How this ranking is built — and what it does not claim

Ranked from Amazon’s own customer-review ordering and Best Sellers Rank. Amazon does not publish star ratings or review text through its Creators API, so none are shown.

Each product's customer standing score blends these inputs:

Customer-review ordering (35%) — where the product falls in Amazon's own AvgCustomerReviews result ranking.
Best Sellers Rank (30%) — how many units actually move, on a log scale.
Catalogue relevance (25%) — how central the product is to the search a keeper would run.
Live discount (10%) — current price against list price.

Products that surface in both Amazon's review-ranked and relevance-ranked results earn a corroboration bonus — that overlap is the strongest signal available that a well-regarded product is also the right one for the job.

What we don't do: we never print a star rating, a review count, or a reviewer quote we don't actually hold. Where Amazon shows us no rating for a product, we rank it on the signals above rather than invent a number.
