I have in yesterday report one channel with only 5 page impressions and 24 clicks also clicks are not paid. How ad can be clicked if page is not shown? Is this some kind of click attack, anyone else have seen this?
1 click doesn't necesarilly come from 1 impressions. If your visitor push (or click?) the back button without reloading the page and click on google ads on your site.. there it is, 1 impressions generate more than 1 click. In your case, it could be due to click attack, or it is just google hasn't updated earnings, clicks and impressions. The best is to inspect where the click(s) come from and inform google immediately
