Forecast acquisition costs as a promotion ends
Anticipate how pricing, demand, and campaign mix change after a sale.
Keep separate sale and post-sale assumptions
A campaign pays $25 per acquisition during a sale and $38 in ordinary weeks. If the sale audience and offer differ, the first figure should not set the next budget. Use historical periods with a similar price and delivery promise.
Recompute contribution at regular price
After a discount ends, per-order contribution can rise even as conversion falls. If contribution rises from $30 to $45 and CPA from $25 to $38, after-ad contribution per order rises from $5 to $7, but total contribution still depends on volume.
Plan the transition before the cutoff
Schedule ad and landing-page updates together. Check any tracked links and the displayed checkout price. Review spend and mature orders after the transition so residual sale demand is not mistaken for ordinary performance.
