting) in the Anonymised Audience Builder. For the creation of a regular (targeting) audience, please refer to Create an audience segment with Audience Builder.
You must also ensure that the Anonymised marketing tag on the domain upon which the custom event will take place is configured to run retargeting - see tag implementation. We recommend customers setting up a custom segment for the first time speak to their Customer Success Manager or support.
The Audience Builder menu collapses to provide more screen space to the feature screens, please click on the icon (->) to expand the menu and its options.
