# Run A/B Tests and Targeting Rules

Use rules to test destinations and target users by context (geo/device/browser/referrer/time).

<Steps>
  <Step title="Define test hypothesis and success metric">
    Choose one metric first: click-through quality, lead rate, or sale value.
  </Step>

  <Step title="Create target destinations and fallback">
    Prepare all destinations before enabling rules.
  </Step>

  <Step title="Configure rules and priority order">
    Set the most specific rules first, broader rules later, fallback last.
  </Step>

  <Step title="Send controlled test traffic">
    Validate which rule matched in analytics and events.
  </Step>

  <Step title="Promote winner and archive obsolete rules">
    Reduce complexity after test concludes.
  </Step>
</Steps>

## Guardrails

* Keep one clear fallback.
* Avoid overlapping high-priority rules with ambiguous conditions.
* Document rule changes and effective dates.
