Google has introduced a new type of featured snippet using which searchers can use drop-down tabs to further explore various subtopics. This new type of dedicated to displaying more in-depth information about a topic, similar to how Google displays featured snippets for individual topics, Google can now display a featured snippet that details the differences and/or similarities between two things.
Google provided an example of a comparison between quartz and granite, with expandable subtopics related to cost, benefits, weight, and durability.
Now when you search for something like [quartz vs. granite], you’ll see a panel with a set of relevant subtopics to explore. As another example, when you search [emergency fund], you’ll get a quick view of information that relates to the recommended size, purpose, and importance of an emergency fund, and you can easily click the links to these relevant sources to learn more. This new format is meant to help guide you with what we understand to be common, useful aspects of the topic and help you sift through the information available, all with the goal of delivering the most relevant results for you.
These new panels are automatically generated based on Google’s understanding of these topics from content on the web.
