1. Set the geographic boundary before changing pages
Those are different geographic claims. Your site should therefore distinguish St. Louis from any additional places your firm actually serves. A page that blurs city, county and metropolitan coverage can make it harder for both people and search systems to understand where your services apply.
Recommended approach
Begin with a service-area review. List the locations your firm intentionally serves, identify which practice areas apply in each location, and remove wording that implies broader coverage than the firm can support. Treat the 288,512 population estimate as context for the municipality only, not as a reason to predict demand or expand coverage.
