1. Define the geographic coverage before creating pages
The U.S. Census Bureau records Maryville village as a municipality in Madison County, Illinois, with a 2020–2024 ACS five-year population estimate of 8,316 and a margin of error of 23. That is useful for identifying the place and its county relationship. It does not show how many people need legal help, how many firms compete for a matter, or whether a location page will produce inquiries. Your firm should therefore decide what it actually serves before discussing page coverage: Maryville alone, Maryville and other Madison County communities, or a wider Illinois or metropolitan service area. Those are different geographic claims and should not be blended.
Recommended approach
Bring a precise service-area list to the consultation. Review whether each location reflects an actual office, an area served, or a client-intent target. Keep Maryville, Madison County, Illinois, and any metropolitan reference distinct so the site does not imply coverage the firm does not provide.
