Links that navigate from one page to another page on the same domain. Internal links can be inserted on a page, in the main navigation menu, or in the sitemap.
Internal links can be used to indicate the importance of a page on a site. For example, a page that is directly linked from the home page compared to a page that is four clicks from the homepage.
Internal links are important because Googlebot crawlers follow internal links to navigate your site and find new pages.
