Internal backlinks are the links referring from one page to another page on the same domain. Internal links help visitors navigate your website by providing a way to move between different pages. External links are links that come from other websites to your website. These are essential because they help show search engines that your site is a good source of information for searchers. When a link is clicked, the search engine assigns some of its ranking power to the page that's being linked, this helps to boost the page's authority and improve its ranking in the search results.
