Every theme change, backed by real data
Split your Shopify store's traffic between your live theme and a challenger, and measure what the redesign changes: conversion rate, AOV, and profit per theme. A decision, not a gamble.


Pick a theme to challenge your live design
Choose any theme from your Shopify library: a full redesign, a seasonal version, or a template you're evaluating. Your live theme stays untouched while the challenger competes for its place.

Split traffic between themes automatically
Personizely divides visitors between your themes in real time. Each visitor sees one design consistently for their whole visit, so the comparison stays clean and the shopping experience stays normal.

Test on all traffic or just a slice
Run the test on your whole store or a specific audience: one market, mobile shoppers, new visitors. Target by location, device, traffic source, and 20+ other conditions.

The numbers make the call, you make the switch
Track conversion rate, revenue per visitor, AOV, and goal hits for every theme. Break results down by goal: purchase, add to cart, checkout start. When a winner emerges, make the switch knowing exactly what it earns you.
