1. Start with the service area you can responsibly serve
Bosseo says its programmatic SEO product can be scoped to an entire state or to counties selected by the firm. Chester’s recorded county relationship is Rockingham County, so the first practical question is whether your firm serves Chester alone, communities throughout Rockingham County, or a broader New Hampshire area. The Census estimate for Chester does not establish that residents are searching for a particular legal service, nor does it show that a county-wide page set would be commercially appropriate.
Recommended approach
List the towns and counties your firm actually accepts matters from. Then separate locations where you have meaningful service relevance from locations that would merely add page count. A Rockingham County footprint may be worth reviewing if it matches your intake policy and substantive service area; do not select it solely because Chester has a recorded population.
