ACU (Average Concurrent User)
from Activation
Metrics type
Units of measure
More - better
Check frequency
The mean number of users actively using the app or website simultaneously during a specific time period.
Why it is important
This metric helps businesses make informed decisions about server capacity, infrastructure scalability, and resource allocation to ensure a seamless user experience, especially during high-traffic periods.

Monitoring ACU allows e-commerce platforms to optimize their technology infrastructure to meet user demand and avoid performance issues that could impact customer satisfaction and sales.
Sum of Concurrent Users at each time point / Number of time points
Calculation example
Suppose you want to calculate the ACU for E-commerce Store W on a particular day, and you have data for three different time points:

9:00 AM:
Concurrent Users: 500

12:00 PM:
Concurrent Users: 700

6:00 PM:
Concurrent Users: 600

Sum of Concurrent Users at each time point = 500 + 700 + 600 = 1800

Number of time points = 3

ACU = 1800 / 3

ACU = 600
