'For context' secondary tab appearing on results page
As reported by multiple outlets, Google has started testing a secondary 'For context' box in the 'Top stories' section of its main search results page.
Typically, this carousel shows featured news articles around a searched topic, but with the inclusion of the new box, it also offers a second, broader story on the same topic, giving you a better, clearer understanding of the news.
The story mentioned under 'For context' also comes from the same outlet that had published the main featured story, seemingly indicating that Google will not use this to redirect traffic from one publication to another - which might be a concern for many.
The change is small but may come extremely handy in gaining a detailed insight into something that is trending.
