Few systems attract as many myths as the Amazon algorithm. Some claim you have to trick it; others surrender to it like a black box. The truth is in between: the algorithm fairly consistently rewards what it’s meant to — books that people find, buy and like.
Sales are the strongest signal
Nothing ranks a book faster than sales, especially in a short window. A concentrated launch that bundles many purchases into a few days sends a strong signal — far stronger than the same volume spread over weeks. That’s why the choreography of the first week matters so much.
Sales velocity — purchases per time, not just volume
Conversion — how many go from click to purchase
Relevance — do keywords match the search query?
Reviews — count and recency, not just average
The algorithm isn’t an opponent to outwit. It’s a mirror of what readers do.
Keywords are discoverability
The best book stays invisible if it matches no search query. Keywords and categories are the bridge between what people search and what you offer. They should hit real search terms — not what you’d like, but what’s actually typed.
No trick replaces quality
All optimization fizzles if the book doesn’t deliver what the cover promises. High conversion and good reviews come only from satisfaction. The algorithm amplifies what works — it doesn’t create it. To rank sustainably, optimize the book first and visibility second, never the other way around.
