# How to Run an A/B Test

> Start an A/B test to compare two variants of a version and roll out the winner.

An A/B test splits traffic between two variants of a version so you can find what performs best, then rolls out the winner. This is the short version; for the detail, start with [how A/B tests work](/knowledge-v2/referral/campaigns/ab-testing/how-ab-tests-work).

<Steps>
  <Step title="Start the Test">
    To test against your live version, click **Set up A/B test** on it (or the recommendation in the insights panel), name the new version and click **Create test**. To test two fresh ideas on a draft, click **+ A/B test** on the section you want to test.
  </Step>

  <Step title="Choose How It Runs">
    In the wizard, pick the **test metric** (conversion rate or share rate) and the **test speed**, then set what happens **when it concludes**. See [set up an A/B test](/knowledge-v2/referral/campaigns/ab-testing/set-up-an-ab-test).
  </Step>

  <Step title="Differentiate the Variants">
    Edit **Variant B** so it differs from the control in one way. See [manage an A/B test](/knowledge-v2/referral/campaigns/ab-testing/manage-an-ab-test).
  </Step>

  <Step title="Launch and Monitor">
    Launch the version like any other, then follow the result on [monitor an A/B test](/knowledge-v2/referral/campaigns/ab-testing/monitor-an-ab-test).
  </Step>
</Steps>
