So recently maybe starting like 2 weeks ago I started getting a whole bunch of clicks and a low cpc. I thought nothing of it at first but when I looked at the type of ads that were being clicked I saw that I had a whole bunch of invalid clicks on image, rich media, animated and flash ads. And whenever I set it to text only the problem of a high number of invalid clicks disappears. I tried looking it up on google and people had similar problems but no definite solution.
You can contact google adsense about this problem and tell them about this issue. Ask them to block ads on specific ips where u r getting invalid clicks
I think your ad might be too much effective, people are going to click any ad for the two reasons, one is if it is attractive and second one is whoever wants the real services if your ad is related to their expectation then they click, now you re getting invalid clicks means your image is too attractive, so its better to do some modifications.
You urgently need to contact Google an tell them IP address from where you are getting this clicks because if you don't complain then google will ban you so be catious!!
I dont think its coming from a person since i only get it for image ads. MAybe from a bot that triggers invalid clicks on image ads. I remember reading on google adsense forums that some people had trouble with Amazon bots clicking their image ads but idk to check if its happening to me. Anyways i'm only showing text ads atm and not having invalids. I only posted this b/c i hate text only ads. I enabled one of the text ads to text/image and didnt have the problem today, ill see how it goes tom
