Circle your shop on a map and you will pay for open water
Radius targeting is a convenience that ignores the single most important fact about this metro, which is that a straight line between two addresses often crosses a bay.
Draw twenty miles around a location in South Tampa and a meaningful share of that circle is water, with much of the rest sitting behind a crossing. The map looks reasonable. The dispatch board disagrees at four in the afternoon.
Build geography from your own service reality instead. Target by county, by city and by ZIP code, using the list of places you actually send trucks. It takes an afternoon and it is the highest return hour in the whole account.
Set location options to people in your targeted locations rather than people interested in them. The default setting will happily serve your ads to someone in Ohio researching a move, and those clicks bill the same as real ones.
Local Services Ads use their own service area settings, separate from your search campaigns. Set them from the same honest list, then check both quarterly, because service areas drift as crews change.
