This section covers how to configure, manage, and use audiences
to classify visitors.

An audience is a major classification of a visitor into an archetype
or persona, for example "Developers," "Marketers," or "Jen the wholesaler."
Audiences can be made up of any combination of [signals](https://docs.uniform.app/docs/guides/classification/signals),
[enrichments](https://docs.uniform.app/docs/guides/classification/enrichments), [intents](https://docs.uniform.app/docs/guides/classification/intents),
and other audiences, which allows them to become broad archetypes.

A visitor isn't a member of an audience. Instead, information about
the visitor and the visitor's actions contribute to a score. For
example, if the visitor has triggered a certain signal, that might
add 10 to the a specific audience score. Personalization might be
applied as long as the visitor's score for this audience doesn't
exceed 25.

> **Tip:**
>
> For background information about what audiences are and
> examples of how they're used, see the [classification](https://docs.uniform.app/docs/guides/classification#aggregations-intents-and-audiences) overview.

> **Tip:**
>
> Audiences are useful for customers who don't have a customer data
> platform (CDP). This gives you the ability to assign a visitor to
> an audience when appropriate.
