How the Ajax standings are built
Rank = Google rating × review volume. We read the public Google listing for every
business serving Ajax, in October 2026, and order each 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, so a business that gains reviews this month moves next month.
