What Is Cohort Analysis?
Grouping users by shared acquisition window and tracking their behavior forward month over month. In analytics work, this term is one of the building blocks operators use every day, so it pays to have a clean, one-line mental model.
Where you'll see it
You'll usually meet "Cohort Analysis" inside analytics reporting, briefs, or platform UIs. When it appears, ask two questions: what exact input is it measuring, and against what benchmark. That's the whole job of understanding a term like this.
Why it matters
Tracking is the fact base every optimisation depends on. If this concept is fuzzy, every downstream number — CPA, ROAS, CVR — inherits the same fuzziness.
Common mistakes
- 1.Treating "Cohort Analysis" as self-explanatory. Different teams and platforms define it slightly differently — always confirm the exact input before you argue about the output.
- 2.Comparing values across platforms without checking definitions. Meta, Google, LinkedIn, and TikTok each measure adjacent-but-different things under similar names.
- 3.Optimising to the term in isolation. Every metric or lever in this glossary needs at least one guardrail metric to stay honest.
