If you’re using AdWords or AdSense you must have heard about an emerging practice in the underworld of computing called “click fraud”. But what exactly is click fraud and how is it accomplished?

Well AdSense uses a payment mechanism that awards a certain amount of money to a publisher (someone who holds an AdSense banner on their page) every time a person clicks on the said banner. So click fraud is the attempt to have people clicking the ads just so that they can earn a greater income.

There are people setting up sites for the sole purpose of fraudulently generating revenue through Google’s AdSense program. These users achieve an incredible number of clicks through many methods, some complex and sophisticated and some rudimentary and simple.

One of the most complex is through the use of so called “hitbots”. These are automated programs who emulate clicking the links in AdSense banners (there are some that actually click the banners as well).

Google’s AdSense protection scheme is by no means perfect and nearly anyone can find the details of surmounting the protection mechanism, ironically just by doing a Google search.

Another, more rudimentary method is to hire a lot of people in a poor country to click the links on your site. This means these people will actually sit all day and just click links so you can earn a fortune. They come from very poor countries like India, and they’re prepared to do so for just $0.50 an hour.

Of course, there’s a problem with this mechanism. Once Google receives a large number of clicks from a single address, the address and the site that had the AdSense banner will be banned, and the illicit behavior might even get the fraudster sued.

To prevent this from happening, many people use a large number of proxy servers for the purpose of clicking. These are basically trojans, located on computers throughout the world (though mostly in the US). What’s even more daunting is that these clicks will appear to originate from an actual computer so such scams are really hard to detect.

And don’t think this happens only in isolated instances. There is a great deal of illegal activity in this domain.

In fact there’s so much that if search engine companies don’t increase their security with such programs as AdSense, such criminal behavior could become more become even more damaging.

Google has a very strict policy regarding click fraud, and it has sued those employing such techniques in the past. But while the search engine giant tries its best to minimize the risk of click fraud there’s certainly room for a lot of improvement.

It is estimated that more then 20% of the clicks that follow an AdSense link are just done in order to get money from the person paying for the ad. Some people believe the number of fraudulent clicks to be even twice as large.

There are a great deal more schemes involving click fraud, such as groups of AdSense publishers clicking each other’s links (which is referred to as “clicking rings”, or spamming people so that they click such links.

Despite Google still holding click fraud on a leash, the phenomenon is certainly raising concerns for the advertisers on AdWords, but despite this advertising with Google’s AdSense still remains more profitable for the advertiser, as opposed to traditional untargeted advertising schemes.

Low cost SEO is always evolving like any other approach in information technology. There are many methods that can very well land you on the top ten rankings of Google or on any other search engines. Some may cost a lot but there are methods that can give you the same results at a low price or you can even do on your own such as those mentioned above.

Google, being the undisputable leader in search engines from then until now, is placing a high importance on the quality and relevancy of its search engines. Most especially now that the company is public property. In order to keep the shareholders and users of its engines happy, the quality of the returned results are given extreme importance.

For this same reason, doing the wrong things in the Adsense and other forms of advertisements, whether intentionally or unintentionally, will result in a severe penalty, may get you banned and even have your account terminated. Nothing like a good action taken to keep wrongdoers from doing the same things over again.

So for those who are thinking of getting a career in Adsense, do not just think of the strategies you will be using to generate more earnings. Consider some things first before you actually get involved.

Hidden texts. Filling your advertisement page with texts to small to read, has the same color as the background and using css for the sole purpose of loading them with rich keywords content and copy will earn you a penalty award that is given to those who are hiding links.

Page cloaking. There is a common practice of using browser or bot sniffers to serve the bots of a different page other than the page your visitors will see. Loading a page with a bot that a human user will never see is a definite no-no. This is tricking them to click on something that you want but they may not want to go to.

Multiple submissions. Submitting multiple copies of your domain and pages is another thing to stay away from. For example, trying to submit a URL of an Adsense as two separate URLs is the same as inviting trouble and even termination. Likewise, this is a reason to avoid auto submitters for those who are receiving submissions. Better check first if your domain is submitted already an a certain search engine before you try to submit to it again. If you see it there, then move on. No point contemplating whether to try and submit there again.

Link farms. Be wary of who and what are you linking your Adsense to. The search engines know that you cannot control your links in. But you can certainly control what you link to. Link farming has always been a rotten apple in the eyes of search engines, especially Google. That is reason enough to try and avoid them. Having a link higher than 100 on a single page will classify you as a link farm so try and not to make them higher than that.

Page rank for sale. If you have been online for quite some time, you will notice that there are some sites selling their PR links or trading them with other sites. If you are doing this, expect a ban anytime in the future. It is okay to sell ads or gain the link. But doing it on direct advertisement of your page rank is a way to get on search engines bad side.

Doorways. This is similar to cloaking pages. The common practice of a page loaded with choice keyword ads aimed at redirecting visitors to another user-friendly page is a big issue among search engines. There are many seo firms offering this kind of services. Now that you know what they actually are, try to avoid them at all costs.

Multiple domains having the same content. In case you are not aware of it, search engines look at domains IPs, registry dates and many others. Having multiple domains having the same exact content is not something you can hide from them. The same goes with content multiplied many times on separate pages, sub domains and forwarding multiple domains to the same content.

Many of the above techniques apply to most search engines and is not entirely for Google only. By having a mind set that you are building your Adsense together with your pages for the human users and not for bots, you can be assured of the great things for your ads and sites.

Not to mention avoiding the wrath of the search engines and getting your Adsense and site account terminated altogether.
