Quick Answer
A deep link is a URL that takes users directly to a specific page, product, or screen inside a mobile app — bypassing the app’s homepage entirely. Instead of landing on the front door of an app, a deep link opens the exact content the user was expecting. For example, a deep link to an Amazon product opens that product page inside the Amazon app, not the Amazon homepage. There are three main types: traditional deep links (URI schemes), Universal Links (iOS), and App Links (Android). Deep links are used everywhere — in affiliate marketing, social media campaigns, email flows, push notifications, and ads — because they dramatically improve conversion rates compared to regular links. Since Firebase Dynamic Links shut down in August 2025, many brands and creators are migrating to alternatives like JotURL to handle their deep linking needs.
If you’ve ever clicked a link on Instagram and landed exactly on the product you wanted inside the Amazon app — not the homepage, not a browser — that was a deep link at work. It felt seamless, almost invisible. That’s exactly the point.
Deep linking is one of the most powerful but least understood tools in digital marketing. When done right, it removes friction from the user journey and turns more clicks into actual conversions. When ignored, it sends people to wrong places, breaks app experiences, and leaks revenue.
This guide explains everything: what deep links are, the different types, how they work technically, why they matter for marketers and creators, and how to create them — without needing a developer.
What Is a Deep Link?
A deep link is a URL that points to a specific destination inside a mobile app, rather than just opening the app or a generic webpage. The “deep” in deep link refers to going deeper into an app’s content structure — past the entry point, directly to the relevant screen.
Think of a regular link like knocking on the front door of a building. A deep link is having a key to go directly to the office you need, on the exact floor, without stopping at reception. Deep links are used by:
Affiliate marketers and influencers — linking followers directly to products inside shopping apps like Amazon, Target, or Walmart.
App developers — linking to specific screens within their own apps from ads, emails, or social posts.
Brands and e-commerce — reducing drop-off by sending paid traffic directly to landing pages inside apps.
Content creators — making it easy for their audience to complete purchases without extra navigation.
How Do Deep Links Work?
When a user clicks a deep link, the device checks whether the target app is installed. Based on the result, two things can happen:
If the app is installed: The link opens the app and navigates directly to the specified content — the product page, the video, the checkout — without any manual navigation required.
If the app is not installed: A standard deep link typically fails or opens the app store. More advanced deep link types (called deferred deep links) can solve this by first sending the user to install the app, then delivering them to the right content after installation.
This behavior differs depending on the type of deep link being used.
The 3 Types of Deep Links
Understanding the different types helps you choose the right approach for your use case.
1. Traditional Deep Links (URI Schemes)
URI scheme deep links use a custom protocol like amazon:// or instagram:// to open a specific app and navigate to content. They’re the oldest form of deep linking.
Pros: Simple to create, widely supported. Cons: If the app isn’t installed, the link usually breaks or throws an error. They don’t provide a fallback to the web. They also don’t work reliably across all iOS and Android versions.
Best for: Internal app navigation, where you know the user has the app installed.
2. Universal Links (iOS) and App Links (Android)
Apple’s Universal Links and Google’s App Links are the modern standard for deep linking. They use standard HTTPS URLs — the same URLs you’d use for a website — and the operating system decides whether to open the app or the browser.
How they work: – The app developer creates a special configuration file hosted on their domain (apple-app-site-association for iOS, assetlinks.json for Android) – When a user clicks the link, iOS or Android checks this file – If the app is installed, the app opens; if not, the website opens as a fallback.
Pros: Seamless user experience, reliable fallback to web, works without errors if the app isn’t installed. Cons: Requires setup by developers on both the app and server sides.
3. Deferred Deep Links
Deferred deep links are the most powerful type. They work even when the user doesn’t have the app installed yet. Here’s the flow:
- User clicks a deep link
- App is not installed → user is sent to the App Store or Google Play
- User downloads and installs the app
- App opens and takes the user directly to the content they originally clicked.
This is particularly valuable for marketing campaigns targeting new app users — the deep link intent is “deferred” until after installation, then delivered.
Best for: User acquisition campaigns, influencer marketing for apps, and re-engagement.

