Hi everyone! I found an interesting article How to prevent stealing your income by an ad network covering the problem of how ad networks cheat webmasters to increase their income. The article says that some ad networks like to carry out additional manipulations on websites like aggressive advertising settings, using multi-format or even intentionally shaving part of the traffic that comes from one IP address to increase CPM. The worst thing is that webmasters have no idea about real settings and ad networks use websites for their own gain. Has anyone had a negative experience when ad networks cheated you? And how did you detect cheating ad network?
