Search Engine Marketing Professional Organization Teams with Fair Isaac to Research Click Fraud

SEMPO, a non-profit professional association working to increase awareness and promote the value of search engine marketing worldwide, and Fair Isaac, the leading global provider of analytics and decision management technology, will be co-sponsoring the study, which Fair Isaac launched in March. The study will use artificial intelligence methods to determine the extent of click fraud in PPC advertising and develop a solution for the search engine industry.

Fair Isaac's fraud and identity theft detection solutions are known worldwide for their effectiveness in helping businesses across industries cut fraud losses and protect their customers from fraudulent transactions. Fair Isaac's Falcon One™ suite of interlinking enterprise fraud solutions enables businesses to improve their protection across channels and business lines leveraging the company's market-leading Falcon™ technology, which has been successfully used to fight payment card fraud for 15 years.

Fair Isaac scientists believe the anti-fraud technology used to protect 450 million active payment cards worldwide may also help in differentiating between Internet advertising "clicks" that are genuine expressions of human interest and those that are not.

SEMPO Chair Gord Hotchkiss said, "Click fraud is probably the single biggest deterrent to the continued growth of search engine marketing today. As search expands into new markets, including local advertisers, marketers have to feel confident that they're getting full value for every click. It's a question of trust, and the beginning of that trust must come from a reliable assessment of the scope of the click fraud problem. No one has a better track record than Fair Isaac in identifying fraudulent patterns and eliminating them. Search engine marketing is an incredibly efficient marketplace, and will become even more so when we can more effectively control click fraud."

"Fair Isaac and SEMPO share an interest in the economic importance of properly assessing the value of Internet advertising," said Ted Crooks, Vice President of Global Fraud Solutions at Fair Isaac. "Our partnership with SEMPO is an important milestone in our research investigation into click fraud. It creates the opportunity for us to analyze a larger pool of data from a wide range of advertisers to determine the overall extent of click fraud with more precision as well as understand variations in fraud patterns with advertiser characteristics."

The planned study will analyze several mathematical methods of scoring and vetting advertising charges with emphasis on required data and the value of specific, alternative data sources. Specifically, the organizations will attempt to learn what combinations of data and sources are most important in the accurate rating of Internet advertising services. In general, the methods applied will leverage artificial intelligence by using systems that rely upon neural networks and similar techniques trained to recognize patterns through repetitive analysis of historical cases.

SEMPO members and non-member PPC advertisers will have an opportunity to contribute anonymous click stream data to this study. In exchange, they will receive meaningful analysis of their search engine advertising and potential click fraud. SEMPO Research Committee Co-Chair Kevin Lee commented, "This is an opportunity to get free insight into the click quality drivers in a campaign, and marketers should jump at the chance to participate."
