When asked in a “Google SEO office-hours” video whether internal linking was still important for SEO, John Mueller said:
Internal linking is an essential aspect of SEO as it helps search engines understand the structure and hierarchy of a website. Internal links connect different pages within a website, allowing search engines to discover and index content more efficiently. They also play a crucial role in distributing authority and relevance across a website. By linking relevant pages together, internal links help search engines determine the importance and topical relevance of different pages on a website. Therefore, it is important to strategically incorporate internal links throughout a website to enhance its SEO performance.
Internal links do this by directing the flow of PageRank around your site. Even though the PageRank toolbar disappeared in 2016, PageRank is still a signal that Google uses.
PageRank, developed by Google’s co-founders Larry Page and Sergey Brin, is a crucial algorithm that determines the authority and importance of web pages. PageRank operates on the principle of citation analysis, considering the number and quality of links pointing to a page as an indicator of its relevance and authority. While the PageRank toolbar is no longer visible to the public, Google still uses PageRank as one of the many signals to determine the ranking of web pages in search results. Internal links play a significant role in distributing PageRank throughout a website, helping Google understand the importance and relevance of different pages.
