Draw the paid map in drive time, then shrink it by an hour of traffic
Radius targeting measures miles, and miles are not what determines whether you can serve a property here.
A twenty five mile circle drawn from Midtown covers Marietta, Alpharetta, Lawrenceville and Fayetteville. Those are four different dispatch problems, and at four in the afternoon on I-285 two of them are not reachable at all.
Replace the circle with a list of the specific cities and zip codes your crews already cover, grouped into zones. Ask operations to draw it, not marketing. The list will be smaller than the sales team expects and that is the point.
Then trim the edge. A property at the far boundary of a zone looks fine on a map and turns into a standing loss once the tech has to make three trips during a turnover.
Location settings also need attention. Target people who are in or regularly in your zones, not people merely showing interest, or you will pay for clicks from investors browsing from another state who will never hand you a local door.
