The Segment Builder utilizes a container architecture that lets you determine what to include in a segment. The Visitor container is the outermost container and includes overarching data specific to the visitor across visits and page views. A nested Visit container lets you set rules to break down the visitor's data based on visits, and a nested Hit container lets you break down visitor information based on individual page views. Each container lets you report across a visitor's history, interactions broken down by visits, or break down individual hits.
