Reviews can influence trust, but a website visit becomes a sale through many factors: lead quality, price, availability, sales response, competition, location, seasonality, and customer experience.

This calculator therefore asks you to supply the conversion-rate change. It does not claim that a particular number of reviews will produce that change.

The scenario calculation

  1. Multiply monthly qualified leads by the conversion-rate increase you entered.
  2. Multiply the modeled additional customers by average customer lifetime value.
  3. Multiply the monthly value by 12 for an annual scenario.

Use conservative assumptions

Start with a small conversion change, use qualified leads rather than total website traffic, and use a customer lifetime value based on actual business records. Compare the scenario with real results over time.
