Start with the Fort Dodge service area, not a population assumption
Your first decision is geographic. Fort Dodge is recorded as a municipality in Webster County, so a Local Service Ads review should distinguish the city from the county and from any surrounding area your firm is authorized and prepared to serve. The population estimate is useful context for defining the place under review, but it cannot tell you how many people search for a lawyer, how many firms compete for a category or how many calls an account may receive. Bosseo’s public Local Service Ads page says its service includes category and geography targeting. That makes the service-area question an implementation choice rather than a demographic conclusion.
Recommended approach
Bring a written service-area policy to the consultation: locations you serve, locations you do not serve, matters you accept and matters you refer elsewhere. Ask how those boundaries would be reflected in the profile and how an out-of-area inquiry would be identified and handled.
