Online retail has more moving parts than most service businesses. Inventory limits what you can promote, shipping thresholds shape basket size, and returns quietly erase revenue that the ad platforms already counted. A good plan treats these as marketing inputs rather than operations trivia.
Merchandising and offer design
Which bundles lift average order value without cutting margin, when free shipping thresholds should move, and how seasonal drops or restocks become reasons to email rather than reasons to discount. These choices often do more than a new campaign.
Measurement you can trust
Privacy changes weakened pixel data, so the plan sets up server side events where possible, a consistent naming scheme for campaigns and a simple view of blended acquisition efficiency across all paid channels. The goal is fewer arguments about which report is right.
Retention architecture
Welcome series, product view and cart recovery, post purchase education, review requests to your customers, and win-back timing that matches how long your product actually lasts. Each flow gets a job and a metric.
