Amazon tests new rating system

 

Stars are very often used in online marketplaces’ product rating systems. The more stars, the higher the cumulative rating. However, Amazon tested a rating system where instead of the usual five, only one star would be displayed.

 

 

A five-star rating system

Rating systems are ever-present features of almost any online marketplace. No wonder: they’re perfect for translating the old word-of-mouth type of customer feedback to the digital age. The aggregated experience of previous buyers is a great basis for new customers to decide if the product or service is worth their time and money.

 

Amazon uses a very easy-to-understand rating system. When viewing a product page, shoppers can quickly spot the outline of five golden stars and a number right below the name of the product. This data is the aggregation of all customer reviews.

 

When a shopper buys a product, they have the option to place a review. On a scale of 1-5, customers can choose how satisfied they are with their purchase, with 1 being the lowest. If, for example, they find the product almost perfect, they can give it a four-star rating, meaning that they colour in four of the five hollow stars. Amazon then adds all the reviews together and displays the average (not the perfect mathematical average, but a number calculated with machine learning) as a number, as well as a five-star scale coloured in according to the average rating.

Should shoppers wish to read verbal feedback as well, they can click on the link right beside the stars to see what previous customers have written about their experience with the product.

 

Moreover, if a buyer wants a glance at all the ratings in detail, they can let their mouse hover over the stars, and a window will pop up with the percentage of the different star ratings.

While this system is not perfect (which one is?), it’s quite straightforward to understand. For example, a 4.3 rating like the one in the above screenshot indicates that people are generally very satisfied with their purchase, and it would be quite safe to buy the product.

 

In August 2025, Amazon changed the seller feedback system significantly by allowing sellers to rate a product only through stars and no longer requiring a comment.

 

Since Amazon is keen on improving its users’ shopping experience, the e-Commerce giant often tests new features, like a somewhat changed rating system.

 

 

Rating system option 1: only one visible star

Instead of the usual five stars in various stages of hollowness, Amazon tried the option of displaying only one star. In addition, the number that usually indicates the average of all ratings should only show the percentage of five-star ratings among all the other ones.

 

According to reports at the time, Amazon tested the rating system in Germany and India in 2023. However, when we accessed Amazon from these countries and several others, we only encountered product pages with the regular rating system. This may indicate that Amazon paused the testing, or maybe even abandoned the new system altogether.

 

At this point, there was no timeline nor any official information about the eventual rollout of the system. When questioned about the new ratings, Amazon spokesperson Maria Boschetti replied, "We are always innovating on behalf of customers to provide the best possible shopping experience."

 

 

Potential issues with this rating system

While the new display definitely looks simpler (fewer numbers and stars clutter the page), understanding the meaning behind it is another story. Since it gives shoppers less information at a glance about the total number of buyers, it’s much harder to draw their own conclusion.

 

For example, a new product with only a couple of buyers may get a few enthusiastic early reviews and thus quite a good rating. On the other hand, an older product with a lot more buyers who had more time and experience with the product may get more accurate feedback, albeit with a lower rating.

 

However, since nobody can see the number of reviews and the other-than-five-star reviews aren’t quantified, it’s much harder to get a clear picture of what other buyers think of the product. It's still possible to click on the number to get more detailed information, but that takes time and effort and may frustrate confused shoppers.

 

And let’s not forget about the opportunities this system gives to fraudsters.

 

 

Advantage: fraudsters

Fraudulent sellers willing to buy fake reviews may stand to gain a significant advantage.

 

Since the system groups together all reviews that didn’t give five stars, sellers and products possessing a large number of five-star reviews have a chance to stand out more than others. And as fake reviews give almost exclusively five stars, fraudsters can gain a lot with this system.

Rating system option 2: no visible ratings in search results

While there was no official word about the fate of the one-star rating system, Amazon launched a test for another ratings-related issue. Namely, the e-Commerce giant considered whether to remove visible ratings from search result pages.

 

So far, tests have been carried out on a limited set of products to determine whether removing product ratings would help make the search result pages easier to understand for consumers. This way, product ratings would only become visible once a shopper clicks through to a product listing.

  

  

 

 

There are valid arguments for both sides. Since dishonest sellers often use fake reviews to dupe consumers, removing these from the equation would prevent unsuspecting shoppers from buying fraudulent products.

 

On the other hand, forcing consumers to actually click through to a product page to see reviews would create new difficulties for both honest brands and shoppers alike. Removing the easiest way to see ratings would make it harder for shoppers to base their purchasing decisions on trusted customer feedback and may result in decreased revenue for brands.
