Cohort analysis - User retention in a Rails application.
I want my actions to be more data-driven. I want to make Dave McClure, Steve Blank, and Eric Ries proud. Easier said than done.
Analytics is still a pain in the ass.
How can I tell if people are using my product, Draft? (Draft is the tool I’m working on to help people become better writers.)
I could look at user retention. Once people start using Draft, do they come back to use it again?
There’s some great software to help study how users return to your product. They use a method called cohort analysis, which breaks up users into groups of people who “activate” or sign-up at the same time and then you track their progress as a group. Do users that signup in January after one month use your app more than those users who signed up in December after their first month? They do? Awesome, those features and things you did in February might be onto something.
To use these analytics...
