2/3 page(s) have 1 or fewer incoming internal links (orphan-class)

Some pages have one or no internal links pointing to them ("orphan" pages), so they are hard for search engines to discover and rank. Pages with no internal links get crawled rarely, rank slowly, and build up no authority. Even strong content stays invisible if nothing links to it. Link each orphan page from two or three relevant pages — your main navigation, footer, or related posts. For a service business, link every service page from the homepage nav and from posts that mention it.
