OneLink™ deep linking guide


Deep linking is the act of launching a mobile app while serving personalized content and/or sending the users to specific activities within the app. By doing so you provide users with superior user experience, greatly enhancing their engagement with the apps.

Brand your one links using Branded Links

Two types of deep linking

Since users may or may not have the mobile app installed, there are two types of deep linking:

Deep Linking
Directly serves personalized content to existing users, which already have the mobile app installed.
Deferred Deep Linking
Serving personalized content to new or former users, directly after the installation.

AppsFlyer supports both deep linking and deferred deep linking methods using its unique device detecting attribution link - OneLink™.

This guide covers all you need to know about the setup and usage of deep linking for your mobile apps. We recommend that a marketer and developer review this guide together, because this guide covers setting up deep links both in AppsFlyer dashboard and in the app.


Deep linking relies on the correct setup of OneLink.

Deep linking and OneLink

OneLink operates as a "bridge" between the advertisement and the mobile app. It can launch the app and provide the mobile developer with the data required to personalize the user experience. To do so develop the mobile app with deep linking capabilities and infrastructure.

Deep linking and retargeting

Deep linking and OneLink are used to re-engage existing or past users, meaning to retarget them. This subject is covered in the retargeting guide, which should be reviewed after this deep linking guide.
