Was it a Search or a Display Campaign for Google? I could understand that adsense webmasters used clickfarms. However finding out that google is using clickfarms for Search campaigns would be uncovering the greatest scam of the Internet.
I was optimizing for best behavior - so, in the case of Google - Google Search Network only, no network partners. I also moved Mobile devices to -100% so I don't bid in that space. So, desktop & tablet only.
Automating clicks on competitors ads might be beneficial for companies who are competing on the same keywords.
This could be of course just ordinary user behavior. When searching something, I'm opening tens of different pages. Probably I scroll quite quickly through most of them. Just made some quick tests and I think on mobile phone I also act as described, so just flick to the end of the page glancing stuff on my way.
Interestingly the behavior is similar to what I have observed with Mouseflow recordings for organic Google+ and Facebook posts. The page is opened, the mouse never moves and the 'user' scrolls a couple of times. I wonder if these records could just be the regular reviews that Google and Facebook do; their visits do not show up on Google Analytics but Mouseflow is able to take recordings.
Isn't that how legitimate mobile or even laptop trackpad users look ? If I don't intend to click anywhere, the "mouse" cursor never moves - the page loads, I scroll, and go back by keyboard.
With a mouse, you get slight movement even while scrolling or pressing buttons, but with a trackpad or on a mobile device you don't, there's "mouse movement" even if you explicitly do some aiming before a click.
