Media planning involves determining the optimal platforms and messages to reach the target audience. It requires understanding consumer behavior and media consumption habits to select the appropriate media channels and schedule for advertising campaigns. The goals are to maximize reach and frequency among the target market while minimizing costs. Media planners consider objectives like reach, frequency, continuity and budget. They analyze past performance and research to create a media strategy and plan that is implemented through media buying. Evaluation of results helps assess the plan's effectiveness and identify lessons for future campaigns.
