An orphan page exists on your site but nothing else on your site links to it. Crawlers may still find it through a sitemap or an external link, but without internal links it gets little signal about its importance and is often crawled rarely. Visitors browsing the site cannot reach it at all. Orphans usually appear through redesigns, campaigns, CMS quirks and programmatic page sets.
How orphans happen
Orphans are rarely deliberate.
- Landing pages built for a paid campaign and never linked from the site
- Navigation changes that drop links to older pages
- Blog posts that slip off paginated archives with no other links
- Programmatic pages only listed in a sitemap
- Pages linked only from JavaScript elements crawlers do not follow
- Old pages left live after a migration
Finding them
Orphans are pages that exist in one list but not in your crawl. Crawl the site from the homepage, then compare the URLs found with other sources: your XML sitemaps, your CMS export, analytics landing pages, Search Console's performance data and server logs. URLs that appear in those sources but not in the link crawl are orphans. Many desktop crawlers can do this comparison automatically when connected to sitemaps and analytics.
What to do with each orphan
Decide page by page. If the page is useful and should rank, link to it from relevant hubs, related pages and navigation. If it duplicates another page, merge it and redirect. If it is obsolete, remove it and return 404 or 410, or redirect if it has backlinks. Campaign landing pages that should stay out of search can be noindexed and left unlinked deliberately.
Example
Comparison pages lost after a redesign
A fictional design tool, Framewell, had a footer with links to its ten "vs" comparison pages. A redesign shortened the footer and the links disappeared. The pages are still in the sitemap, but Search Console shows impressions falling over the following months.
Adding a Compare hub page linked from the footer and the pricing page, with each comparison linking to the others, reconnects them.
Common mistakes
Relying on the sitemap alone
A sitemap entry helps discovery but does not replace internal links, which signal importance and give visitors a path.
Linking orphans from one buried page
A single link from a low-level page barely helps. Link from relevant, well-linked pages.
Questions
They can if Google finds and indexes them, especially with external links, but they usually perform worse than equivalent pages that are well linked internally.
A few are harmless. Large numbers of orphaned, low-value pages can add to index bloat and waste crawling, so prune or connect them.
