Separate Auburn geography from attribution evidence
Auburn’s recorded county relationships include King County and Pierce County. A firm may therefore need to distinguish Auburn matters from contacts associated with either county, nearby communities or a broader Washington service area. Population alone cannot establish which geography produces inquiries or signed cases. Attribution should preserve the location information your firm actually collects and let you compare it with the originating page, channel and case-type information. The decision is not whether Auburn is large enough to justify a claim. It is whether your records can show which geographic and service paths lead to qualified inquiries.
Recommended approach
Before changing budget or coverage, define the geographic labels your firm uses for Auburn, King County, Pierce County and any other service areas. Review whether those labels are captured consistently in intake and whether they can be compared with source and outcome records.
