+
+> info ""
+> The randomized splits step is in beta and available to users with a Personas Advanced plan.
+
+A randomized split lets you experiment with and test the performance of a Journey's branches. When you create a randomized split, you add up to five Journey branches, each with a different step. Journeys then sends eligible users down one of the branches at random. Each branch receives a portion of the eligible users based on percentages that you assign to the branches.
+
+To test your messaging channels, for example, you might create a randomized split with three different branches, assigning 40% of users to an email campaign, 40% to an SMS campaign, and 20% to a control group. Once users flow through the split, you can determine the success of the email and SMS campaigns compared to each other and the control group.
+
+### Add a randomized split
+
+Follow these steps to add a randomized split to a Journey:
+
+1. Create a new Journey, and [add an entry condition](#adding-the-entry-condition).
+2. Select the **+** icon to add a step, then select **Create a randomized split**.
+3. Name the randomized split step, then add up to five branches.
+4. Set the distribution percentage for each branch, then select **Save**.
+5. For each branch in the split, select the child **+** icon and add a step.
+3. Save and publish your Journey.
+
+Users who meet the Journey's entry condition will then enter the Journey and flow through the randomized split.
+
+### Act on the split's results
+
+Once users complete your Journey's randomized split step, you'll have insight into how each split performed. You can take action on the results by cloning the Journey and sending a new set of users through the highest performing branch.
