How Customer-favorites ranking works
Ranks by loyalty — the share of buyers who came back and ordered it in a separate order over the last year, so genuine repeat-worthy products lead.
Customer favorites ranks by loyalty: the share of a product’s buyers who ordered it again in a separate order, measured over the last 365 days no matter what window the collection is set to. It rewards products people come back for — not one-time impulse buys or a single big basket. A product needs at least 5 buyers to qualify.
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 divides repeat buyers (customers with 2+ distinct orders of the product) by unique buyers. Two units in one order don’t count as repeat — it has to be a genuine comeback. Products with fewer than 5 buyers are excluded so a tiny sample can’t fluke to the top, and so are products nobody has come back for at all, since a repeat rate of zero is nothing to rank. There’s no window picker on this one: the year-long lookback is fixed.
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 qualify than your Max products cap allows, the leftover slots are filled from the collection’s current order, below every product with a real repeat rate.
