OneLink™ overview

At a glance: Many app owners have owned media assets such as websites, banners, social media posts, user emails, and telephone numbers. OneLink is a single link technology that converts owned media users into mobile app users, regardless of device, operating system, channel, or platform.

About OneLink

  • Helps marketers engage their users by providing links that work across all owned media marketing channels. 
  • Redirects users to the correct app store (e.g. App Store or Google Play), landing page, or app (if users already have the app installed).
  • Opens the app to the default activity (using App Links, Universal Links, and URI scheme, as set in the OneLink template). 
  • Drastically increases user engagements and conversions by deep linking existing users, or by using deferred deep linking for new users, to specific content and experiences within the app (as set in the OneLink custom link and implemented by the developer).
  • OneLink setup has 2 components: A OneLink template, and a OneLink custom link.
  • A OneLink template represents the routing logic at the core of your links, to redirect users to the correct app store and open the app. A OneLink template is not a clickable link for your end-users; it is the foundation for generating many custom links. Based on the template, you can create many OneLink custom links for the users to click on. A single OneLink template can be the basis for creating many links. It is rare to need more than one or two OneLink templates in the lifetime of an app (outside of testing).
  • Free of charge to all account plans.
