What is the difference between deep linking and standard linking?

A standard link opens an app's home screen or a website's homepage. A deep link, on the other hand, routes the user to a specific piece of content inside the app—such as a product page, a user profile, or a promotional offer—skipping all intermediate navigation steps.

Does deep linking work if the user hasn't installed the app?

Yes, through a technique called deferred deep linking. When a user clicks a deep link without having the app installed, they are first redirected to the app store. After installation and first launch, the app automatically opens the originally intended content, preserving the user's context and intent.

Mobile Deep Linking: Guide Users to the Right App Content

What Is Mobile Deep Linking?

Mobile deep linking is a technique that directs users to a specific page or piece of content inside a mobile app, rather than simply opening the app’s home screen. Think of it as the mobile equivalent of a direct URL on the web.

Without deep linking, a user who clicks a promotional link for a pair of sneakers might land on the app’s main page—and then have to search for the product manually. With deep linking, they land directly on the sneaker product page. The difference in user experience is enormous.

Why Deep Linking Matters for Engagement and Conversions

Friction kills conversions. Every extra tap a user has to make reduces the likelihood they’ll complete an action. Research from Branch.io shows that deep-linked users convert at rates up to 66% higher than users who land on a generic home screen.

Here’s why deep linking is a game-changer:

Reduced drop-off: Users get what they want instantly, so they stay longer.
Better retargeting: Email and push notification campaigns become far more effective when each link goes to the exact relevant content.
Improved attribution: Marketers can track which links drive installs, purchases, and engagement with precision.
Seamless cross-channel journeys: A link shared on social media, SMS, or email all leads to the same in-app destination.

For e-commerce brands, this is particularly impactful. Imagine sending an abandoned cart notification that opens the cart directly in the app—not the homepage.

The Three Types of Deep Links

Standard Deep Links

These work only if the app is already installed. They use URI schemes (e.g., myapp://product/12345) to open a specific screen. The limitation? If the app isn’t installed, the link fails entirely.

Deferred Deep Links

Deferred deep links solve the installation gap. When a user without the app clicks the link, they’re sent to the App Store or Google Play first. After installing and opening the app, they’re automatically routed to the original content. This is critical for acquisition campaigns.

Contextual Deep Links

These carry additional metadata—like a referral code, a user ID, or campaign source. They enable personalized onboarding experiences. For example, a user who clicks a friend’s referral link could see a personalized welcome message with both names after installation.

How to Implement Deep Linking: A Practical Overview

Implementation depends on your platform and tech stack, but the core steps are consistent:

Configure Universal Links (iOS) and App Links (Android): These are the modern, secure standards that replaced older URI schemes. They use standard HTTPS URLs verified by your domain.
Host an association file: Apple requires an apple-app-site-association file; Android requires a assetlinks.json file, both hosted on your web server.
Handle incoming links in your app code: Your app needs logic to parse the URL and navigate to the correct screen.
Use a deep linking platform (optional but recommended): Tools like Branch, Adjust, or AppsFlyer simplify implementation, add deferred linking, and provide analytics dashboards.

At Lueur Externe, we regularly configure deep linking architectures for clients running complex mobile and e-commerce ecosystems—ensuring links work flawlessly across iOS, Android, and web fallback scenarios.

Common Pitfalls to Avoid

Broken fallback behavior: Always define what happens if the app isn’t installed. A blank screen or error page destroys trust.
Ignoring Android App Links verification: Unverified links trigger a disambiguation dialog, adding unnecessary friction.
Not testing across devices and OS versions: Deep link behavior can vary significantly between iOS 17 and iOS 15, or between Samsung and Pixel devices.
Forgetting web-to-app banners: Smart banners on your mobile site can intercept visits and suggest opening the content in the app via deep link.

Real-World Example: E-commerce Push Notification

Consider an online fashion retailer using Prestashop for their web store and a native app for mobile. A customer browses a jacket on the website but doesn’t purchase. The next day, a push notification says: “Your jacket is now 20% off.”

Without deep linking, the user opens the app and sees the homepage. With deep linking, the notification opens the exact jacket product page with the discount already applied. The result? A dramatically shorter path to purchase.

Conclusion: Make Every Link Count

Mobile deep linking isn’t a nice-to-have—it’s a fundamental part of any serious mobile strategy. It reduces friction, increases conversions, and creates the seamless experiences users now expect.

Whether you’re launching a new app or optimizing an existing mobile ecosystem, getting deep linking right requires technical precision and strategic thinking. Lueur Externe, with over 20 years of expertise in web and mobile development, can help you implement a robust deep linking strategy tailored to your platform and business goals.