Why Deep Links Matter for Marketing
The business case for deep linking is straightforward: people convert more when they experience less friction. Every extra step between a user clicking your link and completing an action (a purchase, a signup, a view) costs you conversions.
Deep links directly reduce that friction. The impact is measurable:
- Higher conversion rates — sending users directly to a product page inside an app typically outperforms sending them to a mobile web page.
- Better user experience — users expect app experiences when they’re on mobile; a browser redirect feels broken.
- More accurate attribution — deep link platforms track exactly which link drove which action, in which app, on which device.
- Lower bounce rates — when users land where they expected to land, they don’t bounce.
For affiliate marketers specifically, deep links are non-negotiable. If you’re promoting Amazon products on Instagram and your link opens a browser instead of the Amazon app, you’re losing a significant portion of your commissions to friction.
Deep Linking After Firebase Dynamic Links Shutdown
In August 2025, Google shut down Firebase Dynamic Links — one of the most widely used deep linking platforms. Millions of apps and marketing campaigns that relied on Firebase were forced to find alternatives immediately.
This created both a challenge and an opportunity. The challenge: brands and developers needed to migrate quickly. The opportunity: newer platforms built specifically for marketers (not just developers) filled the gap with solutions that are easier to use and often more powerful.
JotURL’s Easy Deep Linking tool was built exactly for this: creating deep links to 70+ apps — including Amazon, Instagram, TikTok, Target, Walmart, LTK, and more — without writing a single line of code. You paste your affiliate or product URL, JotURL generates the deep link, and your audience lands directly inside the right app.
Deep Links in Affiliate Marketing
Affiliate marketing is one of the highest-value use cases for deep linking. Here’s why it matters and how it works:
The problem without deep links: An influencer shares a link to a product. The follower clicks it on mobile. Instead of opening the Amazon app, it opens a mobile browser. The checkout process is clunky compared to the app. Many users abandon before purchasing, and the influencer loses the commission.
With deep links: The same click opens the Amazon app directly on the product page. The user is already logged in. One tap and the order is placed. Conversion complete.
JotURL’s Easy Deep Link feature supports the most important affiliate platforms for creators: – Deep link to Amazon – Deep link to LTK – Deep link to Target – Deep link to Walmart – Deep link to Instagram – Deep link to TikTok
How to Create a Deep Link (Without a Developer)
Traditional deep link setup requires developer work: configuring app-side settings, hosting configuration files, and managing fallback logic. That’s not realistic for most marketers and creators. JotURL simplifies this entirely with three methods: manually through the Dashboard, via the Chrome Extension, or in bulk through the API Lab.
Method 1: JotURL Dashboard
Step 1: Copy the destination URL from the app you want to deep link to — for example, an Amazon product page or affiliate link.
Step 2: Go to your JotURL Dashboard and click the (+) button to create a new Tracking Link. Paste the URL as the Destination URL. JotURL automatically recognizes the domain and configures the deep link — no need to select the app manually.
Step 3: Optionally, add a branded domain and tags to organize your links.
Step 4: Click the green Save button. Your deep link is ready to copy and share anywhere — Instagram bios, TikTok posts, emails, YouTube descriptions, or stories.
Method 2: Chrome Extension
Download the JotURL Chrome Extension to create deep links directly from your browser, without opening the Dashboard, while browsing any product page.
Method 3: API Lab (Bulk)
If you have hundreds of affiliate links to convert, use JotURL’s API Lab. Upload an Excel file following JotURL’s template, and the automation generates all your deep links at once.
Deep Linking vs. Regular Links: The Key Differences
| Feature | Regular Link | Deep Link |
| Opens app on mobile? | ❌ Usually opens browser | ✅ Opens app directly |
| Goes to specific content? | ❌ Often homepage | ✅ Exact page/product |
| Works if app not installed? | ✅ Opens web | Depends on type |
| Conversion rate | Lower | Higher |
| Setup complexity | None | Low–Medium |
| Best for | Desktop/general | Mobile marketing |
Deep Links vs. Vanity URLs vs. Short Links
These terms are often confused. They’re related but serve different purposes:
Deep links route users to specific in-app content. Their focus is the destination.
Vanity URLs are branded, memorable short links (like yourbrand.com/sale). Their focus is on branding and memorability.
