AdWords offers a variety of ways to track the performance of your ad account, but most of it is focused on the clicks. However, knowing what people are doing after clicking on an ad is as important as simply evaluating the AdWords account performance. On the May 4, at San Jose's Emetrics conference, we just released a new set of AdWords reports from Google Analytics to help you figure out the problem.
The new AdWords report in Google Analytics gives you more information about what the visitor clicks on the ad. For example, suppose you want to see whether potential consumers searching for exact matching keywords are more interested in the content of the site than those who enter the site from a wide range of matching keywords. Then you can look up all the keywords in the new report that click on the exact matching advertiser, and the ad group and promotion plan in the account. You can also see the number of pages visited by that group and the average site stay time. If you're using a Google Analytics filter report, you can even see which step the visitor has stopped during the purchase.

I hope these reports will make it easier for you to evaluate the success or failure of your promotional program.
