Definition
An orphan page is a webpage on a site that lacks internal links pointing to it, making it inaccessible through the site’s normal navigation. This means users and search engines cannot find these pages by browsing or crawling the website, though they can still be accessed via external links or direct URL entry.
User Cases
Orphan pages often occur due to poor internal linking practices, site migrations, or when links are deleted. For instance, a new product page not linked from the main catalog becomes an orphan page. Similarly, if a blog post that linked to another is deleted, the latter may become orphaned if no other internal links point to it.
Why It Matters for SEO
Orphan pages can negatively impact SEO as search engines rely on internal links to discover and index content. Without these links, orphan pages are less likely to be found and indexed, leading to poor rankings and reduced organic traffic. Even if indexed, they may rank poorly due to a lack of authority and relevance signals from internal links.
Related Concepts
Related concepts include internal linking, site navigation, and dead-end pages. While dead-end pages have no outbound links, they may still have inbound links, differing from orphan pages which lack inbound internal links. Understanding these concepts helps in optimizing site structure for better SEO performance.
