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.
