How Longest-dwell ranking works
Ranks by attention — average time on the product page = total dwell ÷ impressions — surfacing considered items people study before deciding.
Longest dwell ranks by average time on the product page — total dwell divided by impressions. Long dwell means shoppers are studying it: a considered purchase. It surfaces the items that hold interest.
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 each product’s total dwell time by its number of impressions to get the average time per view. A product seen by thousands but skimmed in seconds ranks below one that fewer shoppers study for longer — attention, not traffic.
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.
