App deep linking with goo.gl
Blog post from Google Cloud
Starting in 2015, goo.gl short links were enhanced to serve as versatile links that direct users to the appropriate content across Android apps, iOS apps, or websites, depending on their platform and app installation status. By setting up App Indexing for both Android and iOS, these URLs enable seamless redirecting, ensuring that users with the app installed are taken to the app's specific page, while others are guided to the website. This feature not only applies to new URLs but also retroactively to existing ones, offering improved re-engagement opportunities for app users. Integrating the URL Shortener API into an app's share flow further enhances this capability, allowing links shared across platforms to automatically direct to the native app. Google Maps exemplifies this functionality by generating links that optimize the sharing experience regardless of the user's platform. For developers, deep linking via goo.gl is accessible to all iOS developers, offering a broader reach compared to search-based deep links.
