Google product reviews update
The Google product reviews update aims to promote review content that is above and beyond much of the templated information you see on the web. Google said it will promote these types of product reviews in its search results rankings.
Google is not directly punishing lower quality product reviews that have “thin content that simply summarizes a bunch of products.” However, if you provide such content and find your rankings demoted because other content is promoted above yours, it will definitely feel like a penalty. Technically, according to Google, this is not a penalty against your content, Google is just rewarding sites with more insightful review content with rankings above yours.
Technically, this update should only impact product review content and not other types of content.
