Google Search's product reviews system and your website

The product reviews system aims to better reward high quality product reviews, which is content that provides insightful analysis and original research and is written by experts or enthusiasts who know the topic well. This page explains more about how the product reviews system works, and what you can do to assess and improve your content.

How the product reviews system works

The product reviews system works to ensure that people see product reviews that share in-depth research, rather than thin content that simply summarizes a bunch of products.

The product reviews system primarily evaluates product review content on a page-level basis. However, for sites that have a substantial amount of product review content, any content within a site might be evaluated by the update. If you don't have a lot of product reviews (a really substantial not-single-digit-percentage part of your entire site is made up of them), a site-wide evaluation is not likely to happen.

Currently, this system applies to the following languages globally: English, Spanish, German, French, Italian, Vietnamese, Indonesian, Russian, Dutch, Portuguese, Polish.

Structured data might help us better identify if something is a product review, but we don't solely depend on it.

What does this system and updates to it mean for my site?

To learn more about how to create content that's successful with the product reviews system, see our help page on how to write high quality product reviews.

Periodically, we improve how the product reviews system works. When we do this in a notable way, we share this as a "product reviews update" on our Google Search ranking updates page.

Assuming improvements have been made, content that was impacted by a product reviews update might not recover until the next product reviews update is released. However, note that our automated assessment of product review content is only one of many factors used in ranking content, so changes can happen at any time for various reasons.
