What review volume does to the damage

The same bad review on a bigger pile barely moves the needle.

25 reviews-0.14
50 reviews-0.07
100 reviews-0.04
250 reviews-0.01
500 reviews-0.01

The real defense against bad reviews is volume. At 300 reviews a one-star is a rounding error. At 20 it is a crisis. Go get reviews before you need them.

The lead impact here is a rough model, not a measured fact. Ratings are one of many things people weigh. The direction is reliable, the exact dollar is not.

What this assumed

  • The link between rating and enquiry volume is modelled from your own numbers, not from an industry study.

Runs in your browser. Nothing you type is sent anywhere.

This is an estimate

This tool returns an estimate based on the numbers you entered. Your real result depends on your own costs, rates and conditions. Check it against your own records before you make a decision with it.

What this tool actually does for you

Who it is for

Anybody who just got their first bad review and feels sick about it.

The problem it points at

A bad review feels personal. What matters is what it does to the number people sort by.

What you walk away with

Perspective, plus the exact number of good reviews that erase it.

How to use it

  1. Enter your rating and review count.
  2. See what one, three or five bad reviews do.
