How Google Ad Sense calculates cheated clicks:
First is the IP address and geographical location. If you click on the advertisement will have to go with an IP address from which you go at least once in your account – you are a cheater, immediately and irrevocably!
Secondly. More advanced users use dynamic IP! Yes, disconnect from the Internet, and join again, you change your IP, but Google for each click computer places on your computer Cookies.
Third – your modem or router, or LAN-card with your number (ID, Hardware address, Mac-address) – this is for Google to find how criminalists – fingerprints at the crime scene.
In the fourth “underlined” click. You do not need to study philosophy in order to understand what should be the visitor of your site or blog that clicks on an advertisement as soon as looked at the site without reading it. Or click on the advertisement, and soon came back. And in general, why “clicker” has got to your blog or website for direct contact, rather than on the search query or links from another site?
The fifth – a clear violation of Google Ad Sense. “Make money by clicking on the ads” – even if you do not post this text directly sooner or later Google will find it. Again ban again no money.
Sixth – your top resource. If your blog or website is new and there are no links on the Internet, your site is not to issue a search request, and the number of visitors is very little – it is very suspicious.
Seven – Spies around you – Gmail, Google Toolbar, Blogger, Google Talk, Google Sitemap, Google Desktop, Google Earth, Google Calendar, Google Search, Feed burner, and many others…
If you read everything carefully, you probably have noticed that you can be banned even if you are crystal clear – you do not do fake click, but by working with your Gmail mailbox at their workplace (or in Internet cafes). Be careful!
Good luck, and the big check from Google and if you are doing your business fair then probably you won’t get banned by Google!
