Click fraud costing $1 billion p.a.

Posted by Michael Bloch in web marketing (Tuesday February 28, 2006 )

According to information in a recent article on Business Week, click fraud could account for up to 20% of all PPC traffic and be costing advertisers up to $1 billion per year.

What the real figures are is anyone’s guess, but if you’re investing in Pay Per Click, it’s wise to be aware of what can happen. In the Business Week article, I noticed some quotes from Dimitry Eroshenko, the CEO of ClickLab. Back in 2004, Dimitry and I teamed up to publish a white paper on click fraud. The information in that white paper is still relevant today.
