Click Forensics, Inc., a provider of click fraud prevention solutions, recently announced the availability of Click Forensics for Publishers. The new product allows online publishers and ad networks to automatically block sources of click fraud and poor-quality traffic from hitting pay-per-click (PPC) advertisements running on their sites, according to the company. Similar to a spam filter, the product filters out click fraud and other low quality traffic in real time so publishers can improve the overall quality of the traffic they pass through to advertisers.
