Amazon says in its Understanding Customer Reviews and Ratings help page that reviews and ratings are subject to submission requirements and review checks. Amazon also says a product’s overall star rating is based on machine-learned models instead of a simple average.
What submission requirements does Amazon mention?
Amazon says on the help page that only customers who have spent at least $50 on Amazon in the last 12 months can submit ratings and reviews.
Amazon also says it checks reviews before they are posted to confirm they meet its community standards.
How does Amazon say it calculates overall star ratings?
Amazon says in the same page that it uses machine-learned models rather than a simple average to calculate a product’s overall star rating.
Amazon says those models consider factors such as how recent a rating or review is and whether it comes from an Amazon Verified Purchase.
What does Amazon say about suspicious reviews?
Amazon says on the ratings explainer that automated and human checks stop millions of suspicious reviews.
The same page also says Amazon takes legal action against groups that pay customers to post fake reviews.
How does Amazon position reviews and ratings inside the shopping experience?
Amazon’s ratings explainer presents reviews and ratings as a system that combines submission rules, policy checks, and ranking logic to help customers evaluate products.
That is a broader description than “five stars from customers.” Amazon is describing a moderated trust system rather than a raw comment feed.
