1. Start with the geography you actually serve
Eugene is a municipality in Lane County, Oregon. The 2020–2024 ACS five-year estimate records 179,591 residents, with a margin of error of 78. That is context for defining a service area; it does not establish legal demand, search activity, competition, lead volume or revenue. Your attribution design should therefore distinguish Eugene from other Lane County locations and from any broader Oregon market your firm accepts. A source record should answer where the person entered your journey and what matter they described—not presume that a Eugene visit represents the whole county or that a county inquiry belongs to an Eugene office.
Recommended approach
Before reviewing performance, write down the geographic distinctions that matter to intake: Eugene, Lane County outside Eugene, and any other areas your firm serves. Decide whether location is collected as an intake answer, reviewed by staff, or handled through another existing intake field. Use those distinctions for analysis only where the information is actually available.
