Imagine launching a re-engagement campaign with the confidence that you’re targeting existing, familiar users—an audience that’s supposed to be fraud-proof. It seems logical, doesn’t it? After all, why would fraudsters bother with users who are already in your database?
Unfortunately, this assumption couldn’t be more misleading. Re-engagement campaigns are not only impacted by fraud but are also increasingly targeted by sophisticated fraudulent techniques. Fraudsters see these campaigns as low-hanging fruit, exploiting weak attribution systems and leveraging the widespread myth that re-engagement is safer than acquisition of new customers.
Re-engagement campaigns are undeniably valuable. They help brands reconnect with dormant users, boost retention, and drive long-term growth. But failing to recognize the lurking threat of mobile ad fraud can turn these campaigns into a costly trap. In this article, we’ll uncover the hidden risks, types of digital ad fraud affecting re-engagement efforts, and how brands can protect themselves. It’s time to rethink what you know about re-engagement campaigns and ad fraud.
Common Misconceptions About Fraud in Re-Engagement Campaigns
- Belief that targeting existing users reduces the likelihood of fraud: Marketers often assume that fraud is less of a threat in re-engagement campaigns because the target audience consists of users already familiar with the brand.
- Perception that fraudulent activities are more prevalent in acquisition campaigns: While acquisition campaigns are a common target for fraud, re-engagement campaigns are equally at risk due to their high-value budgets and relaxed monitoring.
Types of Fraud in Re-Engagement Campaigns
-
Organic Poaching
Organic poaching occurs when fraudsters manipulate attribution systems to take credit for users who would have naturally re-engaged with the brand. These are genuine users who, due to their liking for the brand, were likely to return on their own. Fraudsters intercept their activity by inserting click be, before the user’s click making it look organic. This artificially inflates the campaign’s performance metrics, and the attribution platform marks this as an organic activity.
-
Acquisition Poaching
In acquisition poaching, fraudulent reengagement partners take advantage of attribution windows to falsely categorize newly acquired users as re-engaged ones. For instance, they may manipulate data to claim credit for a user who has just downloaded an app or made a first purchase, even though the individual was not part of the re-engagement audience. This not only wastes the re-engagement campaign budget but also blurs the distinction between acquisition and re-engagement efforts, leaving marketers with misleading insights.
-
Event Spoofing
Event spoofing involves fraudsters simulating user actions after a re-engagement campaign, such as fake logins, purchases, or app interactions. These fabricated events create the illusion that the campaign successfully drove meaningful engagement. However, these activities lack any real user intent or value, resulting in wasted ad spend and unreliable performance data. Event spoofing is particularly harmful because it often goes undetected until a deeper analysis reveals discrepancies between reported metrics and actual user behavior.
Impact of Fraud on Re-Engagement Campaigns
- Financial Losses and Wasted Ad Spend: Re-engagement campaigns are designed to maximize ROI by targeting users who are already familiar with the brand. However, when fraudsters interfere, ad budgets are wasted on fake actions that provide no real value. For example, event spoofing may create the illusion of reactivated users completing high-value actions, such as purchases or logins, while in reality, no such engagement has occurred. This not only drains resources but also diverts funds from genuine opportunities to re-engage actual users.
- Misleading Campaign Performance Data: Fraudulent activities in re-engagement campaigns can significantly distort performance metrics. Organic poaching and acquisition poaching, for instance, lead to inflated figures, making campaigns appear more successful than they truly are. When marketers rely on these skewed insights, they risk misallocating budgets, overestimating campaign effectiveness, and losing the ability to optimize future strategies effectively.
- Inefficiency in Targeting Actual Users: Fraud doesn’t just waste money; it also undermines the core objective of re-engagement campaigns—reconnecting with dormant users. Fraudulent actions skew targeting systems, making it harder to identify and reach genuine inactive users who could bring long-term value to the brand. Instead, marketers end up chasing fake interactions, missing out on real opportunities to reignite meaningful customer relationships.
Why You Need to Invest in an Ad Traffic Validation Solution: Real Cases
Case 1: Abnormal Click to App Open Rate
In normal case, most users get reattributed immediately after opening the app.
In the above case, about 60% of the clicks made by users on retargeting ads did not result in the app being opened immediately and it is done after 06th Hour, which clearly indicates large amount of click spamming to capture users opening the app organically.
Case 2: Repetitive Orders from Same GAID
Repetitive orders are getting placed from same GAID on the same time frame and same store also, all order is on Cash on Delivery. Refer below sample for the same, there are 212 such orders placed. This is a clear case of spoofed events.
Takeaway
Re-engagement campaigns are important for marketers to reengage their past users and be present in their minds. However, to increase the potential of these retargeting campaigns, marketers must also address the hidden risks of fraud to increase the potential of the campaign and reach maximum users.
