Start with the geography your firm actually serves
O'Fallon is recorded as a municipality in St. Charles County, Missouri. The 2020–2024 ACS five-year estimate records 93,801 residents, with a margin of error of 84. That is location context, not proof of search demand, legal need, leads or revenue. It does, however, give your firm a clear boundary for an initial hosting and website review: examine the site that serves O'Fallon and the wider areas your practice intentionally covers, rather than treating every Missouri visitor as the same audience. Hosting should support the actual site structure, intake paths and geographic scope you decide to publish.
Recommended approach
Bring a current site map and identify which pages matter to O'Fallon visitors. Ask whether the present host can support those pages reliably, whether the domain and DNS remain under your control, and how a future migration would preserve the pages and records your firm has approved.
