Founders love ROAS—but relying on a single metric is the quickest way to make poor marketing decisions.
Here are 10 metrics founders should watch to truly understand performance:
1. CAC (Customer Acquisition Cost)
Your real cost per customer—not just per click.
2. Conversion Rate
How efficient your funnel is.
3. MER (Marketing Efficiency Ratio)
Total revenue / total ad spend = big-picture profitability.
4. LTV (Lifetime Value)
Your growth depends more on LTV than first-time purchases.
5. AOV (Average Order Value)
Small improvements create massive revenue jumps.
6. Frequency
Too low = no impact.
Too high = ad fatigue.
7. CTR (Click-Through Rate)
A reflection of creative quality.
8. CPM
Signals competition and seasonality shifts.
9. Returning Customer Rate
Retention is the new acquisition.
10. Creative-to-Conversion Lag
How long it takes for new creatives to start performing.
Final Thought
Modern marketing is data-driven, but not data-drowning.
Tracking these 10 metrics gives founders clarity, focus, and predictable growth.
