Campaign Leadership, Activation & Governance

Lead activation and optimization across Amazon Ads (Search & DSP), Walmart Connect, Instacart Ads, Criteo, Uber Ads, DoorDash Ads, and Loblaws (MediaAisle).
Own end-to-end campaign governance: creative requirements and QA, tracking/tagging (where applicable), flighting, budget allocations, pacing, keyword/bid/audience optimization, and ongoing brand safety + compliance checks.
Establish clear performance guardrails (KPIs, learning agenda, optimization cadence) and ensure timely escalation of risks (inventory/OOS, pricing gaps, creative fatigue, tracking/reporting issues).

Strategy & Planning

Translate client briefs into channel strategy and full-funnel plans: audience frameworks, targeting approach, measurement plan, and a structured testing roadmap (A/B tests, incrementality/lift, geo tests, creative tests).
Partner with commerce/retail readiness stakeholders to improve conversion and efficiency: catalog hygiene, PDP content, reviews/ratings, pricing and promo strategy, inventory checks, and OOS suppression.
Build and maintain media plans and forecasts (scenario planning, and sufficiency planning where needed).

Reporting & Insights

Own cross-platform reporting and insights across Amazon Search/DSP/AMC, Walmart, Instacart, Criteo, Loblaws (MediaAisle) and other platform UIs; ensure clean data, consistent definitions, and executive-ready reports.
Turn performance into a clear narrative: what happened, why it happened, what we learned, and what we’re doing next with actionable recommendations and quantified impact.
Use AMC (where available) to support deeper insights (path-to-purchase, overlap, audience performance, incrementality signals) and improve targeting and measurement.

Client-Facing Ownership
