Amazon Marketing

A10 Algorithm

A10 Algorithm is Amazon's search ranking algorithm (successor to A9). It determines which products appear for which search queries + in what order.

Key ranking signals (per public Amazon documentation + observed behaviour):

  • Sales velocity for the query
  • Conversion rate from search to purchase
  • Customer review quality + recency
  • Title + bullets + backend keyword relevance
  • Listing quality + completeness
  • Sponsored Ads click-through (modest signal)

A10 changes constantly; the operational discipline is to optimise for current ranked behaviour (regular listing audits + backend keyword refreshes) rather than chase rumoured changes. See our Amazon Listing Optimisation for the practical playbook.
