Fraudulent traffic is one of the biggest challenges in in-app advertising, threatening not only campaign performance but also ad spend and overall business integrity. From fake installs to click fraud, these deceptive practices can undermine efforts to reach a genuine audience, making fraud prevention a top priority for marketers.
This guide provides actionable strategies and insights to help detect, prevent, and combat fraudulent activities while ensuring campaigns attract high-quality, targeted traffic.
THE CHALLENGE OF MOBILE APP FRAUD

Distribution of fraud types on iOS
Common types of fraud:
- Install Hijacking: Malware intercepts app installation processes to misattribute conversions.
- Data Manipulation: Fraudsters alter metrics to falsify campaign performance.
- Click Flooding: Attackers send large volumes of fraudulent click reports to claim attribution.

Click flooding mechanics (also known click spamming)
To reduce the risk of fraud, it is essential to use trusted platforms like AppsFlyer or Adjust, which are designed to monitor and prevent fraudulent activities effectively.
Regular audits of traffic sources should also be conducted, combined with the implementation of filters to detect any suspicious patterns. Additionally, collaborating with premium advertising sources such as Moloco, IronSource, Unity, and Applovin helps ensure the delivery of traffic and minimizes the chances of encountering fraudulent behavior.

UNDERSTANDING YOUR TARGET AUDIENCE

Google Analytics: Demographic Overview
Once you’ve defined your audience, segmentation is essential. Group users by criteria such as:
- Country of residence
- Language
- Age
- Gender
- Income level
Accurate segmentation ensures your campaigns reach the right users, avoiding wasted budgets and maximizing efficiency. Targeting high-income users in specific regions often increases ROI, particularly in e-commerce campaigns. We provided a detailed explanation in “How to Improve ROI: Secrets of Optimizing Advertising Campaigns.”
LEVERAGING TARGETING STRATEGIES
Targeting is a cornerstone of effective in-app marketing. Proper setup ensures your ads resonate with the intended audience. Here are some best practices:
- Begin with Higher Bids: Place higher bids in the initial weeks of your campaign to attract more users and collect data. This allows the platform to optimize more effectively.
- Monitor and Adjust: Over time, gradually reduce bids to find an optimal balance between cost and performance.
While recent privacy regulations have introduced challenges, many targeting strategies remain effective. For example, Apple’s App Tracking Transparency (ATT) framework has impacted how advertisers track and target users. It’s essential, however, to be aware of potential traffic limitations in specific GEOs.
OPTIMIZING CREATIVE ASSETS
Well-designed creatives are responsible for up to 90% of success in in-app traffic campaigns. Here are some tips:
- Keep creatives simple, colorful, and engaging.
- Utilize AI tools to generate innovative ideas and designs.
- Use the most popular formats for in-app ads: 9×16 (vertical) and 16×9 (horizontal). Banners, especially the 320×50 format, are also widely used.
- Analyze competitor creatives using spy tools like Apptica to identify trends. Apptica provides a library of ad creatives by app category and custom-made taxonomy, enabling marketers to benchmark effectively.

RETARGETING: RE-ENGAGING POTENTIAL USERS
Retargeting is a powerful tool for re-engaging users who’ve interacted with your app but haven’t taken desired actions, such as making a purchase or completing a registration. It’s effective across various niches, including gaming and betting apps, and can significantly boost lifetime value (LTV).
To implement retargeting effectively:
- Identify users who have shown interest but haven’t converted.
- Design specific campaigns aimed at these users to encourage completion of the desired action.
AVOIDING AD BUDGET WASTAGE
Inefficient budget allocation is a common pitfall in in-app marketing. Avoid this by:
- Monitoring Campaigns: Media buyers should continuously oversee campaigns to ensure smooth optimization and data flow.
- Using Analytics Tools: Track key metrics such as CPM, CPI, conversion rates (CR), and ROI. Analyze raw data to uncover deeper insights.
- Optimizing Channels: Reallocate budgets from underperforming channels to those delivering better results. Duplicate successful campaigns to scale effectively.
- Building Blacklists and Whitelists: After gathering sufficient data, eliminate non-converting bundles and focus on high-performing ones.
