A/B Test Your Popups. Stop Guessing.
Hello Bar A/B testing lets you create two versions of any popup, split your traffic, and let the results decide. Hello Bar shifts impressions toward the winning variant automatically as data comes in.
How A/B testing works in Hello Bar
Build your variants
Create two or more versions of any popup. Test the headline, the offer, the design, the timing, or the trigger type.
Go live
Hello Bar splits your traffic and runs both versions at the same time on your site.
Read the results
Hello Bar tracks views, clicks, and conversions for every variant, then shifts your traffic toward the winner while the test is still running — so you stop paying for the losing version.
Every element. Every format.
If a visitor can see it, you can test it — and the split keeps adjusting while the test runs.
- Unlimited tests on Growth, Premium, and Elite
- Any element of a popup: headline, copy, CTA button, design, timing, trigger type
- Automatic traffic shifting: the split adjusts while the test is still running, so more of your visitors see the winner before you have declared one
- Results dashboard: conversion rate per variant, with date range and traffic split shown
- Works with every popup format: modals, bars, sliders, alerts, page takeovers, and gamification popups
