Assign rails to an experiment

To assign rails to an experiment:

1. In Rails Builder, find the rail variants to be used for this experiment.

2. On one of the rail variants, click Action Segment Targeting.

3. Use the Segment Targeting Experiments tab to assign the rail to either Group A or Group B, then click Save.

4. Repeat the same procedure for the other rail variant.
   

In Rails Builder, when a rail has been assigned to one or more experiments, the Assign Segment Targeting link is replaced by an Experiments link. To view which experiments a rail is assigned to, click the Experiments link.
