Featured Snippets are short snippets of text that appear at the top of Google’s search results in order to quickly answer a searcher’s query. The content that appears inside of a Featured Snippet is automatically pulled from web pages in Google’s index. Common types of Featured Snippets include definitions, tables, steps and lists.
Featured snippets aim at answering the user’s question right away (hence their other well-known name, “answer boxes”). Being featured means getting additional brand exposure in search results.
