What Is an Orphan Page? | SEO Glossary

An orphan page is a page on your website that receives no internal links from any other page. Since search engine crawlers discover pages by following links, orphan pages are effectively invisible to them.

Why It Matters

Search bots navigate sites by following links. An orphan page is completely cut off from this discovery path, meaning crawlers may never find it—even if the content is excellent. While XML sitemaps can help, the absence of internal links signals to search engines that the page isn't important to the site. The result: poor or no rankings, and wasted effort on content that nobody sees.

Common Causes

Site redesigns: Internal links to existing pages get dropped during CMS migrations or redesigns.
Content accumulation: As blog posts pile up, older articles lose their connections.
Category/tag changes: Restructuring navigation can leave pages outside any browse path.
Deleted hub pages: The only page linking to the orphan gets removed.
URL changes: Changing URLs without redirects breaks existing internal links.

How to Find Orphan Pages

Crawling tools: Screaming Frog, Ahrefs Site Audit, or Semrush automatically flag pages with zero internal links.
Google Search Console: Check the "Pages" report for URLs marked "Discovered — currently not indexed" that lack internal links.
Sitemap vs. crawl comparison: URLs in the XML sitemap but not found by the crawler are likely orphans.

How to Fix Them

Add internal links: Link to the orphan page from relevant existing content—the simplest and most effective fix.
Connect to hub pages: Add links from category pages, pillar pages, or resource pages.
Include in sitemap: Ensure the page is in the XML sitemap as a crawling safety net.
Remove or redirect: If the orphan page no longer adds value, 301-redirect it to a related page or delete it.
