A Brief Insight to Cohort Analysis: the All-in-One Behavioral Analysis Tool

Of late, more and more businesses are adopting the concept of cohort analysis to measure the extent of customer satisfaction. What is cohort analysis? In a few words, it is the assessment of users into compartmentalized groups, based on shared characteristics, instead of an entire unit.  Cohort analysis marketing is where a company isolates patterns within the daily activities of its users and based on these patterns they can tailor specific services to destined cohorts. On certain occasions, cohort analysis relates to a cohort study, though they are not the same and one should not see them as equal.

Benefits of cohort analysis

It enables an organization to find out models transparently across the user or customer life cycle, instead of following all the customers thoughtlessly, not taking into consideration the natural cycle that a customer goes through. After the organization views these time models, it can adjust and modify its services to those particular cohorts. 

Actionable cohort analysis lets companies into a better understanding of user behaviors, enabling them to distinguish between growth and engagement metrics. Oftentimes, the aggregate growth masks the selective statistics of usage from the pre-existing customer base by new incumbent customers.customer_cohort
Let’s take the example of a gaming platform to illustrate the above point. A gaming platform has two cohorts. One that is made up of expert gamers, an older base, and new another one comprising of new signups. The former is concerned more about advanced features like the lag time on the game, than the latter.

Due to a customer cohort analysis, the platform would see that a slight lag in load time or run time. This lagging is a complaint coming only from expert gamers, which is leading to loss of revenue. Moreover, this would also halter new sign-ups as reviews from expert gamers can affect new signups. Had it been an all-pervasive report, such a difference would have gone unnoticed.

How to do a Cohort Analysis?

A cohort analysis is conducted on the summation from two key data points, acquisition cohorts, and behavioral cohorts.


  • Acquisition cohorts, as the name suggests, is the division of users based on the time of acquisition of a service. For an app service, the cohorts are broken down based on the day, week, or month of signing-up and how long they have been in acquisition of the said app(s). The data accumulated from these cohorts allow you to determine how long people have been hooked on your app service. For the cohort analysis in Google analytics, right now, the acquisition is the only parameter for determining cohorts.
  • Behavioral Cohort Analysis will target the usage of your customers over a given period; These could be any actions like app install, uninstall, app launch, updates, purchases, notifications, using a particular feature, etc.how to do cohort analysis

A Few Crucial Points For Cohort Analysis

  • What do you want to know? Vanity metrics can be misleading as it puts shade to the varied user bases and puts forth a generalized image of growth but not engagement. It is, therefore, crucial to identify what actionable information can be gathered to offer a better user experience on your app or website. All the more reason for relying on a cohort analysis report.
  • Identifying the metric that will answer your question. A proper cohort analysisremember for cohort needs a metric that serves as a standpoint based on which the cohorts will be analyzed. For instance, how much of the gamers are willing to buy game credits based on the amount of lag time on a gaming platform.
  • Defining cohorts. Each cohort will function uniquely. For successful cohort analysis marketing, one must target them or ascertain how they contribute to their behavior as a cohort. Maintaining the instance of a gaming platform, the cohorts of advanced and beginners will have different attributes and resultantly, different campaigns, and promotions.

Cohort analysis Python

Cohort analysis PythonCohort analysis is an effective and comparatively easy means to gather useful perceptions concerning the customer/user behavior of any business.  To perform the analysis, you can concentrate on various metrics (subject to the pattern of business) such as retention, churning, revenue generated, and so on. Users can also perform analysis in a highly sophisticated programming language like Python. Cohort analysis Python takes place with the seaborn and pandas of Python. Seaborn is a library for generating statistical representations in Python. Pandas is a software library authored for the Python language for the assessment of data and data handling. Pandas is available for free and has a wide-ranging application in computer programming.

Tableau cohort analysis

Tableau cohort analysisTableau cohort analysis is about carrying out cohort analysis and delving into various combinations for realizing the customer inclinations, cause and effect associations, and what will probably occur to participants of a specific cohort with time. Users perform it with Tableau Desktop data visualization software. 

SQL cohort analysis

SQL cohort analysisStructured Query Language is a domain-oriented language for programming. It was innovated for handling data kept in an RDBMS (relational database management system) or stream processing in an RDBMS. Thus, SQL cohort analysis helps find out cohort retention with basic SQL tables.

Analysis of cohort studies: Prospective and retrospective cohort analysis

Analysis of cohort studies can be broadly categorized into prospective or retrospective cohort analysis and they are dependent on the results taken place in association with the participation of the cohort. These studies are particularly relevant in the field of healthcare.

In a prospective cohort study, the extraction of standard data takes place from all cases. Furthermore, there are precisely similar questions and data extraction methodologies for all the cases. The researchers devised the questions and data extraction methodologies cautiously for procuring exact details on vulnerabilities ahead of the ailment occurring in any of the cases. After the extraction is over, researchers subsequently monitor the cases in a prospective cohort study “longitudinally”, that is, throughout a particular period. This period typically lasts several years. This is to ascertain if and when they get ailed and whether their vulnerability condition varies.

Analysis of cohort studiesIn this manner, researchers can gradually utilize the data to reply to a multitude of questions. Questions regarding the relations between the ailment results and risk elements. For instance, one can distinguish alcoholics and teetotalers at standard. Then perform a comparison of their success rate of getting cardiac ailments. As a substitute, you can categorize cases according to their BMI (Body Mass Index) and perform a comparison of their possibility of getting cancer or cardiac ailments.

On the other hand, the concept of retrospective cohort analysis comes into effect once some individuals have already got the results of interest. The researchers move backward in time to recognize a cohort of persons at a juncture ahead of their getting the results of interest and they attempt to prove their vulnerability condition at that moment. Subsequently, they ascertain whether the case got the result of interest afterward.

The characteristic aspect of the prospective analysis is when the researchers start registering cases and gathering standard vulnerability details, none of the cases has got any of the results of interest. Instead, the distinctive aspect of a retrospective cohort analysis is that the researchers conceptualize the analysis and start recognizing and registering cases once results have already taken place.

R cohort analysis

R cohort analysisR cohort analysis is the technique of developing a cohort chart or table in the R programming language. It is a free programming language for statistical representation and computing. For executing R cohort analysis, you need to use ggplot2, a data visualization software for the R statistical programming language. Hadley Wickham designed ggplot2 in 2005, and it is an application of Grammar of Graphics by Leland Wilkinson. Ggplot2 is a common pattern for data visualization that splits graphs into semantic elements like layers and scales. 

A cohort analysis is a very undermined business analytics technique. It is a very effective cost-saving tool that helps the company assess how much they should spend on each customer based on customer lifetime (retention). Moreover, such a tool, like Google cohort analysis, is crucial. Hence, it reflects on the amount of effort that businesses would put in to retain their varied clientele.
