Click Forensics, a Texas-based company that tracks click fraud using detailed campaign data from more than 3,500 marketers, reported that industry-wide click fraud increased modestly in Q1 to its highest level ever: about 15% of all clicks, versus 14% in Q4 2006.
More ominously, click fraud on "content networks"–the third-party advertising solutions that support an ecosystem of thousands of small content companies–increased a more significant 3%, to 22%, from 19% in Q4. This trend is dangerous for small content providers in addition to search engines. A continuation of this trend will soon result in more than a quarter of all content-network clicks being considered fraudulent, a level that could begin to cut significantly into the revenue of smaller content providers.
Also significant: Fraud on high-priced keywords–those over $2 a click–rose to 22% from 21% in Q4, confirming the theory that higher priced keywords are more susceptible to fraud than average- and low-priced keywords.
From the release:
“It appears that click fraud perpetrators are becoming more sophisticated even as search providers step up their efforts to fight click fraud,” said Tom Cuthbert, president and CEO of Click Forensics, Inc. “Click fraud seems to be following a similar path as other online fraud schemes such as spam and phishing – the problem is growing as fraudsters fine tune their methods.”
