Cohort Analysis in Adobe Analytics is a powerful method for examining how groups of users behave over time. By segmenting users into cohorts based on shared characteristics during a specific period, you can analyze patterns related to retention, engagement, and conversion. This deep insight helps businesses make informed decisions to enhance user experience and optimize marketing strategies.
What Is Cohort Analysis?
A cohort is a group of users who share a common attribute within a defined time frame, such as the month they first made a purchase or signed up for your service. Cohort Analysis involves studying these groups over subsequent periods to observe changes in behavior. It answers crucial questions like how long users continue to engage with your product after their initial interaction.
Benefits of Using Cohort Analysis
- Understand User Retention: Track how well you retain users over time.
- Evaluate Marketing Campaigns: Measure the long-term effectiveness of acquisition strategies.
- Identify Behavioral Trends: Detect patterns in user engagement and conversion rates.
- Improve Product Development: Gain insights into how updates impact user behavior.
Setting Up Cohort Analysis in Adobe Analytics
1. Access Analysis Workspace
- Log In: Enter your Adobe Experience Cloud credentials to access Adobe Analytics.
- Navigate to Workspace: From the top menu, select Workspace under the Analytics section.
- Create a New Project: Click on Create New Project or open an existing project where you want to perform cohort analysis.
2. Add the Cohort Table Visualization
- Open Visualizations Panel: On the left sidebar, find the Visualizations section.
- Drag and Drop: Drag the Cohort Table visualization into your workspace area.
3. Configure Cohort Settings
a. Define Inclusion Criteria
- Inclusion Dimension: Choose a variable that defines your cohort basis, such as First Time Visits, First Purchases, or custom events.
- Date Range: Select the time frame during which users are included in the cohort (e.g., users who made their first purchase last month).
- Inclusion Metric: Optionally, specify a metric to further refine the cohort (e.g., users who spent over $100).
b. Set Return Criteria
- Return Metric: Specify what action or metric you want to measure over time, such as Visits, Revenue, or Purchase Events.
- Return Criteria: This defines the condition for users to be counted in subsequent periods (e.g., users who return and make a purchase).
c. Choose Granularity
- Time Granularity: Select the interval for your analysis—Daily, Weekly, Monthly, or Quarterly.
- For long-term trends, Monthly or Quarterly might be appropriate.
- For short-term analysis, Daily or Weekly provides more granular insights.
d. Apply Segments and Filters
- Segments: Apply predefined or custom segments to focus on specific user groups, such as Mobile Users or New Customers.
- Filters: Use filters to exclude irrelevant data, ensuring your analysis remains focused.
4. Populate the Cohort Table
- Drag Metrics: From the left sidebar, drag relevant metrics into the cohort table.
- Examples: Retention Rates, Total Revenue, Number of Transactions.
- Adjust Settings: Click on the gear icon to modify settings like Display, Format, and Calculation Methods.
5. Interpret the Cohort Analysis
Reading the Table
- Rows: Each row represents a cohort defined by the inclusion criteria and time frame.
- Columns: Columns correspond to subsequent time periods based on the chosen granularity.
- Cells: Each cell shows the metric value for that cohort during that time period.
Analyzing Data
- Retention Rates: Observe how the percentage of active users declines or stabilizes over time.
- Engagement Metrics: Look for increases or decreases in metrics like revenue or session duration.
- Compare Cohorts: Identify differences between cohorts to understand the impact of changes in marketing, product features, or external factors.
6. Visualize the Data
- Heatmaps: Use color gradients to highlight high and low values, making patterns more apparent.
- Line Charts: Convert data into line graphs to visualize trends over time.
- Annotations: Add notes to mark significant events like campaign launches or website updates.
Practical Examples
Example 1: Measuring User Retention After Sign-Up
- Inclusion Criteria: Users who registered on your site each week.
- Return Criteria: Users who log in again.
- Granularity: Weekly analysis over three months.
- Insight: Determine the effectiveness of onboarding processes and identify when users are most likely to drop off.
Example 2: Evaluating a Marketing Campaign
- Inclusion Criteria: Users who made a purchase during a promotional period.
- Return Criteria: Subsequent purchases made.
- Granularity: Monthly over six months.
- Insight: Assess the long-term value of customers acquired through the campaign versus regular customers.
Advanced Tips for Cohort Analysis
Use Calculated Metrics
- Create Custom Metrics: Combine standard metrics to develop more meaningful indicators (e.g., Average Revenue per User).
- Retention Rate Calculations: Define retention as the percentage of users who return, providing a normalized view across cohorts of different sizes.
Incorporate Segmentation
- Demographics: Segment cohorts by age, location, or device to uncover specific trends.
- Behavioral Segments: Group users based on actions like High Engagement or Cart Abandoners.
Compare Multiple Cohorts
- Parallel Analysis: Set up multiple cohort tables side by side to compare different user groups.
- Identify Outliers: Spot cohorts that significantly outperform or underperform others, indicating potential areas for investigation.
Best Practices
Maintain Consistency
- Standard Definitions: Ensure that inclusion and return criteria are consistently applied across analyses.
- Time Frames: Use consistent date ranges and granularities when comparing cohorts.
Start Simple
- Focus on Key Metrics: Begin with essential metrics like Retention Rate or Revenue before adding complexity.
- Avoid Over-Segmentation: Too many segments can make data unwieldy and harder to interpret.
Validate Data Quality
- Check for Anomalies: Look for data spikes or drops that might indicate tracking issues.
- Ensure Statistical Significance: Larger cohorts provide more reliable insights; be cautious with small sample sizes.
Iterate and Refine
- Regular Reviews: Analyze cohort data periodically to monitor trends and the impact of any changes made.
- Adjust Strategies: Use insights gained to modify marketing tactics, improve user experience, or adjust product features.
Common Challenges and Solutions
Interpreting Complex Data
- Challenge: Large datasets can be overwhelming.
- Solution: Utilize visualization tools like heatmaps and charts to make patterns more digestible.
Attribution of Changes
- Challenge: Difficult to pinpoint what caused changes in cohort behavior.
- Solution: Correlate cohort data with known events or changes, such as marketing campaigns or site updates.
Data Accuracy
- Challenge: Inaccurate data can lead to incorrect conclusions.
- Solution: Regularly audit your data collection methods and ensure tracking codes are correctly implemented.
