What is an Audience?
An "Audience" is a group of visitors that you want to be included in your experience, being an experiment or personalization.
Audience Dialog Sections
You can create an audience for your experiment by going to your Experience Summary and locating the Audience section. From within the Audience section, you can add a previously saved audience or create a new audience.
Clicking on the Add Audience dropdown will give you the following options: 1) Templates or 2) Advanced
Important: Note that the audiences listed in the Audience Dialog section are joined in an OR fashion and not AND.
The Templates section allows you to choose from pre-built audiences. This will help you speed up the configuration of your experiment audiences.
This section is where you can create your own advanced audiences if none of the templates fit your requirements. More documentation is available here.
