Publishers and webmasters might not like this new feature Google is testing.
Google has started testing and potentially rolling out a new feature in search that shows a carousel with a list of answers directly within the search results snippets. It shows the main search result snippet, and below it, it shows a carousel of answers picked from the content on the page the snippet is linking to.
This comes in handy with forum-related threads where someone asks a question and multiple people give their answers. In addition, Google is labeling which answer is the “best” and shows that answer first in the search results.
Here is a picture from @glenngabe:
I suspect Google is picking the best answer from a label in the thread itself.
Of course, this can be a concern for those who run answer sites. Instead of a searcher clicking from Google’s search results to an answer site webpage, the searcher can quickly see a snippet or the full answer in these answer carousels.
