Rebuilt the acquisition mix and cut blended CAC by 41%
The bottleneck. Spend was concentrated in one channel with duplicated conversion events, so profitability could not be read at product level.
What we changed
- Rebuilt GA4 and server-side events with a single source of truth for revenue.
- Split campaigns by margin tier instead of catalogue structure.
- Rewrote the top eight product templates around objection handling and delivery proof.
