One account cannot serve a Dallas docket and a Fort Worth docket
Dallas and Fort Worth are separate markets with separate downtowns and an hour of freeway between them, and one campaign averaging both tells you nothing useful.
A radius drawn around your office looks tidy on a map and spends badly. Thirty miles from a Dallas address reaches into Tarrant County, where a different set of firms has been buying the same clicks for years and where your attorneys may not want to appear anyway.
Set geography to the counties you file in, as separate campaigns with separate budgets. Dallas County in one. Collin and Denton together or apart, depending on volume. Tarrant only if a partner drives there, and never because the map looked incomplete.
Check the targeting method as well as the shape. Platforms will show your ads to people merely interested in a location unless you restrict to people actually present there. A family law account with that setting wrong pays for browsing from other states, and the resulting inquiries are unworkable.
Separation also gives you the ability to turn one county off. When Denton is producing inquiries nobody follows up on, you want to be able to pause Denton without touching the campaign that is working.
