How we rank

Google rating and review volume, as a Bayesian average, so a 4.9 with 500 reviews outranks a 5.0 with five.
Website popularity: estimated monthly visits, an independent signal of real-world demand.
Only businesses with at least 4.0 stars and 10 reviews qualify, and each brand appears once.
Rankings recompute automatically as our data refreshes. No business can pay to be listed or ranked higher.
