Click Forensic’s quarterly assessment of overall click fraud rates for the paid search industry says that click fraud has increased to 22.3% in the third quarter of this year, up from 18.6% last quarter. There has been a consecutive rise in click fraud rates over the past 18 months, from the 17.4% Click Forensics reported for Q1 2010 and the 12.7% rate reported for Q2 2009.
Traffic across more than 300 ad networks, as well as billions of clicks from top search engines, comparison shopping engines, social networks, leading publishers and advertiser web sites is reflected in the data.
Countries outside North America with significant CPC traffic producing the greatest volume of click fraud were Japan, the Netherlands, the Philippines and China, respectively. Click Forensics reported that they observed a growing volume of click fraud flow through a more diverse number of sources, including mobile proxies. The company is advising advertisers to be vigilant about the quality of traffic they receive as more ads are placed in videos, social networks and on mobile devices.
