# How to Run Remarketing Campaigns Using Linkrunner

Follow these steps to set up and run remarketing campaigns with Linkrunner.

<Steps>
  <Step title="Understand how reattribution works">
    Learn how Linkrunner detects returning users, the different reactivation events, and how attribution is assigned.

    [Remarketing & Reattribution](/features/remarketing)
  </Step>

  <Step title="Set up SDK prerequisites">
    Ensure your app is configured for reattribution tracking.

    * Set up [deep linking](/features/deep-linking-setup) in your app.
    * Implement the `handleDeepLink` function from the Linkrunner SDK. Refer to your SDK guide ([React Native](/sdk/react-native#handle-deeplink), [Flutter](/sdk/flutter#handle-deeplink), [Android](/sdk/android#handle-deeplink), [iOS](/sdk/ios#handle-deeplink), [Unity](/sdk/unity#handle-deeplinks)) for details.
    * Android backup configuration must be set up for reinstall detection on Android. Refer to your SDK guide ([React Native](/sdk/react-native#step-4%3A-android-backup-configuration), [Flutter](/sdk/flutter#backup-configuration), [Android](/sdk/android#step-3%3A-backup-configuration)) for details.
    * On iOS, ATT (App Tracking Transparency) permission must be granted by the user. Without ATT consent, Linkrunner cannot access the IDFA needed to identify returning users.

  <Step title="Create audience segments">
