A featured snippet appears as a framed, highlighted box that Google displays above the regular search results. It contains text, lists, or tables extracted from a website that provide users with a quick answer to their question.
Because of its often very prominent position, the featured snippet is also referred to as “Position Zero.” It usually appears for clearly phrased questions, such as those seeking definitions, step-by-step instructions, or comparisons. The content that makes it into a featured snippet is characterized by a clear structure and precise answers.
