How New-arrivals ranking works
Ranks by go-live date, newest first — and only products that went live inside the window qualify, so the collection stays fresh automatically.
New arrivals ranks by go-live date, newest first. It also uses the window as a filter: only products that went live within the window appear at all, so as items age past the window they drop out and the collection refreshes itself.
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

The engine sorts by each product’s live date, most-recent first, and keeps only those whose live date falls inside the window. There’s no behaviour involved — it’s purely “what’s new” — and the window doubles as an auto-expiry so yesterday’s launches don’t linger.
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.
