1. Define Carterville coverage without assuming demand
Carterville is located in Williamson County, Illinois. That relationship matters when you compare the city named in your marketing with the service area your firm actually accepts. A profile limited to Carterville may not reflect a practice that handles matters elsewhere in Williamson County or in other approved areas. Conversely, a broad service area can create inquiries your office cannot serve. The Census population estimate of 5,818 is eligibility context only. It cannot tell you how many people search for a lawyer, how many firms compete for those searches or how many inquiries Local Services Ads would produce.
Recommended approach
Start with a written service-area decision: Carterville only, Carterville plus selected Williamson County locations, or a broader area your firm can serve. Separate geographic eligibility from expected performance. Review each proposed area against travel limits, court coverage, practice restrictions and consultation capacity before it is used in advertising.
