An internal link is a hyperlink that connects one page of a website to another page within the same website. These links are used to navigate and direct users to related or relevant content within the website, making it easier to explore and access information. Unlike external links, which lead to pages on other websites, internal links keep users within the same website. They not only help with website organization and structure, but also improve user experience by providing a seamless and interconnected browsing experience. Internal links are an essential aspect of website design and play a crucial role in improving website traffic and search engine optimization.
