Orphaned pages are pages that lack internal links and are isolated from the rest of your website. They can harm your SEO performance and user experience by reducing your site's crawlability, authority, relevance, and engagement. To address orphan pages, you need to identify them using various tools and methods, and link them with relevant pages on your site. This will improve your site's navigation, visibility, and success. Orphan pages in seo are opportunities waiting to be seized, not problems to be ignored.
