Google Analytics Segments is a subset of your data and concentrates on important users and sessions to perform in-depth analysis. It sticks to a particular data hierarchy and shows the segments that can be created. By default, you are in the All users segment. GA provides ample opportunities to segment users by grouping and comparing them. Many possibilities are available to differentiate users say based on Ad split testing by comparisons of Ads between a group of users, browser types, geography, traffic channels, etc. Segment presents insights across various reports in GA. To create a segment in any GA report, click the Ad segment tab located at the top of the screen. The list options include a segment that GA has created for you. After you have selected anyone from the list the changes will be highlighted in the graphical data allowing you to compare results.
The segment can be used to segregate a subset of data to understand the important changes that exert influence on your data. eg data about a single traffic source or a country. Apply multiple segments and distinguish between single and multiple segments. As seen in Google Analytics Filters and Views, the data used in segments are non-destructive in nature and differs from Views. In other words, it is as if you were looking at filtered data. You can remove the segment and the data will revert back to as it was prior to the application of the segment. Segments provide information on a particular audience without applying a permanent view filter.
