# Build Your Audience

This section is a core component of the Audience module that allows you to create and define your Audiences. It sheds light on several key topics that help you to create your audience, categorise them using tags and structure them in folders. You can further define your audience by applying attributes such as [Events](/articles/segment-customer/apply-attributes-to-your-audience#events), [Profile attributes](/articles/segment-customer/apply-attributes-to-your-audience#profile-attributes), [Calculated attributes](/articles/segment-customer/apply-attributes-to-your-audience#calculated-attributes), [Consent](/articles/segment-customer/apply-attributes-to-your-audience#consent), [Marketing preferences](/articles/segment-customer/apply-attributes-to-your-audience#marketing-preference) and others. After applying the attributes, you can check the estimated audience size and make better decisions. Finally, you can activate the Audience by linking it to a destination immediately or later.

The following are the key topics in this section:
