Segmenting your users into identifiable groups to create personalized Experiences for them.

An Audience is a group of people identified by a set of rules. They are the mechanism by which you show different Personalizations and Experiments to specific groups of visitors. For example, you can create an Audience of visitors who have seen a specific page of your website, an Audience of visitors who share custom attributes in common, and much more.

Creating an Audience

Creating an Audience is as simple as creating an entry of type Ninetailed Audience in your Content Source. Because an Audience is an entry like any other, you can publish and govern Audiences using the functionality native to your Content Source.

When creating an audience entry, you choose to either create an original audience using "Create new audience" or use audience already defined within another content source by choosing "Link Existing Audience." The latter option will use a Linked Audience.

Audience Structure

An Audience consists of a name, an optional description and rules . Rules are the criteria that a user's profile must meet in order to be segmented into that Audience. An Audience is also assigned an ID, typically the ID of the entry itself in your CMS.


You have great flexibility in defining Audiences. In the following chapters, we will guide you through the different options that our Rule Builder has to offer.

Most rules require that your web application makes use of Ninetailed's page, track, and identify events. Some rules can be used when any of these methods are used, while others require specific tracking methods to be implemented. Consult each rule type for further guidance. See also the documentation of each of those events.
