With A/B Winner Autoselection, you can authorize the AI-backed system to select the winner path and direct all users to that path automatically based on the metrics you select. This feature removes the need to manually check the A/B split results, track each path's success, and create another journey with the winner path. Instead, you can enable the autoselection, let the system determine the best path in a specific duration, and automatically direct users to that path once the calculation is completed.
A winner path enables you to send your messages to the right users at the right time with the right content by the right channel and engage your users. This will help you:
- Improve the performance of your journey,
- Take actions based on A/B test results,
- Increase the effectiveness of the journey by allocating users to the option with better conversions.
How does the A/B Auto-Winner Selection work?
Once you enable Winner Autoselection on the A/B Split element, the system calculates the best path according to two variables: winner metric and calculation duration. For example, you select Conversions as your winner metric and set your calculation duration to 30 days. You launch your journey and wait for 30 days for the announcement of the winner path. The Winner Autoselection determines the best path that brings the most conversions within this duration.
To enable winner autoselection, follow these steps:
1. After adding the A/B split element, check the Enable Winner Autoselection box.
2. Select one of the following metrics for the system to use to determine a winner:
- Total opens & clicks: Total opens and clicks of the channel used in the A/B split path(s).
- Open & click rate: Open and click rate of the channel used in the A/B split path(s).
- Conversions: Conversions of the channel used in the A/B split path(s).
- Conversion rate: Conversion rate of the channel used in the A/B split path(s).
- Revenue: Revenue of the channel used in the A/B split path(s).
3. Select an autoselection limit: Time limit or user limit. The system uses this limit to finish the calculation of the winner.
If you enable the "Extended Path Allocation," it will allow you to distribute a small percentage of users equally across the remaining non-winner paths after the "Winner Autoselection" is completed. If one of these non-winner paths becomes the new winner, the winner will update accordingly. Once the Architect identifies the new winner, the users allocated under "Extended Path Allocation" will continue to follow the remaining paths, and this cycle will repeat. 
Once you enable Extended Path Allocation, Architect allocates the users equally based on the percentage you selected.
