Cohort Analysis for Client Reporting

Source: Raaz (c.2023) Web Analytics Blueprint

Use when

• Builds time-based and behaviour-based user cohorts in GA4, tracks retention and lifetime value by cohort, and translates cohort data into client-language statements that demonstrate campaign durability — not just reach. Invoke when a client asks which campaigns produce repeat customers, when aggregate metrics are masking poor retention, or when preparing a report that must show long-term campaign value.
• Use this skill when it is the closest match to the requested deliverable or workflow.

Do not use when

• Do not use this skill for graphic design, video production, software development, or legal advice beyond the repository's stated scope.
• Do not use it when another skill in this repository is clearly more specific to the requested deliverable.

Workflow

1. Collect the required inputs or source material before drafting, unless this skill explicitly generates the intake itself.
2. Follow the section order and decision rules in this SKILL.md; do not skip mandatory steps or required fields.
3. Review the draft against the quality criteria, then deliver the final output in markdown unless the skill specifies another format.
