How is Best of Marengo 2026 chosen?

Purely from Google data. A business qualifies with a Google rating of 4.5 or higher and at least 5 Google reviews; within each trade the top three are ordered by rating, then review count. No business can pay to appear here, and the list is recomputed daily from each business's Google Business Profile.
