External links are hyperlinks that direct users from one website to another. They are often used to provide additional information, reference sources, or connect to related content. For example, a blog post about healthy eating might include external links to nutrition studies or recipes on other websites. These links can enhance the user experience by offering more resources and insights. However, they can also lead users away from the original site, which is why website owners should use them judiciously. Properly managing external links can improve a site's credibility and search engine ranking.
