Anchor Intelligence released their click fraud report today, reporting that click fraud has reached an all time high. The “Attempted Click Fraud” rate rose 13.4% from 25.7% in the fourth quarter of 2009 to 29.2% in the first quarter of 2010. Year-over-year, this is up 34% from Q1 2009. It is important to note that “attempted click fraud” is not necessarily charged to advertisers.
