What Is Deep Linking?
Mobile Deep Linking
Deep linking opens a specific page or content within a mobile app instead of just launching the app's home screen. Universal Links (iOS) and App Links (Android) let web URLs open directly in the associated app. Deferred deep links work even if the app isn't installed yet.
How Deep Linking Works
A user clicks a product link in an email: example.com/product/123. If the app is installed, it opens directly to product 123 inside the app. If not installed, the user goes to the web page (or app store) and after installing, the app opens to product 123. This is deferred deep linking.
Key Concepts
- Universal Links (iOS) — Apple's system linking web URLs to specific app screens — requires apple-app-site-association file
- App Links (Android) — Google's system for verified deep links — requires assetlinks.json digital asset links file
