How Highest-CTR ranking works
Ranks by click-through rate = clicks ÷ impressions, raw with no statistical smoothing, so an efficient low-traffic product can beat a more-viewed one.
Highest CTR ranks by click-through rate — clicks ÷ impressions — a raw ratio with no smoothing. It rewards efficiency, not traffic, so a product few people see but many click can lead. Zero-view products are dropped.
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 clicks by its impressions over the window. There’s no Bayesian/Wilson smoothing — it’s the literal rate — with a single guard that drops products with zero views. The highest rate takes #1, even if it’s seen the least.
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.
