Google’s “featured snippet” is the text box that sometimes shows up at the top of results page with an answer to a question. For example, if you look up “how much does gas cost in Texas”, the featured snippet shows an excerpt from a chosen search result with the specific answer, “$2.51”, highlighted in bold. These snippets are also commonly used in voice search.
Often times, the link that gets displayed in the featured snippet is not the first result. Sometimes, it is toward the bottom of the page. To rank for featured snippets, Google tends to favor content that is brief and to the point, especially short answers and bulleted lists.
In addition to the featured snippets, the same criteria can help you rank for Google’s “People also ask” widget. When links to your site show up in these widgets, it gives the appearance that your site is trustworthy, and more people will click on it.
