Cohort analysis groups customers by when they were acquired and tracks their behavior over time. It's the most powerful tool for understanding retention, repurchase patterns, and whether your marketing is improving over time.
Building Your First Cohort Table
Group customers by acquisition month. Track monthly revenue, retention rate, and cumulative value for each cohort. After 6-12 months of data, patterns emerge that aggregate metrics completely hide.
Reading Retention Curves
Healthy retention curves flatten - the rate of customer loss slows over time as committed customers remain. Unhealthy curves continue declining linearly. Compare curves across channels: does Google Ads retain differently than organic? Does lifecycle email improve retention?
Cohorts by Acquisition Channel
The most actionable cohort analysis segments by source. Customers from content marketing may retain 2x longer than those from paid ads. This data directly informs channel budget allocation.
Improving Cohort Performance
Track whether recent cohorts perform better than older ones. If Month 3 retention is improving quarter-over-quarter, your product and marketing are getting better. If it's declining, something fundamental needs attention.
