1. Start with the geographic record, not a demand assumption
Marple is recorded as a municipal-town in Pennsylvania, and its county relationship is Delaware County. The ACS 2020–2024 five-year estimate is 24,216, with a margin of error of 34. That is a description of the place and population, not proof that residents are searching for a particular practice area or that one marketing channel is producing cases. Attribution should therefore be evaluated against the geographic distinctions your firm actually uses: Marple township, other Delaware County communities, Pennsylvania-wide service areas, and any metropolitan descriptions appearing in your marketing. A source record that says only “Google” cannot answer whether a prospective client reached you through a Marple-focused page, a service page, an advertisement, a referral or a later return visit.
Recommended approach
Ask to see whether the proposed attribution view preserves the landing page, referrer and channel for each inquiry. Decide in advance which geographic distinctions matter to your practice and avoid treating the population estimate as a forecast.
