Orphan Page
An orphan page is a page with no internal links pointing to it. Crawlers cannot reach it by following links, users cannot navigate to it, and it usually ends up unindexed or ranking far below what its content would otherwise justify.
Why it matters for your rankings
Orphan pages are structural statements. A page nothing links to is one your own site says nobody needs, and search engines read that signal exactly as it appears.
They accumulate through ordinary work rather than negligence. Campaign landing pages built outside the CMS, old product pages removed from navigation when a category was restructured, and content migrated without its links all end up stranded. Sitemaps mask the problem, because Google can discover the URL and still treat it as unimportant. Finding orphans requires comparing a crawl of your actual link graph against your full URL list, which is why they persist for years on sites that have never run that comparison.
How to check it on your site
Crawl and compare
Run Screaming Frog with the XML sitemap and analytics connected, then use the Orphan Pages report to list URLs with no inlinks.
Cross-reference analytics
Pages receiving traffic but showing zero internal links are orphans that still matter commercially.
Decide keep or remove
Link genuinely useful orphans from relevant pages. Redirect or delete the ones that serve no purpose.
Recheck after migrations
Restructures and replatforms are the main source of new orphans, so re-run the report afterwards.
