How Most-clicked ranking works
Ranks by pull — the sum of clicks through to the product page in the window — the first deliberate step a shopper takes past a grid tile.
Most clicked to PDP ranks by the sum of clicks through to the product page in the window. A click is the first thing a shopper chooses to do — it says the tile earned the trip. Unlike CTR, this is volume, not efficiency: a widely-clicked product leads even if plenty of people scrolled past it. Products with no clicks in the window 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

The engine sums each product’s product-page clicks from the storefront pixel over the window and sorts descending. It sits one step past Most impressions and one step short of Most added to cart — good when you want the tiles shoppers actually open at the front, without letting a low-traffic product with a freak rate jump the queue. Engagement signals measure in whole days, so an hours-based window counts as one day, and a Period or Snapshot window falls back to the last 30 days.
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 have clicks than your Max products cap allows, the leftover slots are filled from the collection’s current order, below everything that was actually clicked.
