1. Start with the geography your firm actually serves
Bosseo describes Programmatic SEO as dedicated pages for each legal service in each city within a chosen footprint. Its public page says a firm can choose statewide coverage or limit the work to selected counties. For Warrenton, the named municipality is Warrenton city and the recorded county relationship is Warren County. Those are not interchangeable targets: a page about Warrenton city, a page addressing Warren County, and a page for another Missouri city each require a distinct service and geographic rationale. The Census population estimate can confirm that Warrenton is a real municipality to consider, but it cannot tell you whether people search for a particular lawyer there or whether a page will produce a case.
Recommended approach
Bring Bosseo a precise service map: Warrenton city, Warren County, other Missouri counties, or a broader state footprint. Exclude places the firm does not serve. Ask how each proposed page will contain useful local and state-specific information rather than merely changing the place name.
