What Is Click Injection?
Click injection is another type of ad fraud that follows much of the same patterns of its brute-force brother. The main point of difference is where and when these clicks are sent. These clicks are not sent before the install (like click spamming) rather immediately after the genuine install begins.
This aim is for the MMP to see the fraudulent click last (as the fraudulent click is sent after the genuine install has begun) and therefore, mistakenly misattribute the install to the fraudulent click instead.
