Definition
A retention cohort is a group of users or accounts who started using your product in the same time window, such as a week or month.
Why retention cohorts matter in PLG
Cohort analysis helps you see whether newer groups are retaining better or worse than older groups, especially after you change onboarding or pricing.
Using retention cohorts to improve PLG
By comparing cohorts before and after you change onboarding or pricing, you can see whether those changes improved or hurt retention.
You can also use cohorts to identify segments that retain especially well and design more targeted PLG programs for them.
