A twenty-mile radius from your office buys half a bay you cannot serve
Radius targeting treats water as ground, and the crossings between Hillsborough and Pinellas do not behave like map distance.
Draw twenty miles around a downtown Tampa office and you have bought Clearwater, Largo and a good share of Pinellas. On the map it looks like one market. At four in the afternoon it is not.
The result is not a wasted click so much as a wasted consultation. Someone in Pinellas Park books an in-person slot, discovers what the trip costs, and cancels or does not appear. You paid the click, the intake time and the empty hour.
Replace the circle with named targets. Hillsborough and Pinellas as separate geographic groups, with Pasco separated too if you take work from Wesley Chapel and Lutz. Separate groups mean separate bids, separate ad copy and separate reporting.
Radius targeting is a default, not a decision. In this metro it is usually the wrong default.
