1. Start with the geography your firm actually serves
Bosseo describes Programmatic SEO as coverage that can be scoped statewide or to selected counties. York township is a municipal-town in York County; those are not interchangeable geographic labels. A page targeting York township should not silently represent every place in York County, and a county-wide plan should identify the cities included rather than treating the county as one undifferentiated location. The Census population estimate for York township can help establish that the place is a real geographic area, but it cannot establish demand or justify a particular page count.
Recommended approach
Bring Bosseo a written service-area map. Decide whether your intended footprint is York township, other York County municipalities, York County as a county-level service area, or a broader Pennsylvania footprint. Ask which location labels will appear in page titles, copy, internal links and measurement. Keep any expansion decision tied to actual service capacity and reviewable inquiry data, not population alone.
