Summary  
This chapter explains how to define and manage three types of user segments—predefined (core), user-specified (custom), and similarity-based (lookalike)—by combining attributes, behaviors, and source audiences to refine targeting strategies.

General domain of usage  
Online advertising (Google Ads)

Keywords capture intent, but audiences capture people - **their interests, behaviors**, and **purchase readiness**.

In Google Ads, **keywords** show **what** a person is searching for.
**Audiences**, on the other hand, show **who** that person is.

By combining both, advertisers can reach the right people with the right message.

### How Audience Targeting Works
1. **Select Audience Type** → Core, Custom, or Lookalike;
2. **Apply at Campaign or Ad Group Level** → adjust for broad or narrow targeting;
3. **Layer with Keywords** → combine search intent and audience identity;
4. **Add Exclusions** → block irrelevant or unqualified users.
