Amazon has introduced a subtle but notable change to its product review system: customers can no longer leave product ratings without a written comment on certain screens. While this may seem like a small tweak, it could lead to a shift in how ratings and reviews are distributed across the platform. Historically, customers who leave ratings without comments tend to be more positive, whereas those who take the time to write reviews often skew more critical. This change could result in slightly lower overall average ratings, but it may also provide brands with richer, more detailed feedback.
Amazon has not publicly addressed this change, and their FAQ avoids referencing it, as seen here:
A snippet from Amazon FAQs, still implying that adding review text is optional:
How Amazon calculate overall star ratings:
“Amazon calculates a product's star rating using machine-learned models instead of a simple average. These models consider factors such as how recent the rating or review is and verified purchase status. They use multiple criteria that establish the authenticity of the feedback. The system continues to learn and improve over time. We do not consider customer ratings without an Amazon Verified Purchase status in a product's overall star rating until a customer adds more details in the form of text, image, or video.”
As this policy rolls out, it’s unclear whether it applies to all products or just a subset. Yogi will continue tracking these changes and analyzing their impact on consumer behavior, product rankings, and sentiment trends.
