Deep Link
Deep Link
A link that opens a specific page or screen inside a website or app directly, instead of the homepage.
In Simple Terms
A deep link is a mechanism that opens a specific page or screen directly, whether on a website or inside an app. For example, if you're browsing a website on your phone and tap a button for a product, it might launch that shopping app and take you straight to the product page. Because it skips the homepage and jumps straight to the page you want, deep links are widely used across websites, mobile apps, and social media.
Behind the Name
The name comes from combining "deep" and "link" — instead of linking to a website's homepage, it links "deep" into a specific page or a specific screen buried within an app's structure. That's where the name comes from.
Take a Closer Look!
A deep link is a link that's set up to take you directly to a specific page inside a website or app.
Normally you'd land on the homepage first, but a deep link lets you open something like a specific product page right away.
Websites and apps handle this differently, and making it work inside an app requires special setup so the OS can recognize the link.
There are mainly two approaches to this.
- Older approach:
A setup (custom URL scheme) that only works if the app is installed — if it isn't, it just results in an error.
- Standard approach:
The OS-recommended standard approach (Universal Links or Android App Links), which opens the app if it's installed, or opens the corresponding web page if it isn't.
Real-world apps often combine both approaches depending on the situation.
There's also a mechanism called "deferred deep linking," which automatically guides users to the intended screen after they install the app from the app store, even if the app wasn't installed at the time they tapped the link. This works by recording the destination information on an external server ahead of time.
In this way, deep linking is a widely used and important technology for guiding users straight to where they want to go without making them get lost.
