Companies using pay per click services may be pleased to hear that pay per click (PPC) fraud rates fell during the first quarter of the year.
Research from Click Forensics show that the average click fraud rate in the first three months of 2009 was 13.8 per cent.
This is down from 17.1 per cent in the final three months of 2008 and is also a large improvement on the 16.3 per cent rate seen during the same period a year ago.
Tom Cuthbert, president of Click Forensics, said: "It appears that the drop in keyword cost per clicks and the progress Yahoo! and Google made blocking click fraud from botnet sources contributed to the decline in the overall click fraud rate this quarter."
The research shows that the largest proportion of PPC fraud outside the United States came from the UK, Canada and Germany.
Meanwhile, according to research from Guava and Econsultancy, some 45 per cent of companies plan to spend more on PPC marketing this year.
