Segments are also useful because they allow you to dig deep into questions. Questions that are likely going to appear in your mind as you get on with the business of looking at your reports.

For example. In our module on the reporting interface, one of the demo use cases we talked about looked at demographics. We found that whilst we had more male users, the ladies spent more. So you may start to think, what did they buy? What cities are they from? What marketing channels brought them in? What content did they look at?
To get those answers you could create a Segment to only show users that match the demographic dimensions and metrics that are of interest to you.
This template will explain why you should get excited about Segments, the Pro’s and Con’s of Segments. It explains the very important concept of scope, and how a Session Segment is different from a User Segment.
