Google is updating and working on the look of its product-oriented knowledge panels on mobile to show even more details about the particular item or product in the search results.
In an example by Vlad Rappoport (the image below), the shopping knowledge panel has a blue header providing details about the product and a new carousel featuring third-party editorial reviews and separate tabs for stores in addition to reviews with a number of different options and features, like videos, to provide a one-stop resource for product info.
