Behavior based segments in terms of tracking are a group of accounts that can be grouped for analysis based on a shared behavior.
Behavior-based segments refer to groups of users who have similar behaviors or patterns of usage within a product or service. In user onboarding, behavior-based segments can be used to track how users are engaging with the product or service during the onboarding process. By analyzing user behavior, companies can identify which segments of users are struggling with onboarding and which are succeeding, and can then tailor their onboarding strategies to better meet the needs of each segment.
