Google announced today that it is adding bid adjustment reporting to Google Analytics to help advertisers optimize their enhanced campaigns. The feature will let you analyze performance for each bid adjustment across devices, locations and time of day.

The new report can be accessed under Traffic Sources > Advertising > Adwords. From there, just click the Bid Adjustments link.

“With the new Bid Adjustments report, you can take advantage of the full range of visitor metrics available in Google Analytics to optimize your bid adjustments,” says Google Analytics product manager Nikhil Roy. “This provides a window into your users’ behavior, allowing you to optimize bid adjustments based on behavior & goal conversion data like bounce rate and time-on-site.”

“In addition, with Ecommerce tracking enabled in GA, you can now use this data to fine-tune your bid adjustments in AdWords based on the actual revenue generated, instead of conversions,” adds Roy. “This means you can optimize for ROI instead of CPA goals.”

The new report is available in all Analytics accounts that are linked to Adwords.