Short links compress long URLs for sharing. Their focus is on length and cleanliness.
JotURL combines all three — you can create a branded short link that is also a deep link, giving you the tracking, the branding, and the in-app routing in a single URL.
Common Deep Linking Mistakes
Using URI schemes only — without Universal Link / App Link fallbacks, your deep links break for users who don’t have the app installed. Always use a platform that handles fallbacks automatically.
Not testing across devices — deep link behavior differs between iOS and Android, and between different app versions. Test your links on both platforms before publishing.
Ignoring tracking — deep links without tracking are a missed opportunity. Good deep link platforms (like JotURL) show you exactly how many people clicked, what device they used, and whether they converted.
Not updating links when URLs change — if a product URL changes and you’ve hardcoded the destination, all your old links break. Using a managed platform like JotURL lets you update the destination without changing the link itself.
Frequently Asked Questions
What is a deep link in simple terms?
A deep link is a URL that takes you directly to specific content inside an app, instead of opening the app’s home screen or a generic website. When you click a deep link on your phone, and it opens the exact product page inside the Amazon app — not a browser, not the Amazon homepage — that’s a deep link. They make the mobile experience smoother and faster by skipping unnecessary navigation steps.
What is the difference between a deep link and a regular link?
A regular link typically opens a webpage in a browser, even on mobile. A deep link detects that a user is on mobile, checks whether the app is installed, and opens the app directly at the relevant content. The user experience is significantly better — it’s faster, more native, and requires fewer steps to complete an action. For marketers, this translates directly to higher conversion rates.
What happened to Firebase Dynamic Links?
Google shut down Firebase Dynamic Links in August 2025. It was one of the most widely used deep linking solutions for mobile apps. Brands and developers who relied on it were forced to migrate to alternative platforms. JotURL’s Advanced Deep Linking tool is one of the most popular alternatives, particularly for enterprises, app owners, and developers who need attribution and custom app routing.
Are deep links free to create?
It depends on the platform. JotURL offers a 14-day free trial that allows you to create deep links and test the functionality. Paid plans unlock higher click volumes, branded custom domains, advanced analytics, and access to all 70+ supported apps. You can explore all options at joturl.com/pricing.
What apps support deep linking?
Most major apps support deep linking to some extent. JotURL’s Easy Deep Link feature supports 70+ apps, including Amazon, Instagram, TikTok, Snapchat, YouTube, Target, Walmart, LTK, Mavely, and many more. The level of deep link support varies by app — some allow very specific destination targeting (exact product pages), while others support more general in-app destinations.
Do deep links work when the app isn’t installed?
It depends on the deep link type. Basic URI scheme deep links typically fail if the app isn’t installed. Universal Links (iOS) and App Links (Android) fall back gracefully to the web version. Deferred deep links go even further — they remember the user’s intended destination and deliver them there after they install the app. JotURL’s smart links handle fallbacks automatically based on the user’s device and app installation status.
What is a deferred deep link?
A deferred deep link preserves a user’s intended destination through the app installation process. If someone clicks a link to a specific product but doesn’t have the app installed, a deferred deep link sends them to the App Store or Google Play to download the app — and then, after installation, automatically opens the exact content they originally clicked. This is particularly valuable for user acquisition campaigns.
How do deep links improve affiliate marketing?
Affiliate marketers who use deep links instead of regular links typically see higher conversion rates. The reason is simple: when a mobile user clicks an affiliate link, and it opens directly inside the shopping app (Amazon, Target, etc.) rather than a mobile browser, they’re already in the native shopping environment where they’re most likely to complete a purchase. They’re already logged in, their payment info is saved, and checkout is one or two taps away. All of that friction that regular links create — loading a browser, logging in, navigating to the product — is eliminated.
Conclusion
Deep links are the difference between a click that converts and a click that bounces. Whether you’re an affiliate creator, a brand marketer, or an app developer, understanding how deep linking works — and using the right tools to create it — is one of the highest-ROI investments you can make in your mobile marketing stack.
With Firebase Dynamic Links now gone, the window to migrate to a better, more marketer-friendly solution is wide open. JotURL’s Easy Deep Linking tool makes it fast and code-free. Start for free at joturl.com and see the difference a well-placed deep link makes.
