One of the most popular and powerful features in Google Analytics is Advanced Segmentation. It lets you isolate and analyze subsets of your traffic. You can select from predefined segments such as "Paid Traffic" and "Visits with Conversions" or create your own segments with a flexible, easy-to-use segment builder. Then, you can apply one or more of these segments to current or historical data, and even compare segment performance side by side in reports. We think you'll love it.
