1. Start with Marblehead’s actual service area
The attribution decision is therefore more specific: can your firm distinguish a Marblehead-origin inquiry from an inquiry connected to another place, referral source or service area?
Recommended approach
Define the geographic fields and intake questions you actually use before judging performance. Decide whether Marblehead is a service-area label, an address field, a landing-page relationship or simply one part of a broader Essex County coverage plan. Use it only to identify the place whose inquiries and outcomes you want to examine.
