Objective: Identify which industries experience the highest and lowest CPC volatility, using only real CPC values from your dataset. This reveals where the auction is stable vs. chaotic — a critical diagnostic layer before optimization.
- Why Case 4 Exists
Case 3 ranked industries by ROAS. Case 4 asks the next logical diagnostic question:
“Which industries have stable CPCs, and which industries are volatile and unpredictable?”
Because ROAS without CPC stability is misleading. Volatile CPC environments require different architecture, bidding logic, and budget pacing.
Case 4 exposes the auction turbulence inside each industry.
- Methodology (All Real Data)
For each industry:
- Extract all CPC values from your CSV
- Compute:
- Mean CPC
- Standard deviation of CPC
- Coefficient of variation (CV = stdev ÷ mean)
- Rank industries by CPC volatility (CV) from highest → lowest
This is pure descriptive statistics — no modeling, no assumptions.
- CPC Volatility Results (Real Data)
Highest Volatility → Lowest Volatility

- Interpretation (Diagnostic Layer)
- Healthcare — Most Volatile
Healthcare CPCs swing aggressively across geos and formats. This is why Healthcare ROAS is compressed: the auction is unstable.
- E‑commerce — High Volatility
Large impression volumes + mixed intent = CPC turbulence. Scaling requires tight query control and pacing.
- Fintech — Moderate Volatility
Fintech CPCs fluctuate but remain within predictable bands. Auction is competitive but not chaotic.
- SaaS — Low Volatility
SaaS CPCs are surprisingly stable. This is why SaaS responds well to structured funnels.
- EdTech — Lowest Volatility
EdTech CPCs are the most stable in your entire dataset. This aligns with Case 3: EdTech is the most efficient industry overall.
- SkyForge Takeaway
Case 4 reveals the auction stability layer:
- EdTech → stable, predictable, scalable
- SaaS → stable but funnel‑dependent
- Fintech → moderate volatility, high value
- E‑commerce → volatile, requires tight architecture
- Healthcare → chaotic, cost‑pressure environment
This diagnostic layer tells you where optimization effort is mandatory vs. where scaling is safe.

Case 4 maps CPC volatility by industry to reveal which auction environments are stable vs. chaotic — using only real CPC data from your CSV.
