In MoEngage, user count can be analyzed on two different pages - The analytics page and the Segmentation page.
The Segmentation page provides user count and sample user for a segment and Analytics Pages (Behavior, Funnel, etc) provides, event count, event frequency, revenue, retention & funnel information along with the unique user count.
Behavior & Segmentation Users
To analyze users in Behavior Page, select Plot For as Total Users. This option shows unique users for the selected granularity in the line/area chart or overall unique users in the bar chart.
Whereas the Segmentation page shows the overall unique user count.
Few times these two user counts from the segmentation page and behavior page do not match. This may happen due to user merging. In MoEngage engagement Module, the user who is coming from different devices is merged when the user logs in. User Merging is explained in detail here.
The user merging is not available in MoEngage Analytics Module as of now. Hence there are some leftover anonymous users present in the system. A real word person may have 2 kinds of events in analytics, when the user was anonymous and when the user was logged in and hence identified as two different users.
Funnel and Segmentation Users
There can be a difference in funnel user count and segmentation user count. This is primarily due to how funnel and segmentation work.
The funnel considers the order of the event. For a user funnel of event E1 and E2, the final number is users who have done event E1 and after that E2. Users who have performed E2 before E1 are not considered.
Segmentation does not consider the order of the event. For a user segment of events E1 and E2, the final number is users who have done both events, E1 and E2. It doesn't matter which is the first and which is the second event.
