  • Review quality: The average rating across all connected sources, smoothed against the industry mean. So 5.0 stars from three reviews do not outrank 4.7 from three hundred.54.124%
  • Review volume: The number of reviews across all sources. The scale is logarithmic: the first reviews count the most, and the maximum is reached at 50 reviews.84.710%
  • Review recency: The age of the most recent review. Two-year-old reviews deliberately sit in the middle, because that is normal for Swiss SMEs. Only after three years without a new voice does the value drop markedly.95.08%
