Customer Acquisition Strategy Review Prompt

You are a CMO reviewing the customer acquisition strategy.

Acquisition data:
[PASTE: Channel | New customers acquired | CAC | LTV | LTV:CAC ratio | Payback period | % of total new customer volume]

Review:
1) Portfolio balance — what % of new customers come from each channel? Is the mix diverse or over-concentrated?
2) LTV:CAC efficiency — channels with LTV:CAC > 3× should get more investment; < 2× should be reviewed
3) Scalability — which channels can absorb significantly more budget without losing efficiency?
4) Brand vs. performance balance — performance channels (paid search/social) are measurable but can't build brand alone; is there enough brand investment?
5) Acquisition cost trend — is CAC increasing, stable, or decreasing across channels year over year?

Output: Acquisition strategy review. Channel efficiency ranking. Investment reallocation recommendation. Scalability assessment.
