1. Define Henderson as a real service area, not a population proxy
The Census record identifies Henderson as a municipality in Rusk County, Texas. That relationship matters when you decide whether a county-limited footprint is appropriate. It does not justify claims about how many people search for a lawyer, how many firms compete, or how many matters a page could generate. Bosseo’s public Programmatic SEO page says its engine can be scoped to the whole state or to counties chosen by the firm. For your consultation, distinguish Henderson city pages from pages for other cities in Rusk County and from pages elsewhere in Texas. Those are different geographic decisions with different review requirements.
Recommended approach
Give Bosseo a written service-area definition: Henderson city, Rusk County, additional counties, statewide Texas, or a combination that the firm can actually serve. Ask for a proposed city-and-service map before approving coverage. Do not expand the footprint merely because the city’s population is known.
