Amazon
Priced to win the Buy Box, not to win the race down
Titles, bullets and images built to convert, and a pricing position argued against margin rather than against whoever discounted last.
Listing work is search work: keyword density optimised across Amazon and Walmart search at a steady weekly cadence, with titles, bullets and imagery written for the buyer rather than for the crawler.
Price is monitored daily against competitors and against the Buy Box, but the decision is always taken against contribution. Matching a price you cannot afford to hold wins the box and loses the month.
