A page with no internal links pointing to it, so crawlers and authority struggle to reach it.
An orphan page is cut off from the rest of your site's link graph. Even if it's indexable, nothing internal points to it — so crawlers may not find it, and the authority that flows through internal links never reaches it. It sits in the index doing nothing.
The fix is usually simple: link to it from relevant existing pages. CommandSEO surfaces orphan pages on the canvas so they're easy to spot and connect.
