Start with the service area you actually accept
Bosseo’s public Programmatic SEO page describes coverage by state or by selected counties. For a firm serving Washingtonville, that makes Orange County the relevant starting relationship—not an excuse to treat every nearby place as interchangeable. Washingtonville is recorded as a municipality in Orange County, New York. Your intake rules may extend beyond the village, stop at the county line, or vary by practice area. Those distinctions should determine the geographic footprint.
Recommended approach
Bring a current service-area list to the consultation. Separate Washingtonville from the rest of Orange County and identify any other New York counties you intentionally serve. Decide whether each practice area uses the same footprint. Do not expand solely because a place appears on a map or because its population is known.
