CPA fraud (cost per action fraud) is a type of click fraud where fraudulent actors manipulate the mobile attribution process to earn commissions for actions that real users did not actually complete. This fraud can take many forms, including the use of bots, click injection, and device spoofing. In some cases, fraudsters may use these methods to artificially inflate the app install or in-app event numbers to earn more commissions from advertisers.
Click injection is a type of click fraud that occurs when a third-party app injects fake clicks on an advertiser's ads. This can happen in various ways, such as through the use of malware or through the use of a click injection SDK. The goal of click injection is to inflate the number of clicks on an ad and generate fraudulent revenue for the mobile app. The consequence for the advertiser is that they are charged for fake clicks that never happened, and this can lead to a waste of the advertising budget.
CPA fraud, on the other hand, is a type of fraud that occurs when a publisher is paid for fraudulent actions. The consequence for the advertiser is that they are paying for fake conversions, not just ad clicks.
In summary, click injection is a fraud that inflates the number of clicks on an ad, while CPA fraud is a type of online advertising fraud that occurs when a publisher is paid for fraudulent actions taken on an advertiser's app. Both types of fraud can lead to a waste of advertising budget and cause significant financial losses for the advertiser.
One of the most common methods of CPA fraud is through the use of bot traffic. Fraudsters will use a network of bots to simulate real user activity and generate fraudulent conversions. For example, a bot might simulate a user clicking on an ad, completing a form, or making a purchase. The publisher will then be paid for the fraudulent action, even though it was never taken by a real person.
