Open with the conversion chain, not the media plan. Define the path: inventory query, available result, product selected, reservation, purchase, pickup completed and pickup value. Name who owns each step, including the retail team that keeps the transaction, customer relationship and fulfillment.
Set the primary KPI as incremental contribution from completed pickups. Rule out clicks, platform-attributed purchases and platform ROAS as the headline measure, and state that decision in the plan so it withstands later pressure to report dashboard numbers.
Commit to a holdout design before spending. Maguire’s model used 24 matched geographic clusters and 6 holdouts across 16 weeks. The aim is a measured counterfactual, not an attribution argument after the fact.
Pre-commit allocation thresholds, then hold channels to them. In the simulation, YouTube reported strong attributed revenue but didn’t clear the incremental contribution threshold, while Pinterest and Reddit scaled further than expected. Specify in advance what a channel must clear to keep its budget.
Reconcile platform reporting against holdout-measured lift. In the simulated portfolio, Maguire reports that platform reporting overstated causal completed pickups by roughly 1.94x. The plan needs one method for deciding which number the team will act on.
Brief creative around saved time and local certainty, not the technology. Test propositions such as one store, whole list; ask, confirm, reserve; and avoid a wasted trip. Generic shop-with-AI messaging ran weaker in the simulation.
Spell out the operational dependencies: inventory data quality, store execution, offline conversion tracking, and contribution margin. These determine whether the campaign is measurable, so include them in the plan rather than leaving them for a later integration project.
Deliver a recommendation memo covering channel mix, creative test plan, measurement specification, and operational prerequisites, with a first-test budget and a decision date for scaling. Ask Maguire to supply real campaign reporting and engagement terms; the published figures are hypothetical.
