Finally something decent to come from Yahoo – the “Ad Delivery Report” under the Traffic Quality Reports section of Reports tab. This new report gives you insight to impressions, clicks, costs and conversions for the URLs displaying your ads. Use this report to understand which domains to block (via “Blocked Domains” feature).
Per Yahoo:
“The Ad Delivery Report allows you to view:
* a list of domains and specific URLs where your ads were displayed
* performance metrics for your campaigns in terms of impressions, clicks, cost, conversions, etc by URL (Analytics must be installed to track conversion data. Learn more about installing Analytics)
* information about how certain URLs are performing, potentially enabling you to make better decisions when using the Block Domains feature
