Pages with no internal links pointing to them — reachable by URL, but invisible to anyone navigating your site.
An orphan page exists and may even be indexed, but nothing on your own site links to it. Search engines discover pages mainly by following links, so an orphan has to be found some other way — a sitemap entry, an external link, an old crawl. Users cannot reach it by browsing at all. Orphans usually appear by accident: a campaign landing page, a post that fell out of a category, or pages left behind by a migration.
Find them by crawling your site and comparing that URL set against sources that do not depend on internal links — your XML sitemap, the Search Console pages report, analytics, and server logs. Anything in those lists your crawl never reached is an orphan. Then triage rather than fix blindly: link it properly if it has value, consolidate and redirect it if a better page exists, remove it if it should not be there. The one thing not to do is bulk-add footer links just to clear the report.
Orphans are a diagnostic, not a defect. A steady trickle means your publishing workflow has no step that asks “what links to this?”; a sudden spike almost always means a migration dropped a navigation pattern or a template stopped rendering a module. Read them as evidence about process and architecture, and fix the cause. Their real cost compounds: orphaned pages receive no internal authority, sit low in crawl priority, and quietly accumulate as dead weight that dilutes the site’s topical signals.
