To help publishers feature their content from third-party sites in local Knowledge Panels, be it editorial critic reviews, or aggregates user ratings, Google introduces "Reviews from the web."
The feature is rolled out globally on mobile and desktop.
The feature accompany already available "best-of lists" and "critic reviews" features. On the desktop, Reviews from the web appears in the Knowledge Panel as critic reviews. While in mobile, they appear above critic reviews and best-of-lists in a horizontal presentation.
The feature brings aggregated user ratings of up to three review source sites to Knowledge Panels for local places. Reviews from the web will appear across many verticals including shops, restaurants, parks and more, explains Google.
By implementing review Schema markup, any publisher is eligible for inclusion of their site's user-generated contents to the knowledge panel and prominent placement in mobile results.
The order will be determined by "relevance," Google said "Critic reviews possess an editorial tone of voice and have an opinionated position on the local business, coming from an editor or on-the-ground expert."
However, as of now, only qualifying publishers in the U.S. can participate in the critic review feature in local Knowledge Panels.
"Add the Local Business markup to help Google match reviews to the right review subject and help grow your site's coverage," writes Google.
