Frequently Asked Questions
How accurate is the ROI calculator?
The calculator uses a conservative 1.5x conversion lift estimate. The Spiegel Research Center found that displaying reviews can increase conversion rates by up to 270%. We deliberately use a conservative figure to keep projections realistic — your actual results may be higher or lower.
What data do I need to use the calculator?
Just three numbers: monthly website visitors, current conversion rate, and average order/deal value. Use the sliders to adjust and see results in real time.
Why a 1.5x conversion lift?
The Spiegel Research Center's research is one of the most cited studies on review impact. They found increases of up to 270% (3.7x), but results vary widely by industry and implementation. We use 1.5x as a conservative, credible starting point.
