How to find orphan pages on your site

Before you start

• A crawler, or a build script
• Your XML sitemap

The steps

1. 1

   Step 1: Crawl from the home page

   Follow internal links only. Record every URL reached.

2. 2

   Step 2: Export your sitemap URLs

   Every loc entry from sitemap-0.xml, or from each child of the index.

3. 3

   Step 3: Compare the two lists

   Sitemap URLs not present in the crawl are orphans.

4. 4

   Step 4: Check Search Console

   Orphans commonly appear as "Discovered — currently not indexed", which confirms the diagnosis.

5. 5

   Step 5: Decide page by page

   Either link the page from somewhere genuinely relevant, or remove it if nothing needs it.

6. 6

   Step 6: Automate the check

   Put it in your build so the problem cannot silently return — a page nothing links to should fail the build, not be discovered a year later.

Why an orphan usually stays unindexed

A sitemap entry is a suggestion; an internal link is a signal of importance. A page with no inbound links reads as unimportant regardless of what the sitemap says, and search engines act accordingly.

The worst of both outcomes

Leaving an orphan in the sitemap means it is crawled, judged, and counted toward the site’s overall quality assessment without ever being useful. Either link it or remove it — leaving it is the only genuinely wrong option.

Orphans that should simply be deleted

An old landing page from a campaign that ended, a duplicate created during a migration, a tag archive with one entry. If nothing links to it and nothing needs it, removing it is better than manufacturing a link. Return a 410 rather than a 404 where you are certain it is permanent, and remove it from the sitemap in the same change so the two never disagree.
