Without a framework, channel budgets ratchet up during good weeks and rarely ratchet back down. The result is a portfolio of half-saturated channels with mediocre payback. A clear framework makes the reallocation decisions explicit and reversible.
The four quadrants
Scale aggressively: payback under target AND volume increasing AND CAC stable. Add 30–50% budget per cycle. Watch for the first sign of CAC drift.
Hold spend: payback at target but CAC starting to climb. Don’t cut yet — diagnose the cause (creative fatigue, audience saturation, seasonal). Often a creative refresh moves the channel back into the scale quadrant.
Cap: payback above target for one month. Hold spend flat, run a structured creative or audience test, and re-evaluate next cycle.
Cut: payback above target for two consecutive months without a clear hypothesis for fixing it. Move spend to a working channel.
- Scale: payback < target, volume up, CAC stable → +30–50% budget
- Hold: payback at target, CAC climbing → flat spend, diagnose
- Cap: payback > target, 1 month → flat spend, run a test
- Cut: payback > target, 2 months → reallocate budget
Reset cadence
Run the framework on a monthly cadence. Reset the targets and rules quarterly so they reflect current ARPA, churn, and capital constraints. Document the framework so new team members aren’t starting over.
The most common mistake is ratcheting up too fast on a single hot month. Two consecutive hot months at scale is the threshold; one is variance.
What to watch for.
- Scaling on a single hot month
One hot month can be variance. Require two consecutive months at the scaling thresholds.
- Cutting before diagnosing
A spike in CAC is often fixable with creative or audience changes. Diagnose before you reallocate.
- Forgetting to refresh targets
Payback targets shift with company ARPA and churn. Reset quarterly.
Recap.
- Scale aggressively when payback is under target AND volume is increasing without CAC drift
- Hold spend when payback hits target but CAC starts climbing — diagnose creative or audience fatigue first
- Cap or cut when CAC payback exceeds the threshold for two consecutive months
- Reset the decision quarterly — channels rotate in and out of efficiency over time
- Document the rule so handoffs and new hires don’t reset the framework
