Featured Snippets are a type of rich result that appear at the top of a search engine results page (SERP) when a user enters a question. They are designed to give users a quick and easy answer to their question and save them having to click through to a website to find the information they are looking for.
Featured snippets are usually displayed in a box that stands out from the other organic search results and often contain a title, a summary of the answer and the source of the information. Depending on the search query and search engine, they can contain different formats such as lists, paragraphs, tables, etc.
The information contained in a Featured Snippet usually comes from a website that ranks high in the search results for the search query in question. Websites that want to be considered for inclusion in Featured Snippets should ensure that their content is well-written, informative and relevant to the user's search query. They should also use structured data (e.g. schema.org) so that search engines understand the content and format of their pages.
It is worth noting that a Featured Snippet can be beneficial for websites and brands as it increases visibility and brings more visitors to the website in the SERP.
