How Provenly works

ProvenScore

A 0.0–5.0 score that blends Provenly reviews with the business's Google rating. Provenly reviews count the most.

1. 1. Each Provenly review is weighted by how well it was verified and how recent it is. Its weight halves every 18 months.
2. 2. Google's rating counts a little. Each Google review counts as 0.25 of a Provenly review, and at most 50 Google reviews are counted.
3. 3. A small starting point of 3.8 worth 3 reviews stops one review from swinging the score.

score = (Σ wᵢ·ratingᵢ + g·googleRating + 3·3.8)
        / (Σ wᵢ + g + 3)
wᵢ = tierWeight × 0.5^(ageMonths / 18)
g  = min(googleCount, 50) × 0.25
