Methodology and data limitations: The data was collected from TikTok Ads Manager and reflects the minimum potential audience estimate for the selected targeting. The figures do not account for overlap with other targeting dimensions such as device, behavior, or interests. These estimates are useful for forecasting technical reach, but they require additional validation of unique users after accounting for audience overlap.
