Only partially, unfortunately. One of the things sophisticated fraudsters do is replay actual user sessions to build fake profiles. That is, they record scrolls and clicks on compromised devices, and have other users build similar profiles by following similar sessions on other compromised devices. This includes browsing FB and interacting with AdWords of course, and screws up PPV, PPC, and PPI metrics all over. On top of building more valuable fake user profiles for the latter two purposes, doing this allows to bypass click-density based ad fraud detection. See this article for an example of what you see when you can sometimes observe using the latter when detecting the less sophisticated fraudsters: http://adage.com/article/digital/inside-google-s-secret-war-... As the latter article implies, Google's team is pretty sophisticated at detecting fraud. But even then, seeing things like this suggests there are edge cases they'd like to see go away or that are hard to detect: https://news.ycombinator.com/item?id=13327228 |
