There are many people around, some dont want to let you make some money, some are your competitors, some are your jealous friends. There are many many reasons with a person to get you ban from Adsense!!
Beware its the first sign ..Inform this matter immediately to adsense support team ..Otherwise most probably you will be banned
It is known as click bombing , email yourself to adsense team that you don't know how this happened and letting them know that someone did click bombing .
Why You are so worried,if you don't clicks on your own Ads.Adsense are smart enough to eliminate such fradulant Ads.Wait for some day,possibly the earning from such ads will be subtracted from particular earnings.You may also get e-mail if any thing gone wrong with your account.
I think this is probably an overly optimistic attitude. Adsense has no way to know if the invalid clicks were requested by the account owner or not. I would think that it's often in the best interest of Google's customers - the Adwords advertisers - to simply close the account where the problem clicks are occurring.
- May be someone tried to get ur account banned. better be at safer side. Dont encourage ur friends to click on ur ads.
I just wondering, does google give us some explanation or indicators which can be used by us to recognize the fraudulent/invalid clicks from the report?? and how to protect the ads from frauds?? doesn't google have 'the software' or 'scripts' to protect the ads from fraudulent clicks??? If someone has this scripts or software, please share with us to protect the ads...
Dont worry u just put some link group ads in ur site then ur page control decreases and then u will not get any problem my dear
Nonny advice on this was perfect. Tell them about it and refund the money if necessary. 18 clicks from 2 impressions might be technically possible but I don't see how...as when you click once you leave the page. And even if there is a way for that to happen legitimately its just not at all likely
