ACTIONABLE INSIGHTS
Clear, data-driven recommendations to improve your marketing efficiency and maximize ROI across all channels.
KEY METRICS
Essential metrics to understand your marketing efficiency
SPEND CHANGE
ΔSpend = Spend(n) - Spend(n-1)
Difference in budget between today and yesterday
REVENUE CHANGE
ΔRevenue = Revenue(n) - Revenue(n-1)
Difference in revenue between today and yesterday
MARGINAL ROAS
Marginal ROAS = ΔRevenue / ΔSpend
Return on each additional dollar spent
UNDERSTANDING MARGINAL ROAS
The metric that reveals incremental value and helps identify the point of diminishing returns
WHAT IS DIMINISHING RETURN?
The first point where Marginal ROAS drops below your target ROAS or falls dramatically.
STRATEGIC ACTIONS:
- • Don't scale this channel/ad set further
- • Move excess budget to campaigns with better Marginal ROAS
- • Check if efficiency drop is due to audience fatigue, creative fatigue, or broad targeting
NEGATIVE MARGINAL ROAS
When ΔRevenue < 0 and ΔSpend > 0, you get negative Marginal ROAS.
THIS MEANS:
You spent more but generated less revenue than the previous day. Each additional dollar brought a loss in performance (not financial loss).
PRACTICAL EXAMPLE
ΔRevenue: $1,098 (more revenue)
ΔSpend: -$121.69 (less spend)
Marginal ROAS: -9.02
You reduced budget but increased revenue - previous spending was inefficient!
MONITORING BEST PRACTICES
Track Marginal ROAS daily for each channel
Monitor aggregated media mix performance
If 3 consecutive days show negative/below-target results, stop scaling
Very high Marginal ROAS may indicate previous overspend
WARNING SIGNS
Red flags indicating you're hitting diminishing returns
NEGATIVE MARGINAL ROAS
Stop scaling immediately. Previous spend was inefficient and not delivering value.
BELOW TARGET ROAS
You've reached the point of diminishing returns. Consider redistributing budget to better performing channels.
VERY HIGH MARGINAL ROAS
May indicate previous day had significant overspend that didn't deliver proportional value.
STABLE POSITIVE
Good incremental performance. Continue monitoring and consider gradual, measured scaling.
