What Influences the A9 Amazon Ranking Algorithm?

  1. Conversion Rate* – These are ranking factors that Amazon found to have a statistically relevant effect on conversion rates. Examples of conversion rate factors include customer reviews, quality of images and pricing.

  2. Relevancy – Remember the first step in the A9 Amazon Ranking algorithm? They gather the results, and then they decide how to list them. Relevancy factors tell A9 when to consider your product page for a given search term. Relevancy factors include your title and product description.

  3. Customer Satisfaction – How do you make the most money from a single customer? Make them so happy that they keep coming back. Amazon knows that the secret to max RPC lies in customer retention. It’s a lot harder to get someone to spend $100 once than $10 ten times. Customer Retention ranking factors include seller feedback and Order Defect Rate.
