What is targeting?

Targeting is the process of selecting and segmenting an audience to deliver precise advertising or marketing messages. In the context of machine learning and data analytics, targeting involves using user data (behavior, demographics, interests) to create models that predict which users are most likely to respond to an offer.

Example: in an advertising campaign, targeting can be used to show ads only to users who have previously shown interest in similar products, which increases advertising effectiveness and reduces costs.

In machine learning, targeting is often implemented through user segmentation and the development of classification or recommendation models.
