About Variant Target Allocation
The target allocation setting dictates how the system should allocate traffic to an individual variant. In a Continuous Optimization project, the default allocation is 'auto', allowing the system to determine how often visitors should see a variant based on its performance.
This setting allows you to scale up or down the percentage of visitors that will see an idea.
The allocation value is a "target"
The actual percentage will differ until the system has a chance to create or remove combinations. You can see the actual vs. target percentage in the Performance of Variants report.
The allocation only works in the Optimization phase
The Optimization phase is where the system actively removes and generates combinations, allowing it to match the target allocation.
Setting the target allocation for a variant
The ability to set a variant's target allocation is automatically available to all Evolv AI accounts.
- Open the Evolv AI Manager and select a project.
- Make sure you're on the LIVE tab.
- Navigate to the Variants pages from the side navigation.
- Scroll down to find the Organization of Variables listing.
- Click on the variable of the variant you want to edit.
- Click the options menu (the three dots) next to a variant and select the Allocation option.
- Set the allocation target and click the tick icon to save.
- To remove the allocation, click the options menu and select Remove Allocation.
The percentages allowed are based on the number of combinations that can be active at one time. This is because a variant will only be shown to visitors when included in a combination.
The maximum allocation of a non-control variant is limited to the total number of active combinations minus 1 for control. For example, a project with 10 active combinations can allocate a non-control variant to 9 combinations, or 90% of the traffic.
Identifying variants with target allocations
Target allocations appear in the Performance of Variants list after reloading the page. This provides the allocation information at a glance.
