Google announced today that Bid Adjustments reports for AdWords enhanced campaigns are now included in Google Analytics.
The reporting, found in the Advertising section under Traffic Sources in Analytics, are designed to help advertisers analyze the performance of each bid adjustment within a campaign — by device, location and time of day.
You’ll notice in the Google-provided screenshot example above, there are columns for Revenue and Ecommerce Conversion Rate in the Summary view. These metrics are available when Ecommerce tracking is enabled in Google Analtyics, allowing you to analyze bid adjustment performance by ROI. However, when you look at your own reporting, you may see that the Summary view only shows goal results and that the columns for Revenue and Ecommerce Conversion Rate appear under the Ecommerce view instead.
