The Engagement

Performance-based-Tier engagement with cost-per-purchase tracked as the primary diagnostic KPI. CPP improvement is the case for what the Viestri system produces when given time to compound. Month one is execution. Month two is iteration. Month three onward is where CPP starts to fall as creative learnings stack and audience structure tightens.

Operating cadence
Why CPP improvement compounds. The intelligence layer feeds back into itself. Each month's top creative becomes the template for next month's brief. Each month's best converter audience becomes the base for next month's lookalike. The system is not magic. It is documented iteration on top of documented baselines.
