Flags campaigns spending a large share on people outside the area you're targeting - common for local-service clients when location settings are too loose (e.g. "presence or interest" instead of "presence"). The fix is usually tightening location targeting or adding exclusions.
Defaults & settings
Out-of-area spend threshold - the share of spend going to people outside the targeted locations that triggers it. Default 30%, adjustable 5-75%.
Checks weekly; 7-day cooldown per campaign.
Example. A pool installer serving one metro area is quietly spending 38% of budget on clicks from three states away, via "interest in" matching. One weekly flag, one settings change, double-digit waste gone.
