FAQ
What is the difference between paid CAC and blended CAC?
Paid CAC only includes media spend, while blended CAC adds team and tooling costs so you see true acquisition efficiency.
Why does blended CAC matter for scaling?
Blended CAC shows whether your growth model still works after all acquisition overhead, not just ad platform spend.
How do I lower CAC without hurting growth?
Improve conversion rate, increase repeat purchase rate, and tighten targeting before simply increasing bids.
