Definition
Deep Linking enables direct navigation to specific in-app content via URLs. Universal Links (Apple) and App Links (Android) improve user re-engagement and paid campaign CVR by directing users to relevant content post-install. Deferred deep linking handles pre-install paths (install-then-navigate).
How It Works
Apple App Store (Universal Links)
- URLs mapped to specific app screens via entitlements file
- Tapped links open app directly (seamless experience)
- NSUserActivity enables deep link + Spotlight indexing
- Example:
example.com/product/123→ app opens product detail for ID 123
Google Play Store (App Links)
- URLs verified via .well-known/assetlinks.json file
- Android 6.0+ opens app for matching links (no disambiguation dialog)
- intents route URLs to specific activities
- Example:
example.com/product/456→ app opens product detail for ID 456
Amazon Appstore
- Limited deep link support; URI schemes primary method
Formulas & Metrics
CVR Boost from Deep Linking:
- Web traffic → app with deep link: +20–40% CVR
- Paid campaigns with deep links: +15–30% CVR improvement
- Re-engagement (push notification with deep link): +40–70% click-to-action
Best Practices
- Universal Links: Certificate + entitlements + backend URL verification (Apple)
- App Links: APK signing + assetlinks.json validation (Google)
- Deferred Deep Linking: Firebase Dynamic Links or alternative (handles install → navigate flow)
- Paid Campaigns: Always use deep links (e.g., promo code page, specific product)
Examples
- Gaming App: Deep link to specific tournament. Push notification "Join Tournament #5" → deep link → CVR +50%
- E-commerce: Deep link to product. Google Search result "Buy Widget" → deep link → installs +25%
