After you finish a checkout UI test in ABConvert, you will usually want to roll out the winning version to all visitors. This guide shows two practical ways to apply the winner.
When to use this
You have a clear winning checkout UI test group
You want all visitors to see the winning checkout design
Option 1: Set winner traffic to 100%
This is the fastest way to apply the winning group inside ABConvert.
Go to your ABConvert tests
Find your checkout ui test, in the Actions dropdown, click Edit
In Traffic Percentage settings, set the winning group to 100%.
All eligible visitors will now see the winning checkout UI while the test remains active.
Option 2: Implement UI in Shopify's Checkout Blocks app
If you want the winning UI to stay live without relying on an active test, rebuild it in Shopify’s checkout customization app: Checkout Blocks.
⚠️ You may not be able to recreate the winning UI exactly in Checkout Blocks, depending on the elements used in the test.
Because of this limitation, we are planning to release a feature that lets you permanently keep an ABConvert checkout block after a test ends.
