Does Navigation Affect SEO?
Google has four ways to discover your content. i) Crawling with their bots, ii) the Sitemap file, iii) direct submissions you do through URL Inspection in Search Console, and iv) users visiting pages through the Chrome browser. There are more ways we suspect they use, but that is not the scope of the paragraph. When a bot crawls the site, navigation and links are the ones to indicate there is more content to discover. They show the path guiding the Googlebot from page to page. Pages not linked in any way may never be found, this I call buried content. It is a white-hat way to hide your content from the search engines ;)
