IAA Game Attribution Guide｜How to Track Users in Ad-Monetized Mobile Games

IAA (In-App Advertising) games are a thriving genre in the mobile gaming world. Developers earn revenue by showing ads—such as rewarded videos or interstitials—while letting users enjoy the game for free. Most IAA games acquire users via paid ads, but there’s one key to profitability: knowing exactly where those users come from. That’s where attribution comes in.

What Is Attribution?

Attribution is the process of connecting a user’s in-app actions—like installs or conversions—to previous interactions with ads.
In simple terms, it answers the question: “Which ad channel brought this user in?”

Without attribution, developers can’t evaluate the performance of their marketing efforts or optimize ad budgets effectively.

Why Is Attribution So Important for IAA Games?

For IAA games, attribution plays a critical role because:

• Revenue depends on user scale: Since income comes from ad impressions, you must understand user LTV (Lifetime Value) to scale profitably.

• Short acquisition cycles: Ad campaigns are often optimized daily. Fast feedback is necessary to make smart decisions.

• Multiple ad networks: Channels like Google Ads, Meta, Unity Ads, and Mintegral need to be tracked in one unified view.

Common Attribution Methods

Here are the most common attribution methods used today:

1. Last-Click Attribution
   The default model. If a user clicks an ad and installs, the click is credited. Simple and easy to implement, but it may overlook earlier engagements.

2. View-Through Attribution
   Sometimes, just seeing an ad is enough. If a user installs after a view (without a click), some platforms still credit the ad. Controversial, but relevant for brand-focused campaigns.

3. Multi-Touch Attribution (MTA)
   This model assigns credit to multiple touchpoints based on weighted influence. Complex to implement, usually used by mature teams with large budgets.

4. SKAdNetwork (for iOS)
   On iOS, Apple enforces privacy via SKAN. Though limited in granularity, it's the go-to for measuring post-iOS 14 attribution and can still support IAA optimization via modeling.

Who Handles Attribution? The Role of MMPs

Attribution is typically handled by an MMP (Mobile Measurement Partner). These tools offer unbiased attribution across various ad networks.

Top MMPs include Adjust, Appsflyer, Singular, and Tenjin. Chinese developers can also use SolarEngine—a third-party solution that supports global attribution and analytics.

SolarEngine provides attribution and behavior analytics for IAA games, helping developers evaluate channel performance and optimize monetization. It offers cross-platform SDKs and is easy to integrate.

What Attribution Metrics Should IAA Developers Track?

If you’re new to attribution, focus on these essential KPIs:

• Install Source Breakdown: Which channels are driving the most installs?

• ROI / LTV: Which channels bring high-value users?

• User Retention: Are users sticking around or leaving after the first ad?

• Ad Impressions per User: How often are users seeing ads?

These insights help improve both user acquisition strategies and monetization outcomes.

Summary: Attribution Is the Starting Point for IAA Game Growth

Attribution isn’t just a technical setup—it’s the foundation for smart scaling in IAA games. It affects every aspect of your marketing, monetization, and overall business success.

SolarEngine helps IAA developers close the loop from acquisition to monetization, offering lightweight attribution and in-depth behavioral analysis across markets.
