Google is always trying to improve the way users find information and data that is as accurate as possible. The search engine recently updated its algorithms with first-hand research. It also shared the latest progress to garner high-quality product reviews in line with user search history.
The company is working to prioritize product reviews that are helpful and in-depth regarding product details.
In an official blog post, software engineer at Google, Perry Liu wrote:
Our first updates were designed to, among other things, help ensure reviews come from people who demonstrate expert knowledge and first-hand research about products.
Google says that it will feature reviews from people who have used the product on the top, especially when they feature unique information. Comparison of different products, explanation of an item, etc. will also be given a higher ranking.
