An orphan page is a web page without any internal links pointing to it. It's not linked to in the main navigation, or from any links on pages.
Users navigation your website have no way of reaching that orphan page. Since internal links are an important indicator of relevance of that page to search engines, an orphan page will not be likely to rank.
The fix for an orphan page can be simple: put some internal links to the orphan page from other pages, or, if the page is no longer relevant, remove it.Back
