1. Start with the service area you can actually serve
Bosseo’s public Programmatic SEO page says a firm can choose statewide coverage or limit the footprint to selected counties. For a Murphysboro firm, the recorded relationship is specific: Murphysboro city is in Jackson County, Illinois. That makes a county-level review more precise than treating every nearby place as interchangeable. The city’s ACS population estimate is useful as geographic context, but it cannot tell you whether residents search for a particular legal service or whether a page will produce a qualified inquiry.
Recommended approach
List the Illinois cities and counties your firm is prepared to serve, then compare that list with the footprint under consideration. Ask Bosseo to evaluate whether Murphysboro-only coverage, Jackson County coverage or a broader Illinois scope would create useful pages without claiming service in places your firm does not serve.
