Start with the geographic boundary that matters
Red Hill is recorded as a CDP in Horry County, not as a separate county or metropolitan area. That distinction matters when you review attribution. A report that combines Red Hill, other Horry County communities and broader South Carolina traffic may be useful for a larger market view, but it should not be mistaken for Red Hill-specific evidence.
Recommended approach
Ask for geographic reporting that keeps Red Hill identifiable and distinguishes it from Horry County and any broader service area. Decide whether the firm needs to evaluate only Red Hill journeys or compare them with other places it serves. Use actual inquiry and matter records to determine whether a geographic segment deserves further attention.
