How can I categorize my Analytics data in Piwik PRO?
Segmentation is a method to obtain a selected portion of your analytics data rather than the all of your aggregated data. It is used to create groups of visitors from different locations, specific device users, or visitors who interact with your website/application in a particular way. You can generate reports for selected visitors according to custom criteria.
Segments can be defined by selecting various parameters that are joined by logic operators such as AND and OR. To take a look how to easily implement a segment in your Piwik PRO instance, see our article.
