A rich snippet is a format of the search engine result page (SERP) that includes additional information beyond just the title and URL of the result. Rich snippets can include information such as the product name, price, ratings, and reviews, or the event date and location, among others. The goal of rich snippets is to provide users with more context and information about the results, so they can make a more informed decision about which result to click on.
Rich snippets are generated by adding structured data to the website’s HTML code. The structured data provides the search engines with information about the content of the website, which the search engines can then use to create a more detailed and informative display of the result.
In terms of SEO, having a rich snippet for your website’s results can help increase its visibility and click-through rate (CTR) in the SERP. It also improves the user experience, as users are able to see more information about the website without having to click through to it.
