In explorations, what does segment overlap show?

• A. It highlights how customer journeys differ between devices.
• B. It shows how different user segments relate to each other.
• C. It tracks lifetime value of users across cohorts.
• D. It counts the number of sessions for each day.

Answer: (B)

Segment overlap reveals how different user groups relate to each other by showing the shared audience between segments and the size of those intersections. When you compare multiple segments—like desktop versus mobile users or users who purchased versus those who only browsed—the overlap visualization shows how many people fall into both segments. This helps you see whether segments cover the same people or distinct audiences, guiding cross-targeting, messaging, and where to allocate effort. It also indicates incremental reach: a large overlap means focusing on one segment may already include much of the other, while a small overlap points to more separate audiences needing tailored strategies. It’s not about lifetime value across cohorts or daily session counts.
