Click fraud occurs in pay per click online advertising when a person, automated script, or computer program imitates a legitimate user of a web browser clicking on an ad, for the purpose of generating an improper charge per click. Click fraud is the subject of some controversy and increasing litigation due to the advertising networks being a key beneficiary of the fraud whether they like it or not.
Use of a computer to commit this type of internet fraud is a felony in many jurisdictions, for example as covered by Penal code 502 in California and the Computer Misuse Act 1990 in the United Kingdom. There have been arrests relating to click fraud with regard to malicious clicking in order to deplete a competitor's advertising budget.
In 2004, a California man created a software program that he claimed could let spammers defraud Google out of millions of dollars in fraudulent clicks. Authorities said he was arrested while trying to blackmail Google for $150,000 to hand over the program. - Wikipedia
Types of Click Fraud
1. Basic clicker cheat - This is a noob. This guy knows almost nothing about web technology or network architecture. He clicks on his ads every time he has chance. It can be a few clicks to hundreds of clicks daily. Most likely he doesn't even read the AdSense Program Policies and Terms and Conditions.
2. Proxy clicker cheat - She knows a thing or two about cookies and IP address. Or she doesn't know, but somehow guessed that if she use the things called anonymizer, Google will not be able to trace her, because her identity is hidden.
3. Multiple computer clicker cheat - He knows that somehow Google will detect if the clicks are originated from his own computer. So he will try to even out origin of the clicks. He will recruit his friends, family members, relatives, neighbors, his cats, and his dogs on single mission: to click on the ads. He will also click on the AdSense ads when he is using the library computers, or his office workstation.
4. Software clicker cheat Graduate to the next step is buyers of clickbots / click-bots. These are specialized robot software to click on AdSense ads. It will browse around your websites, clicking on the ads every few minutes. The more advanced ones will cloak the IP address too, so the website seems to be very popular worldwide. To cover the track, this clickbots will browse around the advertisers sites too while continuing its "click quest".
5. Paid-clickers cheat - If you don't like automated things, there is always other option for you. Just pay $50 dollars a month to the professional AdSense clickers. These are groups of highly specialized Internet surfers with office in the dark rooms in street corners of India, Pakistan, and China, helping AdSense account owner to earn good amounts of money - before the AdSense account is disabled, that is. They will browse around your websites, clicking on the ads every few minutes. Because they use human eyes, they know which ads worth more. And to be more convincing they can click a link or two, or sign up free offers / newsletters on the advertiser sites.
6. Click-rings cheat - Network is power. So says many business gurus. Instead of taking things into their own hands, these people realize that they can join hands with those with similar goals and distribute AdSense clicks among themselves, the so called AdSense click-rings. Joining this click-ring network means that your website address will be made known to members, who will regularly browse the website and click on your AdSense ads. In exchange, you will also browse other members' sites and click on their AdSense ads. The medium used varies. Some click-ring groups use mail-list for communications. Some are using bulletin boards/forum, Yahoo groups, or Usenet. IRC is another popular way. Slightly more complicated is specialized AdSense exchange software for collecting members website address and displaying others' websites for clicking.
7. Other medium cheat - I have tens of thousands email address on my newsletter subscriber list. If I include AdSense ads on my newsletters, with 5% CTR, I can get a thousand clicks per one email. Not bad. Or I can pay someone to write some useful/nice/funny/cute toolbars or firefox extensions or screensavers that people can download and use for free, and display my AdSense ads there.
8. Visitor cheat - Simply putting "Visit our sponsors" or "Check out the ads above" on your website is cheating. This might not be very clear-cut cheat to some. But Google AdSense program policies has stated clearly, the only text allowed are "Advertisements" or "Sponsored List"
9. Spam cheat - This is the highest level all click-frauds, the Maestro of Fraudsters. She spams millions of emails regularly, offering to "satisfy your inner needs if you can help me check on the links on my website". Of course, email is not the only way. What IRC and instant messaging (IM) are for, after all. She will look for unsuspecting victims, offering something too-good-to-be-true "if only they will visit the website and click on the links".
10. Click-through-rate cheat - Whichever method(s) above used, there is one limiting condition: the CTR(click-though-rate). Any CTR that exceeds certain percentage (probably around 10%) will raise red flag in Google AdSense back room. To lower the CTR, the professional cheaters will create some pages on the same domain that attracts very high traffic. Some interesting freebies will sure do the tricks. AdSense code is pasted there, thus creating a very high page impressions. Whether or not the the ads are clicked does not matter anyway, because they are targeting low paying keyword that does not have much competition. The fake clicks are, of course, on where the big money is, the low traffic pages stuffed with high-paying keywords.
Why You Shouldn't Cheat AdSense
If you applied for AdSense account with intention to cheat and earn fast bucks, I hope by now you have understood that you shouldn't.
Why? You say. Google is so rich, losing some pennies won't hurt.
Well. Probably. But when I say you shouldn't, trust me. You really shouldn't. These are just some reasons...
1. You can't cheat Google
Every once in while, someone will comes out with ingenious idea of how to get more money from AdSense in less than honorable ways. He will announce to the whole world, posting in every forum and tell people how smart he is. His idea is always untraceable by Google, it is always original, and it always gives easy money.
What he doesn't know is, few months after that, he will get caught by Google, always. And his AdSense account will be disabled. Always. And he is banned from ever applying for AdSense account again. Always.
Google is a giant, with 2005 revenue of almost US$ 10 billions, and profits of more than US$ 1 billion. A large chunk of this comes from Adwords / AdSense advertisements.
More click fraud means less trust, less advertisers and less money, to the extent that if unsolved it will bring collapse to pay-per-click advertisement business. Now. Do you think Google will let you jeopardize their billion dollar business model?
They have money and ability to bring together many of the the smartest and brightest engineers and scientists on earth, has been doing that and will continue to do so. How smart do you think you are that you can outsmart collaborative effort of the brightest brains?
You might be able to pull through for two or three months, but eventually the fraud detection algorithm will catch up and you are caught. And you get banned from Google AdSense, among other things.
2. Cheating is stealing
No matter how you want to justify, face it, cheating is stealing. You are not only stealing from Google, but also from Adwords publishers. Majority of these are are not big companies, but small webmasters depending on Internet to make a living.
Moreover, even if your morality (or lack thereof) permits stealing from your own fellow, bear in mind that stealing is illegal. Regardless of whether it is done offline or online, a crime is a crime. You might get jailed for that.
In fact, Google has started to bring AdSense fraudsters to court a few months ago. Some were jailed, and some others were fined heavily.
It is just too easy to earn more, legally
Let's say you managed to cheat AdSense undetected. You don't use clickbot or proxy or click-ring or paid clickers. You managed to somehow get the clicks from distributed IP. You don't use pop-ups, spyware, adware. You are careful that your CTR does not exceed 10%. Still, your earning is limited. There is a cap you can't cross, else you will invite unwanted attention to your account.
With so much effort to cover your traces, actually you will get better result if you concentrate your effort to improve the website.
Write more content, submit articles, improve on your search engine optimisation, improve adsense placement, and you can get the same earning or even more. Sure it will take some time, but this is legitimate.
Some of the methods which Google uses to determine and detect cheating Still thinking to cheat AdSense? Stop that. It will never get 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.
