Zelvorm Price Lab · feature
How many visitors a test needs before it starts, and a plain verdict with a p-value and the profit difference when it ends.
Before a test, the planner works out the visitors each price needs to detect the change (two-proportion test, 5% significance, 80% power) and the conversion rate the new price must reach to earn the same. During and after, you enter visitors and orders for each price and Price Lab reads it: conversion for each, the p-value, profit per visitor with a 95% interval, and a verdict (A wins, B wins, or not decided yet).
How to use it
- 1Open Price tests and start a test with the two prices.
- 2Run them on your store (alternate weeks or a split-test app) and enter visitors and orders.
- 3When there's a winner, press Use to set that price in Commerce.
