The details · Amazon
Every Amazon algorithm guide is an educated guess, because Amazon keeps the rules private.

“Amazon does not disclose information or release official documentation around search/discovery algorithms.”
What I found
An Amazon community manager: "Amazon does not disclose information or release official documentation around search/discovery algorithms." Six guides I compared disagree on what matters most (four lean on sales velocity, two on conversion), measure different things, and none showed their data on the page I read.
So do this
Read guides for ideas, not rules. Nobody is holding a formula you're missing.
Keep in mind
That forum thread is about product search in general. I found nothing from Amazon saying books work differently.
