Google is displaying a new menu icon next to most search results that can be tapped to quickly view additional context about the site behind the result. The summary information from the "About this result" feature is sourced from Wikipedia, if there is a page on Wikipedia about the site.
The idea is to provide users with a way to find more information without having to an additional search about the sites in the search results.
Kearns argues the additional information can provide context and "peace of mind" to the user if they're researching a sensitive subject, like health or financial information.
A key example Google provides for the feature is the Lancet, which Wikipedia describes as one of the world's best-known peer-reviewed general medical journals. This could be useful for people researching a subject with a lot of noise, like COVID-19.
Once the menu icon is pressed on a smartphone, an "About this result" card pops up with a brief description of the site, the source of that information, and whether the connection to the site is secure and uses HTTPS. If a Wikipedia page is not available, Google shows additional context, such as when it first indexed the site.
