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

  1. Create two or more variants of an offer.
  2. UpsellEngine splits traffic between them automatically and tracks acceptance and revenue for each.
  3. 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).
