All, We’ve launched the Click Filter Report, which is a new report that provides information about the number of clicks on your ads that our Click Protection System has identified as invalid and, as a result, we did not charge you for. You can find the Click Filter Report under the “Reports†tab in your account: Just select “Click Filter†in the “Traffic Quality Reports†section of the Reports Navigator on the left side of your screen. The report can be customized with the following data: •Impressions •Clicks •Invalid Clicks •Invalid Click Rate •Click-through Rate (CTR) •Cost •Average Cost-per-Click We’ve posted a more detailed article about the Click Filter Report on the Yahoo! Search Marketing Blog: http://www.ysmblog.com/blog/2008/04/22/click-filter/ Hope this helps! - YahooPete
