Frequency across overlapping targets

Advertising semantics

When two or more targeted geographies overlap (e.g. a store radius nested inside a DMA target), a user in the overlap can receive frequency from both line items, inflating true frequency and reach reporting per user.

Detection

Compute geographic overlap between concurrently active targets; nonzero overlap area with independent frequency caps per line item.

Mitigation

Apply a global (cross-line-item) frequency cap, not a per-line-item cap, wherever targets can overlap
Report deduplicated reach/frequency across the overlapping set, not summed
