Feed net revenue and refund rates back into bidding so auction decisions value likely contribution, not only clicks. Pause high-CPA keywords that attract price shoppers with poor collection rates, and expand profitable long-tail intents where competitors underbid because their metrics ignore service fulfillment constraints.
Use modeled audiences seeded with customers who completed payment and never charged back. Pair creative that sets accurate expectations with landing flows that qualify, schedule, and capture consent. This formula reduces cancellations, increases repeat bookings, and unlocks higher budgets without inviting fraud or accidental engagement spikes.
Test localized flights with geographic holdouts and card-linked offer panels to estimate uplift grounded in transactions. Combine store visit signals, inbound call spikes, and payment velocity to confirm causality. When uplift persists after saturation, scale regionally; if it fades quickly, rework message, placement, or timing before expanding.
