Internal linking refers to the practice of connecting different pages or sections within a website through hyperlinks. These links allow users to navigate between related content on the same website, making it easier to find and access information. Internal linking not only improves the user experience, but it also helps search engines understand the structure and hierarchy of a website. By strategically linking relevant pages together, internal linking can also improve the overall SEO (search engine optimization) of a website. In short, internal linking is a crucial aspect of website design and organization, helping both users and search engines to efficiently navigate and understand the content within a website.
