1. Start with the geography your firm can serve
Thetford township is in Genesee County, Michigan. Bosseo’s public product description says a firm can choose statewide coverage or limit the footprint to selected counties. That makes the county boundary a practical decision point: do not treat a Thetford page as permission to claim service throughout Michigan, or even throughout Genesee County, unless your firm genuinely serves those places. The Census population estimate identifies the municipality; it does not establish that residents are looking for a lawyer, that a particular legal service is needed, or that nearby firms are competing for the same search.
Recommended approach
Decide whether Thetford belongs in a county-level footprint based on your intake territory, court and filing knowledge, licensure, conflicts policy, and willingness to respond to inquiries from that area. If your reach is narrower than Genesee County, use a narrower service-area statement rather than implying countywide availability.
