What gets counted
Every product link here carries this site's tracking ID. Amazon reports back, for that ID alone, which products were ordered and what fee each order paid. Those reports are the only numbers the ranking reads.
For each pick the site works out one figure: the fee it earns per reader click. A pick that many readers buy after clicking scores high. A pick readers click and then leave scores low and sinks.
orders per click = (its orders + 50 x the site's rate) / (its clicks + 50) fee per click = orders per click x its fee per item
The 50 keeps a lucky start from jumping the line. A pick with two clicks and one order is held near the site's average until its own clicks outweigh that.
New picks wait
A pick with no orders yet has no number. It sits under the numbered picks and is marked "Not ranked yet". It earns a place when readers have bought it.
What this site does not do
It has not tested the products. It shows no prices, scores or review totals from Amazon, because those change by the hour. Read the product page for the current details before you buy.
The photos show the kind of product, unbranded. They are illustrations and never the exact item sold.
How the site earns
Through those same orders. When you buy through a link here, Amazon pays this site a fee and your price stays the same. The privacy and disclosure page has the rest.
