What is Deep Linking?

Definition and Introduction to Deep Linking

Deep linking refers to the technology that enables links to direct a user to a specific, targeted app content, whether or not the app is already installed.

Unlike traditional web links that route users to the homepage of a website, a deep link can take users directly to a designated location within an app, be it a mobile game level, a shopping cart, or any other in-app page.

Deep linking serves as a bridge between the web and apps, ensuring a seamless user experience by eliminating the cumbersome steps of launching an app and searching for specific content. Imagine clicking on a promotional link for a product and being taken straight to that product’s page within an app. This is the power of deep linking in action.

Furthermore, with the evolution of mobile deep linking, the distinction between web and app content has blurred.

Now, if an iOS or Android app supports deep linking and is installed on the user’s device, a click on a deep link will open the appropriate section of the app. If not, it might redirect users to the app store to download the app or provide an alternative web link.

This dynamic approach, known as deferred deep linking, underscores the adaptability and user-centric nature of the technology.

Types of Deep Linking

Deep linking is not a one-size-fits-all solution; it comes in various forms, each serving unique purposes in the mobile app and web landscapes. By understanding the different types of deep linking, developers, and marketers can optimize the user experience and create more effective engagement strategies. Let’s explore these types:

1. Traditional Deep Linking

This form of deep linking requires the app to be already installed on a user’s device. When a user clicks on a deep link, the app opens directly to the specified content. If the app isn’t installed, the link may either result in an error or redirect users to a web browser page.

2. Deferred Deep Linking

Unlike traditional deep linking, deferred deep linking works even if the app is not installed. When a user without the app clicks on the link, they’re first directed to the app store to download the app. Once installed, the app launches immediately to the specific content the link pointed to, ensuring a seamless onboarding experience.

3. Universal Linking (iOS) and App Links (Android)

Introduced by Apple and Google, respectively, these are the original forms of deep linking for mobile apps. Depending on whether the app is installed, they allow deep links to open in either the app or a web browser. iOS 9 brought Apple Universal Links, and Google built App Links as the Android equivalent. They aim to provide a consistent user experience by smartly redirecting users.

4. Custom URI Scheme Deep Links

Custom URI (Uniform Resource Identifier) schemes were used before universal linking and app links. These are unique to each app, allowing it to be launched from both the web and other apps. However, they don’t have the fallback capabilities of newer deep-linking methods.

How does Deep Linking in Mobile Apps work?

Deep linking offers a tailored bridge between the web and mobile apps, but its implementation varies slightly between Android and iOS platforms. 

On the Android front, “App Links” are used, which automatically direct users to the relevant app content when they click a link. If the Android app isn’t installed, the user is redirected to the Play Store or a web page.

Conversely, for iOS, Apple introduced “Universal Links” starting from iOS 9. These links function seamlessly, directing users to in-app content when the app is installed. If not, they lead the user to the App Store or a mobile web page.

Benefits of Deep Linking

Deep linking is much more than just a technical term; it’s a strategy that transforms user experience and app engagement. Let’s delve into the advantages it offers:

1. Improved User Experience: Deep linking offers a seamless user experience. Instead of being directed to a home page or an app’s main screen, users are taken directly to the specific content they’re interested in, whether it’s inside an app or on a mobile web page.
2. Increased App Engagement: Deep linking fosters greater interaction by leading users directly to in-app content from external sources. This directness means users are more likely to engage with the app, view more pages, and explore more.
3. Enhanced App Onboarding: Deep linking can streamline the onboarding process for new app users. If they click a deep link but don’t have the app installed, they’re redirected to the app store or Play Store, encouraging download and subsequent interaction.
4. Effective Marketing and Retargeting: Deep linking allows advertisers to drive users directly to a specific page within an app, making promotional campaigns more targeted and efficient. This can be particularly effective for retargeting users, drawing them back into the app to complete an action they may have previously abandoned.
5. Support for Multiple Platforms: With deep linking solutions like deferred deep linking, it doesn’t matter if the user has the app installed or not. The experience remains consistent, whether on Android or iOS, ensuring users get the content they desire, enhancing their overall journey.

Challenges with Deep Linking

While deep linking has reshaped the mobile user experience and enhanced app engagement, it’s not without its challenges.

One primary concern is the fragmentation between Android and iOS platforms. For instance, while Android app links and iOS universal links offer similar functionality, their implementation and setup can differ, potentially causing inconsistency in the user experience.

Another challenge is managing deferred deep linking. If users without the app click on a deep link, they might be redirected to the app store. Still, ensuring they land on the exact in-app content post-install can be technically intricate.

Moreover, creating deep links requires meticulous configuration to ensure they lead to the right app content, preventing broken or irrelevant links. Lastly, as deep linking technology advances, keeping up with new changes and updates is crucial for app development teams.

Final Thoughts

As technology evolves, we can anticipate even more seamless mobile experiences, driving users directly to specific content with precision. In conjunction with evolving user experience trends and app development advancements, deep linking for mobile apps will undeniably shape how users engage with content. Apple, Google, and other industry leaders will likely steer this transformative aspect of mobile web interaction, refining deep linking’s potential.

FAQs on Deep Linking

What is the primary difference between deferred deep linking and traditional deep linking?

Deferred deep linking allows users without the app to be taken directly to specific content once they download the app. However, Traditional deep linking requires the app to be installed for the link to work effectively.

How do iOS Universal Links differ from Android App Links?

While both iOS Universal Links and Android App Links aim to provide a seamless user experience by directing users to app content, iOS Universal Links are designed for iOS 9 and above, whereas Android App Links are Google’s solution for Android apps, acting as the Android equivalent.

Can deep linking drive app engagement and improve the onboarding experience?

Absolutely! Deep linking allows for a more seamless mobile experience by taking users directly to specific content inside an app, enhancing the onboarding experience, and promoting increased engagement.

How does deep linking functionality interact with links in mobile web browsers?

When a user clicks a link in a mobile web browser that has deep linking functionality, they can be redirected to a specific page within an app if it’s installed or to the app store or Play Store if it isn’t, thereby bridging the gap between web and app content.

Are there tools to create mobile deep links that support Android and iOS?

Yes, various deep linking solutions in the market support deep links for mobile across both Android and iOS, ensuring a consistent user experience regardless of the device.
