Stage 08 of 08
Growth and Optimization
Measure performance, improve conversion and retention, and run meaningful experiments.
Objective
Build a measurement and experimentation rhythm that steadily improves acquisition, conversion and retention — and tells you when to revisit earlier stages.
Why it matters
Sustainable growth comes from compounding small, well-understood improvements and from keeping the customers you already have. Without reliable measurement, it is impossible to tell real progress from noise.
Important questions
- Which few numbers tell us whether the business is healthier than last month?
- Where is the biggest opportunity: more visitors, better conversion or better retention?
- Which experiments would change a decision if they succeeded?
- Are results changing because of our actions or because of external factors?
- Has anything changed that means we should revisit our positioning or offer?
Practical checklist
- Agree on a small set of core metrics and define each one precisely.
- Set up a regular review: weekly for activity, monthly for outcomes.
- Prioritise experiments by expected impact, confidence and effort.
- Track retention and repeat purchase, not only new customers.
- Document what you learn so knowledge stays with the business.
Deliverables and tools
- Measurement plan
- Business goal → marketing objective → metric → data source → owner.
- Experiment backlog
- Ideas scored by impact, confidence and effort, with results recorded.
Common mistakes
- Tracking many metrics and acting on none.
- Running experiments too small to change a decision.
- Focusing only on acquisition while customers quietly leave.
You are ready to move on when…
- You can explain last month’s results and why they changed.
- There is always a prioritised list of the next experiments.
