What is deferred deep linking?
Deferred deep linking is essentially deep linking with a memory. A deferred deep link works as a deep linking — linking to a specific page or screen in your app — even if someone doesn’t have your app installed yet.
In that scenario, they will be taken first to the App Store or Google Play, where they can install your app. After installing, the first open of your app will take them to the desired location in your app.
So deferred deep linking is basically just deep linking, deferred until after someone actually downloads your app. This is a must if you are running ads with deeplinks that are also targeting users who don’t have the app installed.
Deferred deep links rely on mobile attribution, connecting a user to the last click before the app install and providing the deeplink that was attached to this click.
