## Why measurement

Communities without measurement drift into vanity metrics (member count). Mature programs measure depth (engagement), breadth (growth), value (ROI). Without measurement, communities lose strategic justification.

## Engagement metrics

- DAU, WAU, MAU.
- Active member rate (active / total).
- Posts per active member.
- Reply rate.
- Member-to-member connections.
- Sentiment per post.
- Returning member rate.
- New member onboarding completion.

## Growth metrics

- New members per period.
- Member growth rate.
- Source of new members.
- Member retention (30, 60, 90 days).
- Member churn.
- Re-engaged lapsed members.

## Value metrics

- Member LTV vs non-member.
- NPS difference.
- Retention difference.
- Expansion difference.
- Referrals from members.
- Reviews from members.
- Case studies / speakers from members.
- Product feedback contributions.

## Sentiment

- Member NPS.
- Quarterly member surveys.

- Promoter activation.

## Community ROI

- Cost: platform + community manager + tooling + events.
