A practical explanation of how Amazon's search ranking actually works, and what that means for listing strategy.
Unlike Google's algorithm, A9 weighs sales velocity and conversion performance heavily alongside keyword relevance — a listing that converts well tends to rank better, creating a compounding effect.
Because conversion performance matters so much, keyword-stuffed listings that hurt readability and conversion often rank worse than well-written listings with slightly less keyword density.
Optimizing for A9 means optimizing for actual customer conversion, not just keyword placement — the two goals are more aligned on Amazon than on some other search platforms.
There's ongoing debate in the seller community about the exact relationship, but sales velocity driven by PPC can indirectly support organic ranking through the sales-performance signals A9 weighs.
Amazon doesn't publish a fixed schedule, but the algorithm evolves continuously — staying current on listing best practices matters more than trying to reverse-engineer specific updates.
