What Is a Deep Link?
6 min read
A deep link is a URL that points to a specific location inside a mobile app rather than to a website. Tap one and, instead of a web page loading in a browser, the app opens directly to the exact screen the link references — a video, a product, a profile, or a post. This guide explains deep links in plain English and shows where they fit for creators and marketers.
Deep link vs. a normal web link
A normal web link (https://www.youtube.com/watch?v=...) opens in a browser. On a phone, when that link is tapped from inside an app like Instagram, it often opens in that app's built-in browser — a stripped-down view where the user is not logged in and many features are missing.
A deep link instead tells the operating system to hand the destination to the right native app. The user lands inside YouTube, TikTok, Amazon, or Instagram itself, already signed in, with full functionality.
The main types of deep links
There are three terms worth knowing, and they are often confused:
- Standard deep link — opens a specific screen in an app, but only works if the app is already installed.
- Deferred deep link — if the app is not installed, it sends the user to the app store first, then opens the right screen after install.
- Universal link / App Link — a single https URL that opens the app when installed and falls back to the website when it is not (Apple calls these Universal Links, Android calls them App Links).
How a deep link actually opens an app
On Android, deep links commonly use an intent:// URL that names the target app's package (for example, com.google.android.youtube for YouTube). The system matches that intent to the installed app and opens it, with a web fallback if the app is missing.
On iOS, apps register custom URL schemes (like twitter://) and Universal Links. Apple is stricter about when an app can be opened from another app, which is why deep linking is more reliable on Android than on iPhone.
Why creators and marketers use deep links
Opening content in the native app removes friction. Users are already logged in, autoplay works, and add-to-cart or follow actions take one tap. That typically means higher engagement and conversions than sending people through an in-app browser.
