Mobile App Ad Monetization: 3 Points Easy to Miss from an Engineering Perspective
The details you overlook are the ones that matter most.
Ad monetization for apps is a core revenue model for many app developers. DelightRoom, the company behind Alarmy, has also been growing rapidly through our own in-house ad monetization know-how.
However, as most app developers pursue ad monetization, they tend to focus solely on one-dimensional metrics like impressions, eCPM, and revenue, leaving other crucial elements easily overlooked. Even though these elements can have a massive impact on an app's ad revenue and user experience in the long run, many developers neglect them. Today, let's break down the things app developers frequently miss during the ad monetization process.
1. Issues in the Engineering and Deployment Process
Many developers make the mistake of treating ad-related changes more lightly than typical feature updates, rolling them out directly to all users without sufficient validation.
But mobile app ad monetization is a complex web of various ad SDKs and logic dictating when ads should appear. Entangled with the unique environment of app updates, deploying a bug can mean you're stuck unable to fix it until the next release—which is why these updates demand even more caution than other major feature deployments.
If a flawed ad monetization update is rolled out to 100% of your user base, the very first thing the developer faces is a loss of ad revenue. Ads that should load might not, leading to a failure to monetize, or worse, ad-related bugs might degrade the user experience. In the most severe cases, applying the wrong ad SDK or logic can cause app crashes, leading to the nightmare scenario of user churn.
To solve this, we need a better approach. First and foremost, you need to establish a QA process for ad-related changes that scrutinizes them just as rigorously—if not more so—than regular product specs. Sure, if your company is small, a heavy process might be too much, but you have to build at least a basic framework to prevent issues before they happen.
I also highly recommend utilizing phased rollouts. When distributing an app on Android or iOS through Google Play Console or App Store Connect, you can leverage features that gradually release the update to users. While the specifics differ between the two OS platforms, the core concept of a phased rollout is to release to a small number of users initially, then slowly ramp up the percentage to ensure app stability. If an issue arises, you simply halt the rollout at a low percentage and prepare the next build.
Leveraging A/B tests is also essential. No matter how high the probability of success for a change, unexpected issues can still crop up and negatively impact revenue. Using A/B tests lets you clearly compare and analyze the performance of your improvements. Even if an experiment has a bug, the revenue from your existing Control group is preserved, allowing you to build a much more stable deployment environment.
2. The Importance of Mediation and Ad Network SDK Version Management
Integrating mediation and ad network SDKs means a lot more than just adding a simple SDK. Generally, to elevate ad revenue, app developers tend to use not only mediation platforms but also install and run multiple ad networks side by side.
The critical point here is that mediation SDKs and ad network SDKs are connected via adapters and operate by passing data back and forth within the app. Because they are so intricately linked, the engineers behind each SDK naturally strive to support compatibility with the others.
However, since mediation platforms and ad networks are developed by different companies with different agendas, compatibility frequently breaks. For instance, if Network A releases a new version to support the latest mediation SDK, but Network B hasn't done any corresponding engineering for that mediation SDK version, you ultimately end up in a situation where those three SDK versions cannot be used together.
Consequently, to use three or more SDKs together, it's crucial to verify that all of them are mutually compatible and functioning well. Naturally, it's financially advantageous for developers to use multiple SDKs, but if you only focus on that and blindly install them, you'll suddenly find yourself facing dropping revenue and spiking crashes.
Honestly, an obvious drop in revenue or immediate crashes is the lucky scenario. You can simply halt the rollout, revert, stop the bleeding, and quickly find the root cause. The much bigger problem is when this revenue decline happens gradually, sending you on a slow downward spiral. Due to the nature of mediation, a lack of fill from a malfunctioning ad network gets picked up by other networks, making the change look gradual. When this happens, many companies fail to find the root cause and just give up, writing it off as a natural drop in demand.
With such massive risks lurking, you need to continuously and manually verify that each network integrates and plays nicely with the others when monetizing. Because one SDK update affects the rest, you have to do a full-sweep version check across all your SDKs to prevent bigger disasters. It's tedious, but checking them one by one is the path to maximizing revenue.
3. Poor Management of app-ads.txt and SKAdNetwork IDs
One of the most easily missed parts of ad monetization for many app developers is managing app-ads.txt and SKAdNetwork IDs. These might look like simple technical configurations, but they are actually critical factors directly tied to an app's ad revenue.
First, app-ads.txt is a text file that declares authorized ad sellers in the programmatic ad ecosystem. Introduced by the IAB Tech Lab as a standard to prevent ad fraud and ensure transparent transactions, missing or misconfiguring this file can cause serious problems. Advertisers' bids get restricted, which immediately leads to lower ad prices. Furthermore, your programmatic ad transaction volume could drop, or in the worst-case scenario, your inventory could be flagged as fraudulent, dealing a fatal blow to your ad revenue.
Similar to app-ads.txt, there is information you must manage exclusively for iOS: SKAdNetwork IDs. Since the iOS 14.5 update, SKAdNetwork has become the sole means to measure ad effectiveness while protecting privacy in the iOS environment. Proper management of SKAdNetwork IDs plays a core role in accurately measuring the performance of ad campaigns targeting iOS users and helping advertisers optimize those campaigns. This is how you optimize ad revenue on the iOS platform.
If you fail to manage SKAdNetwork IDs properly, inaccurate performance tracking for iOS ad campaigns will make optimization difficult, which ultimately can lead advertisers to slash their budgets. On top of that, growing doubts about your ad quality will erode advertiser trust, making it hard to build long-term partnerships.
To manage these two files effectively, you need a systematic approach. For app-ads.txt, it's essential to set up a regular monthly review schedule and immediately update the file whenever a new ad network partner is added. You can increase management efficiency by routinely syncing with your mediation partners and building an automated validation system.
For SKAdNetwork ID management, you must continuously maintain the latest ID lists for each ad network and regularly update your Info.plist file. When onboarding a new ad network, use a checklist to ensure nothing is missed, and rigorously track change histories via a version control system.
Finally, smooth communication with ad networks is crucial. Through regular partner meetings, you should swiftly respond to new policies or requirements and secure a direct contact channel for quick resolutions when problems pop up. It's best to establish a documented communication process to systematically manage all changes.
This kind of technical management might look basic, but it's becoming increasingly critical in the programmatic ad ecosystem. Especially with the rising demand for privacy protection and the growing importance of ad fraud prevention, complying with these technical standards is no longer optional—it's mandatory. By building a systematic management framework and monitoring regularly, you can optimize the impact these technical elements have on your app's ad monetization.
Wrapping Up
Ad monetization is a complex process that goes far beyond simply displaying ads and generating revenue. The three elements we looked at above are just as important as your surface-level performance metrics, and failing to manage them properly can stunt your app's growth in the long run.
For successful ad monetization, considering these elements holistically and building a systematic management framework is an absolute must. Technical aspects like mediation and ad network SDK version management, as well as app-ads.txt and SKAdNetwork IDs management, in particular, can be handled much more efficiently with the help of specialized tools. By automatically monitoring and managing these complex technical elements, DARO helps app developers focus on the essence of their product while still maximizing revenue.
Rather than obsessing over short-term results, leveraging the right tools to establish and execute a sustainable monetization strategy will be the foundation for your app's long-term success.
