What is Cohort Analysis?
Cohort Analysis is a descriptive analytics tool, a subset of behavioral analytics that takes data from a given data set and rather than looking at all users as one unit, it breaks them into related groups for analysis.
These related groups, or cohorts, usually share common characteristics or experiences within a defined time-span.
Definition
It sounds technical, but in fact, is a method of behavioral analytics that enables organizations to consider a particular group of users or customers over a specified timescale.
It’s an intelligence tool for understanding customer behavior and improving, marketing, sales, and user experience.
Purpose
The main aim of cohort analysis is to identify relationships between the characteristics of a subpopulation and that subpopulation's behavior with respect to your product.
In simple terms, it's there to answer questions like "do users who sign up during holiday sales spend more than average?".
Scope
If used right, cohort analysis can give fantastic insights into both your user base and product use.
It allows for targeting marketing efforts on specific sections of your user base that are likely to give you the best return on investment.
Importance
Why is it important, you ask? Well, it's a very effective method to understand the effect of partialities that exist in your user base.
Since it observes and scrutinizes finer details about customer behavior such as time-to-conversion, churn rate, etc., it helps provide insights valuable for creating personalized experiences and user retention.
Origin
This fascinating research method isn't new. The term "cohort" is derived from the Latin "cohors," and its roots can be traced back to the fields of medicine, sociology, and life-course studies.
Who Uses Cohort Analysis?
Let's now look at the different players in a business who can make the most out of a Cohort Analysis.
Marketers

Major Changes Afoot? Do a Cohort Analysis.
If there are any updates in your market, product, or internal policies then it's time for Cohort Analysis to understand the impact of these changes on different cohorts.
Data Needed for Cohort Analysis
Cohort Analysis is data-driven. But what data do we need exactly?
User Acquisition Dates
When did your users join or get acquired? This information forms the foundation for cohort division.
Behavioral Data
That's right! You need detailed data about how customers interact with your product or services over time, and how their behavior evolves.
Demographic Information
Guess what? Demographics can have a significant impact on behavior. That's why we need data about the user's age, location, sex, etc.
Transactional Data
We're talking about purchase dates, purchase frequency, purchase size, and product preferences. They're crucial data, especially for e-commerce or subscription-based models.
Engagement Metrics
You would want metrics like session length, frequency of use, and feature interactions. They are key indicators of user engagement and can offer a wealth of insights.
How to Perform Cohort Analysis?
Now the biggy - the "how-to" of Cohort Analysis. But don’t worry, you got this. Let’s break it down into steps.
Objective Definition
Start with a clear objective. It's important to know what you want to achieve or learn from the Cohort Analysis. This guides your entire analysis process.
Segmenting Data
Once you have the data in hand, the next step is to segment your customer data into cohorts.
Selecting the Right Metrics
To get meaningful insights, define the metrics that align with the goal of the Cohort Analysis. Measure these metrics across cohorts over time.
Data Analysis
Next, we get down to analytics. Use data visualization tools to make these analyses visually accessible and more intuitive.
Result Interpretation
What's the story from your data? Connect the dots from data to insights, fleshing out the insights story. Use these to guide your strategic decisions.
