One of the great benefits of a cohort analysis is that you can compare how time changes customer behavior.
When cohorts are month-based, like in Repeat Customer Insights, you can compare the vertical columns to see how customers behave after e.g. 1 month, 2 months, 6 months.
That'll let you notice changes in revenue, AOV, or overall ordering behavior. When one is much higher or lower than the others, that's a good candidate for investigating deeper.
Use percentages and you can even compare busy to slow periods.
