How Most-profitable ranking works
Ranks by the profit margin you set per product — a pure catalog attribute, no behaviour and no time window — so your highest-margin items lead.
Most profitable ranks by a catalog attribute: the profit margin you set on each product. Unlike every behavioural signal, it ignores sales, views and time entirely — it simply orders your collection so the items that make you the most money per sale come first. Products you haven’t set a margin on can’t be ranked and are left out.
1. The collection, unranked

A normal collection page. The order is whatever the catalog lists — the best performers could be buried on the second row where few shoppers scroll.
2. The ranking engine scores it

There’s no data pipeline behind this one — the engine reads each product’s margin percent straight from its metadata and sorts descending, skipping any product with no margin set. Nothing rolls in or out over time, and there’s no window picker to set; change a product’s margin and its rank updates on the collection’s next sync. It’s the signal for merchandising by profitability.
3. The front row gets discovered

The strongest products now fill the front row — the slots that get the most views and clicks. That’s the payoff: ranking turns your best products into the ones shoppers see first. If fewer products carry a margin than your Max products cap allows, the leftover slots are filled from the collection’s current order, below every product with a real margin.
