Cohort

A group of visitors defined by something they share, like the week they first showed up.

What it means

A cohort is a group of users bucketed by a shared starting point — most often the week or month they first visited — tracked afterward to see how their behavior changes over time.

Why it matters

Cohort analysis answers a different question than a simple trend line: not just 'is traffic up,' but 'are the people who found us in March still coming back in June.'

Can datanephew build a cohort view for me?

Ask it to compare how visitors from a specific period behaved afterward — it can pull that from Analytics without you setting up a custom report.

Is cohort analysis only useful for subscription businesses?

No — any business that cares about repeat visits or repeat purchases can use it, even a once-a-year retailer looking at seasonal return patterns.
