Budget and Bidding
- Establish objective, conversion value, gross margin, cash constraints, sales capacity, attribution uncertainty, seasonality, and platform minimum evidence.
- Normalize spend and outcomes to comparable windows and definitions.
- Calculate break-even boundaries and show formulas, inputs, uncertainty, and sensitivity cases.
- Distinguish committed baseline, controlled experiments, and reserve capacity.
- Compare hold, reallocate, scale, reduce, or experiment options using marginal evidence rather than blended averages alone.
- Return a decision-complete plan with platform/campaign amount, timing, owner, guardrails, success measure, and rollback trigger.
Rules such as 70/20/10, fixed CPA multiples, fixed budget-to-CPA ratios, and fixed percentage scaling are optional heuristics, never universal authorization.
