1. Start with the geographic relationship you actually serve
Arlington Heights is an Illinois municipality in Cook County. The 2020–2024 ACS five-year estimate records 76,005 residents, with a margin of error of 350. That is a population record, not evidence of legal demand, competition, search volume, leads, cases or revenue. Your AI SEO evaluation should therefore begin with a service-area decision: does the firm serve Arlington Heights specifically, Cook County broadly, Illinois statewide, or a more limited geographic set? A page should not imply coverage that the firm does not provide. It should also distinguish a municipality from the county and from the state. Those distinctions matter when an AI system tries to answer where your firm practices.
Recommended approach
Create a written geographic scope for each practice area before expanding location coverage. Review whether Arlington Heights belongs on an existing service page, a location page, or both. Include Cook County only where it accurately describes the firm’s service area, and do not use the population estimate as a reason to predict results.
