Weight
  • 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.70.824%
  • 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.27.910%
  • 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.88.08%
Herbert Waser Hewatec scores 67.8 out of 100 points in the Substance area of the ranQ Trust Score. This area carries 28% of the weighting.

CriterionValueWeight
  • Establishment: Years since founding or brand launch, logarithmic. The maximum is reached at 15 years.75.012%
  • Company size: The headcount band, researched by ranQ or stated by the company. It is scored in steps rather than by head count, because the data only provides bands.55.07%
  • Legal form: Graded by liability and disclosure. The weight is kept small: a sole proprietorship is not a dubious company, it is just liable differently.67.06%
  • Branch offices: Branch offices linked in the commercial register. Having none is normal and costs no points.70.03%
Herbert Waser Hewatec scores 85.0 out of 100 points in the Identity area of the ranQ Trust Score. This area carries 22% of the weighting.

  • Website authority: Ahrefs' Domain Rating measures, on a scale of 0 to 100, how strongly a website is linked from other websites. For Swiss SMEs the range up to 40 is typical; the maximum is reached at 35.0.94%
  • Media authority: No data point — the criterion is taken out of the weighting and does not lower the score.—4%
