How These Rankings Work

Scores come from Google Reviews via the Google Places API — never from paid placements, and never set by the agencies themselves. We apply a Bayesian adjusted average to prevent small-sample distortion (a 2-review 5.0-star agency shouldn't outrank a 200-review 4.8-star one):

adjusted_score = (v / (v + m)) * R + (m / (v + m)) * C
  • v— total reviews across all offices
  • m— prior weight (20)
  • R— the agency's weighted average score
  • C— the platform-wide mean

So with a global mean of 4.2: an agency with 5 reviews at 5.0 scores 4.36, while one with 200 reviews at 4.8 scores 4.75. The second outranks the first because the score is backed by more evidence.

Multi-office agencies get a single weighted score across locations. Every listing is human-reviewed before publication. Scores refresh hourly. Read the full methodology →
