1. Start with the geography you actually serve
Your location decision should distinguish Marion from Linn County and from any broader service area. The Census record identifies Marion as a municipality in Linn County, Iowa. It does not show where potential clients search, which communities your firm accepts, or whether a broader radius would produce useful inquiries. Local Service Ads allow service-area decisions to matter because the program is built around local visibility and lead generation. The relevant question is not whether Marion is large enough. It is whether your selected geography matches the matters your firm can accept and the places your attorneys actually serve.
Recommended approach
Write down the cities, county areas and travel boundaries you are prepared to serve. Then compare that policy with the geographic settings available for the campaign. Keep Marion and Linn County distinct in your planning, and do not describe the entire county as your market unless your firm has made that decision.
