Sitelinks refer to the additional links that appear below the main website link in a search engine result page. These links provide users with direct access to specific pages within a website, making it easier for them to navigate and find the information they are looking for. Sitelinks are typically chosen by search engines based on the relevance and popularity of the pages, and they can greatly enhance the user experience by saving time and effort in searching for specific content. They also serve as a powerful tool for website owners to showcase their most important and valuable pages, increasing their visibility and potential for traffic. In short, sitelinks are a valuable feature that improves the accessibility and usability of a website for both users and website owners.
