Click Fraud Rate

As reported by Click Forensics Click Fraud Rate is fast climbing.

Main evidences:

The overall industry average click fraud rate was 15.8 percent for Q2 2007. This is an increase from 14.1 percent for the same quarter in 2006 and 14.8 percent for Q1 2007.

The average click fraud rate of PPC advertisements appearing on search engine content networks, including Google AdSense and the Yahoo Publisher Network, was 25.6 percent.
That’s up from 21.9 percent for Q1 2007 and 19.2 percent for Q4 of 2006

Traffic from botnets doubled from Q1 to Q2 2007 and contributed significantly to the increase in click fraud rates.

In Q2 2007, the greatest percentage of click fraud originating from countries outside North America came from France (5.1 percent), China (3.2 percent) and Australia (3 percent).


It's quite obvious that informations on how frauds affect PPC campaign and ROI might be useful to gather.

Click Fraud Network offer a tool to track up to 100.000 clicks per month.
It's called ClickForensic, and it's free (probably one starts to pay for a higher click number, or probably they would try to sell some "antidote tool"... no idea)
(Quite curious the extra-US origin of click fraud, and what's more I read about the research on an italian blog... )
However, I would try it (the free service).
