Click fraud a $1.3 billion problem, Outsell says

Published on .

Burlingame, Calif.—Twenty-seven percent of advertisers have reduced their use of pay-per-click advertising because of concern over click fraud, and 10% said they are planning to reduce theirs.

These were among the findings of a Web-based study conducted in May among 407 advertisers by Outsell, a research company. About 15% of advertisers' clicks are fraudulent, according to the study.

Outsell also found the average reduction in spending is 33% and estimated that $800 million is wasted on fraudulent clicks.
