Objective

Daily Unique Reach (DAU) is a metric used to measure the number of distinct individuals who encounter a specific piece of content, advertisement, or platform within a single 24-hour period. Unlike total impressions, which can count multiple views by the same person, Daily Unique Reach focuses on unique users, providing a clearer sense of the true audience size on a given day. This measurement is particularly important in digital marketing, social media analytics, and advertising, where understanding audience exposure without duplication helps inform strategy, optimize campaigns, and allocate resources efficiently. Daily Unique Reach often complements other metrics such as engagement rate and total reach to provide a comprehensive view of audience interaction and campaign effectiveness.
