# Universal Links

Deeplinks (Or Universal Links) is a useful feature for associating your website domain with your mobile native app. Also, your users will be able to click a deep URL (Url with some path or parameter), and they will be redirected to the same page in the app.

## iOS

[Universal Links](https://www.singular.net/glossary/universal-links/) are Apple’s deep linking technology, designed to replace the older URI-scheme deep linking method. They are available for devices running iOS 9 and above.

{% hint style="warning" %}
On iOS 14 and later, Apple’s CDN retrieves and caches the AASA file. When your app is installed, devices download the file from the CDN immediately. Devices check for updates approximately once per week after app installation. To download a newer version of the AASA file, reinstall the app. There is no direct CDN invalidation option.
{% endhint %}

While Universal Links allow for deep linking behavior similar to URI schemes, they function very differently behind the scenes. Universal Links look like normal HTTPS URLs, e.g. “<https://www.linkedin.com”>. When a user clicks a Universal Click, the user’s device opens the app that the link was configured for. If the app is not installed on the device, the user is taken to the actual URL in their mobile browser.

{% hint style="warning" %}
It is up to third-party web browsers to enable universal links functionality. Universal links may not be enabled in every web browser. For information about other browsers, please check with the browser’s vendor. Safari implements all of the function described in this technote.
