Click Forensics today released industry pay-per-click (PPC) fraud figures for the fourth quarter 2008 from the search advertising industry?s click fraud reporting service ? the Click Fraud Index.
Now in its fourth year, the Click Fraud Index monitors and reports on data gathered from the Click Fraud Network, which provides statistically significant industry PPC data collected from online advertising campaigns for both large and small companies across all the search engines. Key findings from data reported for Q4 2008 include:
- The overall industry average click fraud rate grew to 17.1% for Q4 2008. That?s up from 16.0% in Q3 2008 and from the 16.6% rate reported for Q4 2007.
- The average click fraud rate of PPC advertisements appearing on search engine content networks, including Google AdSense and the Yahoo Publisher Network, was 28.2%. That?s up from the 27.1% rate reported for Q3 2008 and down slightly from the 28.3% rate reported for Q4 2007.
- Traffic from botnets was responsible for 31.4% of all click fraud traffic in Q4 2008. That?s up from the 27.6% rate reported for Q3 2008 and the 22.0% rate reported for Q4 2007.
- In Q4 2008, the greatest percentage of click fraud originating from countries outside the U.S. came from Canada (7.4 percent), Germany (3.0 percent) and China (2.3 percent).
"Based on the data we tracked in Q4 2008, it seems that the online advertising industry is not immune to the growing tide of cybercrime during this recessionary period," said Tom Cuthbert, president of Click Forensics. "Both the overall click fraud rate and the rate of click fraud originating from botnets were the highest ever in Q4 2008. In addition, we?ve started to see old schemes like click farms reemerge. Advertisers should pay close attention to these types of threats in their online campaigns throughout the year."
The Click Fraud Index publishes data collected from the Click Fraud Network, a third-party click fraud detection service dedicated to helping companies more accurately monitor their online advertising campaigns for pay-per-click fraud. Click fraud data is tracked and published on a quarterly basis for specific search providers, industries and trends. The service is unique in that it monitors online campaigns for click fraud by correlating data collected from search provider campaigns and the advertisers? own web sites.
