1. Start with the real Highland City footprint
the Census record identifies Highland City CDP and its county relationship as Polk County. That is useful geographic context, but it is not a reason to publish every possible city-and-service combination. Highland City, Polk County, Florida and a broader metropolitan area are different scopes. Your firm should decide which of those areas it genuinely serves before selecting a footprint.
Recommended approach
Use Highland City and Polk County as a starting point for review, not as proof of demand. Confirm the communities your attorneys serve, the jurisdictions relevant to each practice area and whether a page would give a prospective client useful information rather than merely repeat a location label.
