1. Set the service area around the matters you actually accept
Google Local Services Ads use categories and service areas, so geographic scope is an operating decision rather than a reason to assume demand. Great Falls is a CDP in Fairfax County; the available population record describes that place and county relationship, not every community your firm may serve. A firm can therefore begin with a precise question: should the profile cover Great Falls alone, Fairfax County more broadly, or additional areas that the firm intentionally serves? The answer should follow licensure, office capacity, court or client logistics, and accepted case types—not the population estimate by itself.
Recommended approach
Map each practice area to the locations your firm is prepared to serve. Review whether Great Falls should be a distinct service-area choice or part of a wider Fairfax County plan. Keep location coverage and practice-area coverage separate so an inquiry is not treated as qualified merely because it came from the right place.
