How Google Detects AdSense Invalid Clicks
Still thinking to cheat AdSense? Stop that. It will never bring you anywhere. You might pull it off with smaller ads network, but definitely not with Google. Here are some detection methods they might use. At the very least, they have the resources to do so.
IP Address
If the AdSense click is originated from the same IP Address as the one used for accessing your AdSense account, your account is flagged.
Cookies
Most home users do not use static IP Address for Internet connection. In most cases just disconnect and reconnect will give you a new IP Address. But don’t forget, Google has set cookies on your computer.
Other Google Services
Thinking that you are safe just because you do not access your AdSense account? Think again. This time, consider these: GMail, Google Earth, Google Calendar, Google Search, Google Toolbar, Google Talk, Google Sitemap, Google Desktop, Blogger, and so on, and so on. With the wide range of services they provide, Google can trace the originator of most (or probably almost all) clicks.
Click Pattern 1
Oh, why this computer / IP address / person is so trigger-click-happy on this particular website but never click on the ads on other sites?
Click Pattern 2
And why is it that people accessing these sites direct (type-in URL or from bookmark) tend to be very active ad-clickers compared with those referred from search engine or other sites?
Click Pattern 3
And why the ad-clickers like to hit and run, compared with non ad-clickers that surf a few pages before leaving?
Click-Through-Rate (CTR)
Your CTR may range from 0.5% to 10%, but if it exceeds a certain point (probably around 10%), you are flagged.
Geo-Location
Used Urchin (Google Analytics) before? Then you should know that Google can trace traffics origin down to the small town. Different IP doesn’t mean much. Unless you site is really targetted to one small geo-point, a high number of clicks from nearby location will get you banned quickly.
Hardware address?
MAC address of the LAN card, modem, and router works almost like a fingerprint. I’m not sure if Google can track this, but probably they do. They have rocket scientist, remember?
Advertisers conversion rate
Ad click is one thing. But does it bring value to the advertisers? If none of the clicks on your site translate to conversion to the advertiser, you are in trouble. First the Smart-Pricing hits, then your AdSense account disabled.
Search Engine Ranking
Your website is not indexed on any search engine, not linked by any prominent website, but get consistently high traffic? That sounds like something is in play. Regardless of whether it is an adware-embedded software, spam, trojan clickbot, or intentionally installed click-exchange network, it doesn’t sound right.
Webpage design
How about the “click here” or “support us”? Google has the best search engine in the world. Is it really that hard to find those words?
Combo
Each of these detection methods might seem rather weak. But combine them together, and not many click-fraud can pass-through these filters. Even the smartest clickbot will have a hard time.
In short, it is almost impossible to cheat AdSense in the long term. Instead of spending time, money, and effort trying to outsmart Google, try these tips to improve your AdSense earning.
Disclaimer : I’m not working for Google nor in anyway know anyone inside Google. Google might or might not use these methods to detect click-fraud. I’d believe that they have much better detection mechanism.

Hi, I lost my adsence account for too many clicks, well I just did it to see how the clicking works, but by that time adsence account was cancelled by them. since then I am trying to again get adsence by appliying in different names but same IP address. But still no luck, all my attepts were in vain as it was rejected . Once u get rejected do they ever approve a account, atleast after some time?
No, they won’t approve it anymore.
Edit: They might approve it for awhile, then terminate the account again once find out that it belongs to you.
thanks for sharing this bro, the cheaters now must beware in cheating adsense
Thanks. Nice site, bro…
thats bad but im going to keep trying until i get free clicks …google is big they are not going to wasted their time tracking small websites anyways.
Unfortunately for you, and fortunately to the advertisers, Google pay a lot of attention to small publishers. In fact, if you run large sites, Google can probably ignore a couple of inadvertent clicks, but not if you run small sites.
Thanks for this useful post . i am new to this adsense but i dont know how to attract users to click on my ads
It is a nice summery of counterfeit techniques. But I am surprised how people still manage to steal way from Google?
I have been reading through a lot of articles about click fraud. You address the issues at hand well. Take for instance some you left out, you might find useful guys. http://www.associatedcontent.com/article/5964124/how_to_earn_online_income_with_google.html?cat=35
I cannot believe people still try it on… just read the Adsense TOS, that is why it is there, so you can avoid the pitfalls.
Nobody can steal from Google anymore, just forget it and concentrate on making your site successful – Google give you the tools for free in many respects, they don’t have to do this. They could just roll out the program to large companies and still make a fortune… you are lucky to have a large company such as Google working with you for next to nothing… use it, obey the rules and you will eventually make money.
It is not going to happen in a month unless you are truly a niche or very very lucky!
Actually, back in 2008 I’ve been in good situation receiving adsense income but when I got caught on fraud clicks, yeah, I got banned definitely. After lesson learned i tried registering another account but all of my attempts are failed. I said to myself I will try and try until I get one and after that I will behave and take care of that adsense account. I will never click it myself. And you know what after 2 years, I got approved.
Look like Google pretty smart , the more you fraud click, then next time Google may more easy to analysis fraud click from your site. That why more blogger would like to look for other adsense and merchant would like to look for Google Adsense.
Ya a lot of people do try to cheat, I am sure.
However, Google will invalidate anyone who clicks and didn’t like what they see. Half my clicks are not paid, and there is no way to contact Google that I know. They have a wall up so nobody can ask questions.
I don’t cheat and never have – I think some people click on an add and quickly determine their not interested and Google thinks this is a false click – they really don’t care if it was real.
People need to stop thinking Asense is just easy free money. Money is never easy to get. In order to get money it requires work. If you dont have traffic on your site, dont get adsense. Work to get traffic.
Well! i agree with you but maybe you don’t know every thing google do track fraud.But here in our country its like a business.I have meet people with 100 adsence accounts.There job is adsence they earn thousands of money on monthly basis doing fraud with google i think every thing is possible but if we have the right knowledge and right tools for doing this even my account was disable and I was not able to get another one when i tell those guys they give me a new account just in houre and also told me the trick how to make new one on same ip addres and how google will approve that in just hour.So Google is noting
hi there thnx for ur input
how can we put our sites to visitors
what is ur advice
we see people making so much money
how r they doing that
thnx again
It is both unethical and illegal to click your own ads.
You ain’t kidding about them. If they have any idea that you are linked to your website clicking on ads they will black list your ip and your websites. be very careful. I have noticed if you click from different wifis they give you credit.
@Jimerston
LOL
why google cares abbout 300 bucks a month shame on them.
I got a computer and a laptop, I made my adsense Account on the computer but I logged once on the laptop my question is can I click on my Ads on the laptop?
No, you cannot click on your ads, anywhere.
I think sometimes that if people worked as hard to be legitimate as they do to cheat, they would be quite successful.
I Know How To Get Adsense Aprove in 24 hours.Also How To Click Your Owns Ads And Get Credit All Works With Google Apps And Browsers.I Don’t Know If Thats Legal Since All Programs Are From Google
Be my guess and try it yourself. Just don’t blame anyone when you get banned.
Sobering assessment of the adsense pehonomenon…….
Although, some of the points are truly fantastic but what is our fault when user clicks on the ad and leaves.
It’s not your fault, really. But why would so many people be interested to click but noone is interested enough to browse a minute or two?
Google is god.
I think I’m very lucky because I clicked my ads two times in coincidence (on the same day) but I didn’t get kicked. Probably because it was my first day, and it was not my intention to click on it.
