1. Start with Portland’s actual service boundary
Portland is a municipality in Cumberland County, Maine. The 2020–2024 ACS five-year population estimate for Portland city is 68,854, with a margin of error of 52. That is geographic and population context—not proof of legal demand, search volume, competition, calls or revenue. Your attribution design should therefore distinguish Portland matters from inquiries elsewhere in Cumberland County and from matters your firm serves across Maine. A city name in a landing page or intake record is not, by itself, a reliable source of business.
Recommended approach
Agree on the geographic fields that matter before reviewing performance: the client’s service location, the office or team responsible, and the marketing geography that generated the inquiry. Review whether those fields are captured consistently and whether a Portland inquiry should be evaluated differently from a Cumberland County inquiry outside the city.
