What is cohort analysis, and why does it matter more than a single repeat-rate number?
The short answer
Cohort analysis groups customers by when they first bought and tracks how each group behaves over time - so instead of one blended '35% repeat rate,' you see that your January cohort retained 42% at month 3 while April retained only 28%. That gap is the actual signal: it tells you a creative, offer or supply-chain change hurt retention, which a single average number will always hide. Build the table by acquisition month and months-since-first-order before you trust any repeat-rate headline.
