How these standings are built

Rank = Google rating × review volume. We read the public Google listing for every business on these boards, in October 2026, and order each town board by that score. There are no submissions and no fees. A business moves up by earning reviews. Featured placement is available to claimed businesses, is always labelled as such, and never changes a rank. The boards are refreshed monthly.
