An orphan page is a page that exists on your site but has no internal links pointing to it from any other page. Search engines discover most pages by following links, so an orphaned page is hard to crawl, rarely passes or receives link equity, and often fails to rank — even if it sits in your sitemap.

Honest scope: a single fetch cannot crawl your entire site. This tool fetches your homepage, extracts every internal link on it, then fetches your sitemap (/sitemap.xml) and reports which sitemap URLs are NOT linked from the homepage. That is a strong first-pass signal — pages with no homepage path are the most at-risk — but it is not full orphan detection. A page could still be reached via a deep category page this tool never visited.

Run a full site crawl that visits every page and records every internal link, then compare that complete link graph against your sitemap and analytics/log data. Pages that appear in the sitemap (or get traffic) but have zero inbound internal links across the whole crawl are true orphans. Use this homepage-vs-sitemap tool for a fast triage, and a full site audit for the definitive list.

The homepage is usually the single most authoritative and most-crawled page on a site, and it typically links to your hubs, top categories, and featured content. If an important page is not reachable in one hop from the homepage, that is already a meaningful internal-linking gap worth investigating, regardless of how it is reached elsewhere.

It requests /sitemap.xml at the root of the domain you entered. If that file is a sitemap index (a list of other sitemaps), it reads the child sitemaps too, up to a reasonable limit. If you use a non-standard sitemap location, point the tool at the homepage of the same domain — the sitemap lookup is always done relative to that domain root.

The most common reasons: the link to it lives on a deeper page (not the homepage), the homepage link is injected by JavaScript and not present in the server HTML, or the sitemap URL and the on-page link differ by trailing slash, protocol, or www. The tool normalizes obvious differences, but mismatched canonical forms in your sitemap can still cause false positives.

There is no fixed threshold, but if a large share of your sitemap URLs have no homepage path, your internal linking is probably too shallow. Prioritize fixing orphans that should rank — money pages, key articles, important categories — by linking to them from relevant hub pages, navigation, or related-content modules.
