How this ranking works
- Rankings are computed from published Google ratings and review counts for active companies in our directory, refreshed with our data pipeline.
- Every company needs at least 10 Google reviews to be ranked. Scores use a weighted (Bayesian) average so a small number of perfect reviews does not outrank a large body of near-perfect ones.
- A city is only ranked when at least 5 companies meet the review minimum.
- Placement cannot be purchased. No company paid to appear, and claiming a listing does not affect rank.
