Start with the geography you actually serve
Kimball and St. Clair County are not interchangeable service areas. Attribution should therefore preserve the distinction between a Kimball visit, a county-level inquiry and a broader Michigan matter. The question is not how many people live in a place; check whether your records can show which geographic page or referral path preceded a qualified inquiry.
Recommended approach
Decide which geographic distinctions matter to your firm before reviewing results. Ask whether you need to separate Kimball from St. Clair County, distinguish a local landing page from a service page, or evaluate Michigan traffic at a broader level. Use those distinctions to structure review—not to assume that one location produces more cases than another.
