Remarketing campaigns serve to re-target the existing project audience. One example would be displaying an ad to users who have not used your app for longer than 30 days. When the user clicks on the ad's link, it launches the app, but instead of the home screen, the user is taken to the page that corresponds to the specified deep link.
Deep links are a type of URL that takes people to a specific page in an app. For more details, refer to Deeplinks.

Click Calculate.
