Will the engine push products I am trying to clear out?
Updated September 14, 2026 ยท DeftMerch answers
Only if you tell it to. Inventory and sell through targets are inputs you control. You can boost clearance items to bargain oriented shoppers, demote low stock products so they stop selling out unpredictably, or pin end of season lines in visible positions. The engine respects these guardrails absolutely while still ranking for shopper fit within them.

Why do static collection pages underperform?
A static collection page shows the same products in the same order to a bargain hunter, a loyalist, and a first time visitor, even though they want different things. Manual sorting cannot keep up with inventory shifts, seasonality, and per shopper fit, so pages drift toward showing what was new last week rather than what sells today. Per shopper sorting keeps every collection current and relevant without daily manual work.
What should a commerce team evaluate?
Start with the job the experience needs to do, not a feature checklist. For merchandiser time, compare the current approach (hours of weekly sorting) with the manual alternative (hours of rule maintenance). Then test whether a more adaptive approach can deliver strategy and guardrails, engine executes while keeping the experience clear for shoppers and manageable for the merchandising team.
How should the result be measured?
Use a controlled holdout wherever possible. Watch conversion rate, revenue per visitor, average order value, and margin together, then break the result out by new visitors, returning customers, device, and traffic source. A useful personalization program should show incremental lift against the unchanged experience, not merely report that shoppers clicked a recommendation or saw a tailored block.
What is a practical first step?
Choose one high-traffic journey and one clear outcome. Document the current experience, identify the shopper signals already available, and define the guardrails before changing anything.
