All together now – Cohort analysis explained

Summary

Cohort analysis is a powerful data technique that divides users into groups sharing common characteristics like acquisition date or behavior, allowing marketers to compare performance over time. Unlike traditional metrics, it filters noise to reveal genuine trends—such as which campaigns drive the most revenue or when users churn. It helps optimize ad spend by identifying underperforming channels, fight fraud by spotting suspicious patterns, improve retention by smoothing user journeys, and tailor offerings based on behavior.

Common models include UA (acquisition) and behavioral cohorts. Practical uses include assessing multi-regional campaigns, comparing media source ROI, and analyzing in-app events. Key steps include defining questions, metrics, and specific cohorts before evaluating results.
