Yahoo! Search Marketing wants advertisers to understand that traffic quality and click fraud are two very different things. Click fraud is generally considered to be clicks made with bad faith with the sole purpose of generating a charge to the advertiser with zero possibility of a legitimate site visit or transaction occurring. From a technical perspective, Yahoo! Search Marketing has to look at what identifiable behaviour may indicate bad faith. In terms of identifiable behavior, we define click fraud as detected illegitimate bots and certain repetitive clicks. And we have created sophisticated software that identifies this behavior and attempts to filter out charges for these clicks so that you are not billed for them. We do not disclose how we define repetitive clicks or the details about our proprietary technology because we do not want to educate those who are acting in bad faith.

Traffic quality clicks refers to all clicks that are not click fraud, which includes everything from perfectly converting clicks to those that do not convert. It refers to clicks from domestic and international users and clicks from our various distribution channels and products. We realise that advertisers are concerned about traffic quality issues such as receiving traffic from unwanted sources or increased amounts of traffic and are happy to address any questions they might have in this area.
