Navigating Mobile Game User Acquisition: Strategies to Avoid Fraud and Maximize ROAS


With millions of active players across the globe, it’s no surprise that user acquisition has become a top priority for mobile game developers. However, with the rise of fraud in user acquisition, it has become increasingly difficult to navigate the mobile gaming industry. In this blog post, we will explore the issue of fraud in user acquisition and provide strategies to avoid fraud and maximize ROAS.

How does fraud happen in mobile gaming?

User acquisition fraud is any fraudulent activity that artificially inflates the number of installs, clicks, or views on a mobile game. Several common types of fraud in user acquisition include fake installs, click spamming, SDK spoofing, and bots and farms. 

  • Fake installs occur when a user is paid to download and install a mobile game without any intention of playing it. 
  • Click spamming is when a user clicks on an ad multiple times to inflate the click-through rate artificially. 
  • SDK spoofing is when fraudsters impersonate legitimate SDKs to steal attribution data. 
  • Bots and farms are automated programs or groups of people that artificially simulate user behavior to inflate metrics.

The impact of fraud on user acquisition and the gaming industry as a whole is significant. Fraudulent activity can lead to wasted ad spend, reduced engagement, and a negative impact on the user experience. Furthermore, it can harm the reputation of the mobile game and the developer, decreasing user acquisition and revenue.

Beware of these signs!

It is important to recognize the signs of fraudulent activity to avoid fraud in user acquisition. One way to identify fraudulent installs is to look for patterns of behavior that deviate from typical user behavior. For example, if many installs come from the same IP address or device, it may be a sign of fraud. 

Multiple installs from the same IP address or device: If you notice a high volume of installs originating from the same IP address or device, it could indicate fraudulent activity. Legitimate users typically have unique IP addresses and use various devices, whereas fraudsters may attempt to generate multiple installations from a single source. Keep an eye out for disproportionate installs coming from a single IP address or device.

Click spamming: Analyzing click-through rates can help identify abnormal spikes that may be signs of click spamming. Observing a sudden and significant increase in clicks within a short period could indicate fraudulent activity. Fraudsters may employ techniques to artificially inflate click numbers, making it seem like there is a high level of user interest when, in reality, the clicks are generated through fraudulent means.

SDK spoofing: Monitoring attribution data can help uncover discrepancies that point to SDK spoofing. You should ook for inconsistencies between the attributed installs or actions and the expected distribution. If the data indicates unrealistic user behavior or if there are discrepancies between the reported data and actual user interactions, it may indicate that the attribution data has been manipulated.

Bot activity and farms: Detecting bot activity and farms involves analyzing user behavior for patterns that deviate from normal user behavior. Signs such as excessive app usage within a short period, consistent patterns of interaction, or similar behavior across multiple user accounts are what you don’t want to see. Bots often exhibit predictable and repetitive actions, lacking the natural variations observed in genuine users.

Also, here’re some metrics to look out for:

Install conversion rate

  • Observe the average conversion rates of your competitors or similar brands.


  • If CTIT shows hours or days, this might indicate that you are dealing with ad fraud. The expected turnaround time for most ads is seconds or a few minutes.

Funnel-down event

  • If your app has funnel-down events such as sign-up or creating an account, and they are completed before the needed interaction happened, this might indicate fraud.

Here’re Some Best Practices to Avoid UA Fraud

Tips for Verifying Genuine Installs

Analyze IP Addresses and Devices:

  • Look for various IP addresses and devices associated with the installs.
  • Be cautious if a significant number of installs originate from the same IP address or device, as it may indicate fraudulent activity.

Monitor Install Patterns:

  • Examine the timing and frequency of installs to identify any suspicious patterns.
  • Large spikes in installations within a short period may indicate fraudulent behavior.

Validate User Engagement:

  • Assess the level of user engagement, such as app usage, actions taken, or purchases made.
  • Genuine users typically exhibit varied and meaningful engagement, while fraudulent installations may lack real user interactions.

Strategies to Detect and Prevent Click Spamming:

  • Track Click-Through Rates (CTRs):
    • Regularly monitor CTRs to establish baseline metrics.
    • Look for sudden and significant spikes in CTRs, as it may indicate click spamming attempts.
  • Set Realistic Expectations:
    • Compare CTRs with industry benchmarks and historical data.
    • Unusually high CTRs that deviate from expectations should be thoroughly investigated.
  • Implement Fraud Detection Tools:
    • Utilize specialized fraud detection tools and services to identify and filter out fraudulent clicks.
    • These tools often employ advanced algorithms and machine learning techniques to detect patterns of click spamming.

Measures to Counter SDK Spoofing:

  • Monitor Attribution Data:
    • Regularly analyze attribution data to identify any inconsistencies or discrepancies.
    • Look for discrepancies between reported installs or actions and the expected distribution.
  • Validate User Behavior:
    • Compare the attributed installs or actions with typical user behavior.
    • Unrealistic user behavior or unexpected patterns may indicate SDK spoofing attempts.
  • Establish Secure Attribution Frameworks:
    • Implement secure attribution frameworks that leverage encryption and authentication mechanisms.
    • This helps prevent unauthorized modifications or manipulations of attribution data.

Techniques to Identify and Block Bot Activity and Farms:

  • Analyze User Behavior:
    • Study user engagement patterns to identify behaviors that deviate from normal user activity.
    • Look for excessive app usage within a short period, repetitive actions, or similar behavior across multiple user accounts.
  • Employ CAPTCHAs and Human Verification:
    • Implement CAPTCHAs and other human verification mechanisms during critical touchpoints.
    • These measures can help distinguish human users from bots or automated scripts.
  • Utilize Machine Learning and AI:
    • Leverage machine learning and AI algorithms to detect and classify bot activity.
    • Train models to identify bot signatures, anomalous behavior, and patterns associated with bot farms.

Tools and Technologies to Combat User Acquisition Fraud

What are some anti-fraud tools for user acquisition?

To identify and block fraudulent installation attempts, fraud detection software like Adjust, Kochava, or Singular, utilize sophisticated algorithms and machine learning. These tools analyze a wide array of parameters, such as IP addresses, device fingerprints, click patterns, and user behavior, to flag suspicious activity and prevent fraudulent installs.

Distributing analytics platforms like AppsFlyer, Branch, or Adjust can improve user acquisition campaigns. As users click on ads to install apps, they track their journey, helping to verify genuine installs. User acquisition managers can identify discrepancies and anomalies in attribution data with these tools, enabling them to validate attribution data and analyze user engagement.

DoubleVerify, MOAT, and IAS (Integral Ad Science) are a few examples of ad verification tools that play a crucial role in ensuring the authenticity of ad impressions and user interactions. The tools use sophisticated algorithms to detect and remove non-human traffic, such as bots or farms, from ad campaigns. In order to reduce the risk of ad fraud, ad verification tools monitor viewability and click-through rates.
