Google Merchant Center has introduced new attributes for CSS product pages, allowing CSS partners to submit product ratings and review counts. These updates include the Rating [rating], Minimum rating [minRating], Maximum rating [maxRating], and Review count [reviewCount] attributes. All ratings submitted are normalized to a 1-5 scale by Google, enhancing the potential for customized ranking signals in free listings.
The Rating [rating] attribute is optional and indicates the average product rating on CSS product pages. It requires minRating, maxRating, and reviewCount attributes, with the rating value needing to fall between the min and max.

The Review count [reviewCount] attribute shows the number of reviews a product has received and is mandatory when using the rating attribute. It must be a positive integer, providing additional ranking signals for free listings.
These changes aim to provide more comprehensive and customizable product data for Google surfaces, impacting how products are displayed and ranked in free listings.
