-
Open your offer from the Offers page.
-
In the A/B test section, click Start an A/B test.
-
Edit the Version B tiers. They start as your tiers with 5% more off.
-
Use Preview version to check how version A and B look.

Click Save to start the test.

Come back to the offer to see Views, Add-to-cart rate, Orders and Revenue for each version.

A/B test results per version, the end-test buttons and version B's tiers -
Click Keep A and end test or Use B and end test to finish.
- Note: Visitors are split 50/50. Each visitor always sees the same version, and the checkout discount matches it.
- Note: Results become reliable after about 100 views of each version. A banner tells you when one version is winning.
- Note: If you change the tiers of either version, the results start again from that save.
- Note: Before you save, click Cancel test to drop version B.
- Note: Version B must differ from version A in at least one discount or label.
