1. Start with the geography your firm actually serves
A River Grove practice may handle matters for people in River Grove, elsewhere in Cook County, or beyond Illinois. Those are different geographic relationships, and attribution should not collapse them into one “local” label. Bosseo’s public Lead Attribution page says its records can include the landing page, referrer, channel, device, sessions, intake answers, calls, consultations, and signed cases. The useful review question is therefore not whether River Grove’s population is large enough to support a conclusion. It is whether your records can distinguish a River Grove inquiry from a Cook County inquiry and from a matter outside the area you intend to market.
Recommended approach
Define the geographic fields and reporting views you want to inspect during a consultation. Use River Grove as a precise municipality, Cook County as the recorded county relationship, and Illinois as the state scope. Treat each as a reporting choice rather than evidence of demand.
