When using the Audience Network Planner how does it describe the audience size? Estimated overall figures: the estimated monthly audience (number of people, per month, in the audience you defined).

The Audience Network Planner describes audience size as the estimated monthly audience, which is the number of unique people expected to be in the defined audience each month. This monthly metric provides a standard and actionable timeframe for advertisers to gauge potential reach and plan campaigns effectively. Weekly, daily, or yearly figures would either be too granular for strategic planning (daily/weekly) or too broad to reflect typical campaign durations and audience fluctuations (yearly). The monthly estimate offers a balanced and practical measure for campaign forecasting and budget allocation.
