A twenty mile radius from a Silver Spring yard buys clicks in two states you cannot bill
Geographic targeting drawn as a circle ignores the fact that this metro is three regulatory markets stacked on one another.
Draw a twenty mile radius from most yards in this region and you have just bought traffic in the District, suburban Maryland and Northern Virginia simultaneously. If your license, insurance or permitting setup does not cover all three, you are paying for calls your office has to decline.
Start from where you can legally and practically work, then subtract where you will not send a truck. That is your map. It will look nothing like a circle.
Target by locality lists rather than radius wherever the platform allows it, and check the setting that controls whether ads show to people merely interested in a location. Interest based targeting will happily show your emergency ad to someone researching from another state.
This is the cheapest fix in the account and it is skipped constantly.
