Universal Links are Apple’s method for opening specific in app content directly from a standard web URL on iOS. They create a smooth and reliable path from a website, message, or ad into the matching location inside an app. If the app is not installed, the link loads the website or the App Store first, then guides the user to the right content once the app is available.
Universal Links were introduced to solve the limitations of older deep linking methods and to give users a consistent and secure experience across iOS devices.
Universal Links are regular HTTP or HTTPS URLs that iOS recognizes as linked to a specific mobile app. When a user taps one of these links, the operating system checks whether the app that claims the associated domain is installed.
If the app exists, iOS opens it directly at the correct in app destination.
If the app is missing, the link loads the website instead or redirects to the App Store.
Universal Links give developers and marketers one link that works across browsers, channels, and devices, without pop ups or error messages.
The term deep links refers to any link that leads a user to a specific location inside an app or website. Universal Links are the iOS version of deep links. Android uses a similar standard called App Links.
Here is the essential difference:
Legacy deep link
Custom scheme such as myapp://product?id=43
This works only if the app is already installed. If not, users see an error or nothing happens.
Universal Link
Standard URL such as https://myapp.com/product/43
This works in all cases. If the app is installed it opens the app. If not it loads the website or the App Store.
Universal Links remove the uncertainty that custom schemes created and give users a predictable path every time.
Universal Links send people exactly where they expect to go. No modal errors. No blank screens. No confusing redirects.
When users open the correct in app content immediately, they skip extra steps. This leads to more purchases, more sign ups, and more engagement.
A smooth experience helps bring users back. Universal Links reduce friction and help people re enter the app through saved items, promotions, reminders, or personalized content.
Universal Links work through verified domain ownership. This prevents malicious apps from trying to claim your links or hijack user traffic.
If users do not have the app, they still reach relevant content through the browser or the App Store.
To enable Universal Links, an app developer must follow two key steps:
When a user taps a Universal Link, iOS checks:
If everything matches, the user is taken directly to the in app content.
Some apps never allow Universal Links to open external apps. Examples include certain social media apps and in app webviews. In those environments, the fallback website will open.
Email service providers and ad networks often wrap links in redirect URLs to run click tracking. These redirects break Universal Links unless the provider supports a safe integration.
Users can accidentally disable the feature for a domain by tapping the option to open in browser. Re enabling it is possible but rarely done by users.
A missing or malformed association file can prevent Universal Links from working entirely.
Marketers and growth teams typically track:
Click through rate
How many people tap the link compared to how many saw it.
Conversion rate
How many complete the intended action after tapping the link.
How many continue engaging after arriving via a Universal Link.
In app engagement metrics
Session length, viewed items, repeat visits, and other behavior signals.
These metrics show whether Universal Links help reduce friction and support the customer journey.
They are supported on iOS 9 and later.
No. Some apps override or block them. In those cases only the website opens.
Universal Links can support deferred deep linking but they do not perform it by default. Deferred deep linking requires additional configuration on the app side.
Yes, but only when the app is not installed.
No. iOS requires verified domain ownership, so only one app can claim a domain.
