Retention today is even better – you can define cohorts by any event and properties.
See it in action here: https://mixpanel.com/blog/2013/08/13/chewing-on-retention/
We rolled out some big changes to the way retention reports work. Now you can
slice and dice your retention data the same way you can in the Segmentation
To our existing customers, the biggest change is in the way cohort groups are
determined. In the past, you could only select a single event for retention
analysis, now you can select two – one for determining the cohort (usually you
would pick a signup or $born event for this) and one to look at the retention
for. This is explained in detail on our documentation
page, and in
the video below the fold.
You may be wondering: “what happened to compounded retention?” Now all
retention is compounded retention – when you pick the first event, we will
include all users in the cohort who fired that event, not just those who fired
it the first time. To see birth retention, you need to fire an event that will
only be sent once and determine the birthday for each user. This event can be
called whatever you want, but we recommend calling it $born or
$signup. To learn how to import these events for your existing users,
check out this blog post.
If you have any questions about new retention, we will be hosting a Live Q&A
Webinar tomorrow at 11 AM PST. To tune in visit
