1. Set the geographic boundary before you set the budget
Mount Prospect should be treated as a specific municipality within Cook County, not as a substitute for the entire county, the Chicago metropolitan area, or Illinois. Your firm may serve Mount Prospect while also accepting matters from nearby communities, but those are separate geographic decisions. Local Service Ads allow a firm to define service areas, so the useful question is not whether Mount Prospect is large enough. The useful question is which locations your attorneys can serve consistently for the practice areas you want to grow. A profile that covers too broadly may produce inquiries your team cannot handle. One that is too narrow may exclude locations the firm intentionally serves.
Recommended approach
Map each practice area against the locations your firm actually accepts. Review Mount Prospect separately from Cook County and any other service areas. Confirm whether consultation logistics, court location, travel, jurisdiction, and attorney capacity support each selected area. Do not use the Census population estimate as a proxy for advertising demand.
