1. Set the geographic boundary before setting a budget
Your first decision is what “Chatham” means for the campaign. The Census identifies Chatham as a municipal town in Barnstable County, Massachusetts. That is a precise geographic relationship, but it is not evidence that every resident is a potential client or that the town alone will support a particular advertising budget. Bosseo’s public Local Services Ads page describes category and geography targeting, including service areas set according to the case types and locations a firm wants. That makes geographic scope a firm decision rather than a conclusion drawn from population.
Recommended approach
Review the addresses and communities your firm is actually prepared to serve. Decide whether Chatham should be treated as a standalone service area or considered alongside other areas your firm intentionally accepts. Keep the town, county and any wider coverage area distinct in your internal reporting so an inquiry from outside Chatham is not mislabeled as a Chatham result.
