Click Fraud Keeps Rising, Up 15 percent in 2007
While the year-over-year growth is cause for concern, the click fraud rates remained pretty steady compared to the third quarter of 2007, when the overall click fraud rate was 16.2 percent and the search-engine click fraud rate was 28.1 percent (see charts above). One quarter does not make a trend, but could the click fraud rate be leveling off? One can hope. If Google can ever get that rate to actually go down, maybe its stock will shoot up again.
Click Forensics also published the handy heat map below showing the countries where the most click fraud is originating. (Red is bad, green is benign). The biggest sources of click fraud are India (4.3 percent), Germany (3.9 percent), and South Korea (3.7 percent). Mexico is also in the red.
