Any link that takes users from one page of your website to another is called an internal link.
Links are used to navigating your website’s content by both visitors and search engines.
Links help your users explore your website and discover the material they’re looking for.
Your article needs links to rank. When your posts and pages are linked to another website, Google finds them more easily. Additionally, internal links connect your articles and help Google understand the layout of your website.
They can help you create a hierarchy on your website so that the most significant pages and posts receive more link value than other, less significant ones.
As a result, using the proper internal connection approach might increase your SEO.
