Deferred deep linking is one aspect of mobile deep linking. It describes the principle of deep linking into an app that is not yet installed. This implies that clicking (or otherwise invoking) the deep link causes:

Contents

  1. An app store to open to enable the end-user to install the linked-to app
  2. Once the app is installed, the link is invoked with its original URL and parameters so that the newly installed app can handle the invocation.

A common use case is to drive installs; linking to functionality in a not-yet-installed app provides the user with an incentive to install it.

Platform-provided support

While there is currently no industry standard for deferred deep linking, various platform providers offer differing levels of support:

  • Apple iOS: No support.
  • Android support on the Google Play store: Google gives app developers the option of passing the original deep link through the Google Play App Store using the Intent: "The deep link should take users directly to the content, without any prompts, interstitial pages, or logins. Make sure that users can see the app content even if they never previously opened the application.”
  • Android support on non-Google app stores: No support. This is the majority of Android app installations, since Google Play makes up less than 1/4 of the volume of Android apps downloaded.
  • Installs driven by Facebook ads: Developers can bring users to the content inside the installed app with using Facebook's Deep Linking for Mobile Install Ads technology: "When a person taps on a mobile app install ad on Facebook, the developer can choose to send them to a specific place in their app after it's downloaded, such as a product page rather than the homepage."

    • Alternatives to Platform-provided support

    For the platforms where there is no real support (the majority), the only option is a "roll-your-own" approach. The general approach is to provide a mechanism where the URL and its parameters can be passed "around" the app store; ie. received from the source (linking) application (the "click"), stored, and then passed to the destination (linked-to) application once it's installed and run.

    The major technical challenge to solve in this approach is identifying which click caused which install so that the correct URL and parameters can be passed to newly-installed app. Tying clicks to installs is a family of technologies known as Attribution.
