You've probably felt at some point that the path between clicking on an ad and reaching the exact product within an app is a real maze. To solve this, there are... deep linksThis technology allows you to skip an app's home screen and land directly on the content you're interested in, improving retention and making the user experience much smoother.
However, the landscape has changed drastically because Google has decided to put an expiration date on its flagship tool, Firebase Dynamic LinksThis has left countless developers and marketing teams scrambling, searching for a solution that won't break their campaigns or frustrate users with 400 errors when trying to access their applications.
What is the difference between a Dynamic Link and a regular Deep Link?
To put it simply, a deep link is like a direct postal address to a room in a building, but it only works if you already have the key (the app installed). If you don't, the link simply won't work. It does nothing or gives an errorIn contrast, Dynamic Link is much smarter; it adapts to the user's context in real time.
- If the user accesses from a computer, the link sends them to the versión web.
- If you already have the app installed on your mobile, you can take it. directly to the specific section.
- If you don't have the app, it first redirects you to the Google Play Store or App Store And, after installation, it leaves it exactly where it was originally intended to be.
This ability to survive the installation process This is what makes them so powerful for ASO strategies, user acquisition, and sending push notifications, as they eliminate any friction in the conversion funnel.
How to set up Dynamic Links
To implement this technology, you first need to enable the service in the Firebase console and integrate the Dynamic Links SDK in the application code. Once configured, there are several paths to Create a shortcut on Android or specific routes depending on what we are looking for.
If we need simple links for a specific promotion, we can use the Firebase console to create them. static links with a custom suffix. But if the case is more complex, such as when we want to send the ID of a specific user to appear on a custom screen, the ideal solution is to use the Firebase REST API.
To generate these short links using the API, you must make a POST request to the Google APIs URL using the Web API KeyIn the body of the JSON, we define the domainUriPrefix (our registered domain), the link destination and package identifiers for Android (androidPackageName) e iOS (iosBundleIdThis allows the system to know exactly where to send the user based on their device.
The end of an era: the demise of Firebase Dynamic Links
This is where things get serious. Google has announced that the service will permanently shut down on August 25th, 2025From that point on, any link created with FDL will start returning a 400 error, meaning that all shortcut paths will break if the migration has not been completed in time.
If you currently depend on this system, you can't just stand idly by. It's crucial. planning migration well before the deadline to avoid losing attribution data or downloads. For those who decide not to use an immediate replacement, the most sensible thing to do is Remove the Firebase Dynamic Links SDK of the apps and clean the URL prefixes in the console to avoid erratic behavior.
Looking for the ideal replacement: Alternatives to the market
There's no single magic solution, as it depends on what you're using the links for. If you only need the app to install and redirect the user, then... deferred deep links They are the option. Tools like Branch or Adjust are very powerful in this segment, although unlike Firebase, they tend to have costs associated.
For those seeking a comprehensive alternative, EMMA presents itself as a solid option with its powlinksThese allow managing a single link for both operating systems, automatically recognizing the OS and directing the user to the corresponding store or to the app section if it is already installed, integrating the technology of App Links and Universal Links.
If the goal is purely campaign monitoring and analysis (such as knowing how many clicks come from an influencer or a QR code), there are tools available to advanced attribution which offer a much greater granularity than Firebase, allowing you to optimize your advertising investment based on real conversions.
Special cases and compatibility
It's important to mention that Firebase Dynamic Links was also used to ensure that clicks led users to a Instant app from Google Playpreventing them from opening in built-in browsers. To replicate this, you need to configure the parameter androidFallbackLink in the link, ensuring that the user experience is seamless regardless of whether the app is fully installed or running instantly.
Having your own domain is another competitive advantage. You can use custom domains such as links.example.com or free subdomains of page.linkAll analytics and statistics functions are compatible with these options, allowing you to maintain brand consistency while managing mobile traffic.
The transition to new deeplinking solutions is inevitable and requires a detailed analysis of the needs of each project, whether it involves seeking free native tools, paid solutions with advanced analytics, or the manual implementation of URL schemes in the Android Manifest file to efficiently redirect traffic.
