This method allows a more detailed analysis of user behavior across different cohorts, says Searchengines.ru. These cohorts can answer the following questions:
- Among those users who made a purchase, how much time passed before the purchase? Is this behavior different from the behavior of users who purchased last week?
- Has your purchase been made in recent weeks?
- Among the buyers who made a purchase last week, how many bought the product again and again? How does this behavior change over time?
