An internal link is a hyperlink that points to a different page located on the same website. This is in direct contrast to an external link, which directs users to a page hosted on a separate web domain.
Internal links are vital because they help search engines understand the structural hierarchy of a website and the relationships between its various pages. Additionally, they significantly assist users in navigating the site more conveniently.
Furthermore, internal linking is considered one of the most important on-page ranking factors. Consequently, internal linking tactics frequently play a core role in the overall SEO strategy. Carefully choosing the anchor text (the clickable text within a link) for internal links can encourage visitors to spend more time on your site. Creating a strong network of internal links to your content can also contribute to boosting your domain authority. All of these factors help to improve your page’s position in search results.
