Understanding Click Fraud in AdSense: How It's Done and How Google is Fighting Back

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.

There are some means of protection against such schemes and all advertisers should be savvy enough to employ them. Many advertisers choose to avoid the content network all together for fear of click fraud.

The Success of Google AdSense: How It Benefits Advertisers, Publishers, and Visitors

 When Google's AdSense appeared, there were a lot of people who doubted Google's idea would be marketable and actually generate any profits. Yet as we stand here today it's probably the most well known pay per click venture in the world.

Yes, all those nay sayers ended up eating their own words in the end. And that is because the folks at Google never go and do something without assessing whether or not it will be profitable, or exactly how profitable it is.

But of course, as you might very well know, AdSense isn't just profitable for Google. It's also profitable for the people who advertise via AdWords and very profitable for publishers who use it to make earnings which are sometimes just enormous.

So one must ask himself why this is such a good deal for everybody. And the question in itself is very justified because you hardly ever come across something that's profitable for everyone in the chain. So why would AdSense be any different.

Well, AdSense is where it stands today, giving benefits for everybody in the game because it exploits a gap in the Internet's advertising model.

You see, the Internet is a very interactive environment, and its interactions come from the people who are browsing. They choose whether or not to follow a certain link and the term "navigating" is probably the most precise one at describing this situation.

So AdSense is great because it links together buyers and sellers. Yes, you have to hand it out to Google for a brilliant idea. They know there are people out there that want to buy stuff and people who want to sell them what they're interested in. And Google AdSense helps members of the two categories find each other.

It works for the visitors, because the model is very transparent. You don't see a huge graphic banner which tries to lure you into buying something. You just see a few words. And if you like what you see you can just click it. It works because visitors don't have that feeling of someone trying to lure them into spending money. Ironically, however, they're wrong.

It works for the AdWords advertisers because their ads go everywhere. Not only will they find themselves listed in Google's search which gets gazillions of hits per day, up front without working as much for SEO and waiting so much.

Their ads can reach any website that deals with anything similar to what they're trying to sell. Now you must realize they could never pull of such great advertising by themselves. And that brings us to the thing that makes Google's AdSense a publisher's best friend.

It comes from the fact that the ads are contextual, that they somehow related to the keywords you deal with on your page. Because people or on your site, which deals with a certain topic, you already know they're interested in that topic. 

But, hey, wait a minute, Google knows some companies which want to sell your visitors something related to their topic. Google wants your visitors, you want Google's advertisers and the visitors just want to buy stuff. And that is the essence of what makes AdSense a great deal for everybody.

This is by far the most profitable hook-up deal you're ever going to see anywhere on the Internet.

So you have to appreciate Google for realizing a killer deal. You have to appreciate how well thought out, yet simple this scheme really is. Sure, in practice it has a few quirks but those are minor and, up to this point everyone seems to be enjoying Google's AdSense.
