Site links refer to a set of hyperlinks that appear below the main search result on a search engine, providing users with quick and direct access to specific pages within a website. These links are typically displayed in a row or column format and are chosen by the search engine algorithm based on their relevance and popularity. Site links not only improve the user experience by allowing them to easily navigate to relevant pages, but they also increase the visibility and credibility of a website by showcasing its most important and frequently visited pages. In addition, site links can also help drive more traffic to a website and improve its search engine ranking.
