Making money online through Adsense and other ad networks

One of the biggest threat to the Pay Per Click business model is click fraud.   We heard about lawsuits about click fraud and the recent $90million google settlement. 
Now, major web search engines announced plans to work together to quantify click fraud and hopefully, work together to combat it.

Click fraud occurs when online ads are intentionally clicked on, either by Web sites who get paid for hosting the ads or by companies trying to deplete the ad budgets of rivals so they can buy the search keywords themselves and steal the business.

The Interactive Advertising Bureau (IAB) and the nonprofit Media Rating Council said they are teaming with Google, Yahoo, Microsoft, Ask.com, LookSmart and others to form the Click Measurement Working Group.

The group's mission is to establish guidelines for what constitutes valid clicks and invalid clicks on ads. Guidelines can help the industry measure how prevalent click fraud really is. Third-parties who sell click-fraud-combating services to advertisers claim that click fraud rates are as high as 30 percent. Google and Yahoo counter that click fraud rates are minimal.

As people who use adsense and similar pay per click publishing platforms,  click fraud would only mean lesser income for the same amount of traffic.   If click fraud continues,  I bet more advertisers would either stop using PPC or bid keywords at a lower price.    This means less income for us publishers.

The click per action (CPA) model is slowly becoming a good alternative.  I hate to see the time when cost per click is no longer  a viable advertising model.
