Audience targeting is a methodological approach and academic concept focused on the identification, segmentation, and selection of specific subgroups within a larger population for tailored communication or intervention strategies. It investigates the demographic, psychographic, behavioral, and attitudinal characteristics of these groups to understand their susceptibility and responsiveness to particular messages or actions. Its significance lies in optimizing communication effectiveness, resource allocation, and impact analysis across diverse fields such as marketing, public policy, education, and media studies.
