Find out if you have deep linking enabled
Android App Links
Have your Android developer follow the steps in this article to test whether a particular URL is enabled for App Links. If the green checkbox is visible, then App Links are enabled.
iOS Universal Links
Enter a URL to test in Apple's App Search API Validation Tool, and check the "Link to Application" section. If the status says "Passed," Universal Links are enabled.
Optimizing conversions with deep links
Deep links that align well with creative assets, the bidding event, and the audience targeted, and that send people to the most relevant app pages to help them complete their desired actions, will drive the most conversions.
Implementing large numbers of deep links in your apps
If you have 100 app pages, you don’t necessarily have to implement 100 deep links in your app. Instead, you can implement App Links or Custom Schemes with wildcards. For example, the link “*.example.com” can be used for both “test1.example.com” and “test2.example.com” URLs. Learn more about using wildcards
