Cohort analysis

In this article, you will learn everything you need to know about Cohort analysis.

Cohort analysis definition

Cohort analysis is a statistical technique used to evaluate the behavior and characteristics of a group of individuals over time. It is often used in business and marketing to understand how customer behavior changes over the course of their relationship with a company. By analyzing data from a cohort of individuals, businesses can gain valuable insights into how to retain and engage their customers, as well as identify potential areas for growth and improvement.

In its simplest form, cohort analysis involves dividing a group of individuals into distinct subgroups, or cohorts, based on a common characteristic or behavior. For example, a business might divide its customers into cohorts based on the month in which they made their first purchase. This allows the business to compare the behavior of customers who made their first purchase in January to those who made their first purchase in February, and so on.

Cohort analysis benefits

Once the cohorts have been defined, the business can analyze their behavior over time. For example, the business might look at the average purchase amount for each cohort, or the percentage of customers who make a second purchase. By comparing these metrics across different cohorts, the business can identify trends and patterns that can inform its marketing and retention strategies.

One key advantage of cohort analysis is that it allows businesses to control for external factors that may influence customer behavior. For example, a business might see a decrease in sales during a particular month due to a recession. By using cohort analysis, the business can isolate the effect of the recession on sales, and compare it to the behavior of customers who made their first purchase during a different time period. This can provide valuable insights into how external factors influence customer behavior, and help businesses plan for and mitigate potential risks.

Another advantage of cohort analysis is that it allows businesses to identify opportunities for growth and improvement. For example, a business might see that customers who make their first purchase during a particular month have a higher average purchase amount than those who make their first purchase during another month. This could indicate that there is an opportunity for the business to target marketing efforts towards customers who are likely to make higher-value purchases.

How do you do a cohort analysis?

To do a cohort analysis, follow these steps:

1. Identify the group of individuals that you want to study, and divide them into distinct subgroups, or cohorts, based on a common characteristic or behavior. For example, you might divide a group of customers into cohorts based on the month in which they made their first purchase.
2. Collect data on the behavior and characteristics of the individuals in each cohort. This might include metrics such as the average purchase amount, the percentage of customers who make a second purchase, or the average time between purchases.
3. Analyze the data for each cohort, and compare the results across different cohorts. This will allow you to identify trends and patterns in the data, and to see how the behavior of the individuals in each cohort changes over time.
4. Use the insights gained from the cohort analysis to inform your business or marketing strategies. For example, you might use the analysis to identify opportunities for growth and improvement, or to develop targeted marketing campaigns for specific cohorts of customers.
5. Monitor the behavior of the individuals in the cohort over time, and continue to update and analyze the data as needed. This will allow you to track the effectiveness of your strategies and make any necessary adjustments.

Overall, cohort analysis is a powerful tool for businesses looking to understand and improve their relationships with their customers. By dividing customers into distinct cohorts and analyzing their behavior over time, businesses can gain valuable insights into how to retain and engage their customers, and identify potential areas for growth and improvement.
