The idea of cohort analysis is to divide the customers into groups with the accordance to certain characteristics, and to monitor the behavior of these groups through time.

Usually, user groups (cohorts) are segregated on the basis of weeks (months), when people started using the application. Having selected such user groups (cohorts), you follow them through time and measure key metrics for each cohort. Thus, comparing the data of the March and May cohorts of users, you can objectively compare versions of the product corresponding to these time periods.

For more profound analytics selected cohorts must be further segmented on the basis of the traffic source, platform, country and other factors that make sense for your particular product.

It is highly possible that, the value of your key metrics will be different for different segments, as well as various product changes will have a different impact on different segments of users.
