External Link

An External Link is a link that points to a domain other than the page on which it is located.

From the perspective of the linking site, these links are useful in providing value to visitors and helping them to further their online experience, especially when they point to high-quality, content-relevant sites. From the perspective of the site receiving them, external links are called backlinks and are important for SEO because they can help build the authority of the site, potentially improving its organic visibility.
