After I decied to just drop mobile entirely, where 99% of the clicks were fraudulent (and indeed cheap, something like 1 or 2 cents was common), the campaigns in question had huge drops in total cost per month, one of them was sadly, literally 100%, meaning every single click on some months was fraudulent (that campaign is still active, it gets like 2, 3 clicks per month) Mind you, the campaigns with most fraudulent clicks, were the ones setup by google employees, they regularly insist in calling me to "help", explain new features and whatnot, every single time I setup a campaign following step by step their employee, the result was ridiculous amounts of fraud. The campaigns that bring me most of my real world income are the ones where I ignore what google wants for most part and do it my way.
