1. Start with the La Grange market you actually serve
La Grange village is a municipality in Cook County, Illinois. Its ACS population estimate is an eligibility and geographic reference point, not evidence that people are searching for legal services or that any channel will produce cases. Your firm may serve La Grange, other Cook County communities, or a wider Illinois market. Those boundaries should be explicit before attribution results are interpreted. A channel that appears productive for a La Grange-focused page may not represent the same audience as a countywide service page or a page aimed at another municipality.
Recommended approach
Ask Bosseo to define the geographic labels you want attached to pages and journeys before making budget decisions. Review La Grange separately from Cook County and any broader service area. Do not combine households, individuals, municipalities, and counties into one demand assumption. Use the resulting records to identify where inquiries originate, not to predict how many inquiries should exist.
