Click Fraud Adsense | 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.
Identifying and tracking examples of click fraud is the first step to eradicating the problem. Click fraud is an enormous drain on the resources of advertisers operating on a national and international scale, estimated to occupy around 30% of all pay per click advertising spend. With so much at stake, its no wonder the search engines are investing so much time and effort into devising solutions.
One way in which Search Engines and other pay per click programme providers have attempted to curb the growing click fraud problem is through introducing IP address repetition algorithms. These formulae are designed to pick up on suspicious click patterns emanating from a singular IP address, which can help to uncover the existence of click farms and competitor-led sabotage, as well as identifying potential fraudsters at source.
However, there is an array of problems with this method of attempting to identify the fraudsters. Firstly, fraudsters logging on through a dialup modem, DSL line or cable modem can almost completely bypass this check, as with every new online session, a new IP address is generated. Furthermore, there is an extensive range of software available to alter IP addresses, which again can be used for 'cheating' the algorithm. Cookie and session tracking are other methods by which search engines can attempt to uncover potential fraudulent activity, but again there are ways around these for the fraudsters.
More comprehensive software is being developed which profiles and reports on the browsing habits of each click-through to enable companies to track and monitor suspicious behavior, although this could be seen by many as intrusive and ineffective as anything on a small scale is still likely to go unnoticed, based on the vast coverage of ads across the internet.
The problem of click fraud recently hit the headlines with a class action raised against Google, prompting Google to offer $90million as a potential settlement. Perhaps an acceptance of their responsibilities, Google's offer goes some way to suggest the extent of click fraud, and its vast costs to the internet economy.
There are a number of self-help remedies that can be implemented to keep an organization out of trouble. The first of these remedies is the reliance on search engine optimization and organic listings. If a site is well and fully optimized, it could eventually realize a ranking that another site is willing to pay $2.50 a click for. Similarly, with organically high rankings there are no clickthrough rates, therefore the costs associated with PPC are not applicable. Although the process is significantly more laborious and takes significantly longer to see results, the SEO process is much cheaper in the long run, and with an estimated 25-30% of all clicks being performed fraudulently, an organically high listing can save money which would otherwise be drained by click fraud for more beneficial reinvestment.
Year on year, as the pay per click advertising market continues to grow and expand, surely click fraud will follow suit. Unless an effective means of preventing click fraud is developed and successfully implemented, buyers will steadily lose confidence in the advertising medium and turn to more effective, less wasteful marketing methods, which would seriously hit the search engines and could potentially threaten the online economy as a whole.
