When to use it
Use it for weekly or monthly reallocations, scale-up reviews, and saturation checks. Response curves are more useful when each channel has enough historical spend and outcome variation.
What it estimates
The tool compares estimated incremental outcomes near current spend. A channel with strong average efficiency can rank lower when it is near saturation, while a moderate channel can rank higher when headroom remains. It is a historical simulation, not a guarantee.
How to act
Apply recommendations in small steps, then compare actual CPA or ROAS with the estimated range. Check cannibalization before increasing a suspect channel, and treat sparse new channels as an experiment budget rather than a model-led scale decision.
Frequently asked questions
Can I apply the recommended split as-is?
Applying the full move at once is not recommended. It is a simulation from historical observations, so shift in small steps and compare actuals against the estimated range.
Why not give everything to the best average-efficiency channel?
Because the decision uses marginal efficiency. A saturated channel produces a worse next unit than its average suggests, which lowers its priority.
Can it plan budgets far above anything observed?
Reliability drops sharply outside the observed spend range, so the tool constrains recommendations to stay within each channel's observed maximum spend.
