Google's main income source is at risk because it can't distinguish between a person and an automated fraudster. Adsense brings in about $6 Billion a year to Google.
I am sure all of you would have heard of Google's Adsense program by either seeing it on other sites or clicking on few of them. These are ads that are placed by Google on other network of sites. When a visitor click on those ads Google will pay the host site owner. Websites didn't have this sort of flexibility in making an income before Google introduced this sort of revenue stream for websites. As it sounds easy it is also easy for fraudsters to fraud the system to make easy money. Depending on the keywords or the contents in your site, Adsense will pay a lot more. Sometimes the revenue will be as high as 1o to 25 dollars per click. This is huge money for websites that was not making any money before. So with these perks comes the urge to fraud the system.
There are two kinds of fraudsters. One trying to beat the system to make money and other one is trying to beat the system to crash their competitor.
What do I mean by these two types? Well the first one is easy. As explained above, a host site owner will implement automated scripts or programs that will click on Adsense ads. This will help accumulate a decent revenue for the host site. Google does not make this easy for people to fraud their system but fraudsters are smart just like scammers. You upgrade your system and they upgrade their skill level to beat the system. So it is an ongoing problem for Google.
The second is when one of your competitors is trying to beat the system so that you end up paying for false clicks. If you are a customer for Google Adsense (Adwords) and your competitor finds out so he setup a fraud machine to click on your ads. It costs you every time it clicks on your ad. Soon you will go in debt and quit advertising. Google and you will loose on this one.
So Google is now looking at other ways of selling advertisements. One way is to imitate the famous "affiliate program" into a "cost-per-action" program. Yes Google is recently testing a new advertising model called the cost-per-action. It means Google will only charge you a click through actually ends up in a signup, posting, purchase or some sort of action on your site. You may be thinking that this sounds familiar. Yes damn right. This is the famous affiliate program that we all take part in. This is actually a better way for Google to get out of their fraud issue but will this save the consumer at the end of the day? Imagine you purchase cost-per-action ad from Google to have customer’s signup for a survey of some sort. All of a sudden you got 1000 surveys completed in no particular order. Google is happy that they sold 1000 survey postings for your site. They charge you and you pay them. Then you find out that these survey results are totally misleading. Well then you try to figure out what the heck people were smoking when they were filling out your survey. Well you could pretty much conclude that it was smoking off heat when it was filling out your surveys. It being an automated program...
