1. Start with the service area, not the review count
The U.S. Census Bureau records Summerville as a municipality with an estimated 51,654 residents in the 2020–2024 ACS five-year data, with a margin of error of 63. The same record places the town in Berkeley County, Charleston County and Dorchester County. For reputation work, the useful local question is narrower: which people and matters does your firm actually want to attract? A firm serving Summerville and nearby parts of all three counties may need a different review-request and response policy from a firm serving one county or a statewide practice.
Recommended approach
Write down the intended geographic scope before evaluating performance. Review whether your Google Business Profile, website, consultation language and review responses describe the same service area.
