A/B testing
Last updated Jul 22, 2026
A/B testing lets you settle offer decisions with evidence instead of opinion.
What you can test
Test product, discount, or headline variants of an offer, on any placement.
How it works
- Create two or more variants of an offer.
- UpsellEngine splits traffic between them automatically and tracks acceptance and revenue for each.
- When a variant reaches 95% statistical confidence, UpsellEngine declares the winner automatically and reports it in plain English — no statistics background required.

Reading results
Results appear alongside your other metrics in Analytics. Because the winner is only called at 95% confidence, you avoid acting on early noise — a variant often looks ahead simply because few shoppers have seen it yet.
See the A/B testing feature overview for more. A/B testing is available on the Growth plan and above (Plans & billing).
