Click Defense’s focus in the class action lawsuit (which could potentially involve other companies on either side – plaintiff or defendant) is that although Google admits that click fraud exists and that it is a serious risk to their own profitability, as well as stating they are doing what they can to combat the risk; however, they are not doing all that they could do to counteract click fraud and are not sincerely considering refund requests from advertisers.

The lawsuit aside, what exactly does Click Defense bring to the table of the variety of tools that have recently arisen on the scene to deal with click fraud, as well as its web analytics’ side? The Colorado-based company bills itself as “the leading ad tracking, optimization and click fraud detection company” and has been in business since early 2002.

Click Defense equates click fraud with “ad spamming,” (sometimes calling it “click spamming,”), but click fraud is not spamming in the usual meaning of the term – it involves fraudulent clicking on PPC ads, rather than sending mass emails or ads out to recipients who did not request them – the usual definition of spam. Leaving semantics aside, click fraud detection is only one part of this company’s business – they also provide detailed web analytics and content personalization.

Click Defense offers three different reports to its clients:

Repeat Clickers Report – provides you with the IP address, number of times your ad was clicked, the dates the clicks were made, the pages viewed and session lengths for those clicks, and any sales/conversions that arose from those repeat clickers.
