1. Set the geographic boundary before choosing page coverage
Marysville is a city in St. Clair County, Michigan. Bosseo says its programmatic SEO offering can be scoped to a whole state or to selected counties. That makes the county relationship more useful than the city name alone: you can ask whether your firm serves only Marysville, the wider county, or a broader Michigan footprint. The Census population estimate of 9,925 describes the municipality, not the county, metropolitan area, households, or legal-service demand. It should not be used to justify a page count or a forecast.
Recommended approach
Bring a precise service map to the consultation. Separate cities where the firm has a meaningful service relationship from places included only because they appear on a map. Ask Bosseo to explain how the chosen footprint would translate into pages for each practice area and whether a narrower St. Clair County scope is more appropriate than statewide coverage.
