How should audience overlap be addressed in reporting?

• A. Ignore overlaps
• B. Double count overlapped users to be safe
• C. Use only one audience to avoid overlaps
• D. Exclude overlaps or use overlapping-safe reporting and pacing

Answer: (D)

Handling audience overlap in reporting focuses on preventing double-counting of the same users when they appear in multiple audience segments. When audiences overlap, metrics like reach and frequency can be inflated, which misleads interpretation, optimization, and pacing decisions.

The best practice is to exclude overlaps or use overlapping-safe reporting and pacing. Excluding overlaps means deduplicating so each user is counted once across audiences, giving a true sense of how many unique people you’re reaching. Overlapping-safe reporting and pacing use methods that account for shared audience members in the measurement and spend across segments, ensuring reports reflect actual exposure without double-counting and that budget is spent evenly across overlapping audiences.

Why the other options don’t fit: ignoring overlaps creates inflated, biased metrics; double-counting overlapped users to be safe also inflates reach and can mislead optimization; relying on only one audience eliminates valuable insights from how multiple audiences interact and limits reach.
