Orphan pages typically happen by accident — a page gets built and published but never linked from navigation, a related article, or any other page, often because it was created for a campaign or test and the internal linking step got skipped. Because internal links are one of the main ways both users and search engine crawlers discover content, an orphan page tends to get crawled less frequently, receives no internal link equity, and is functionally invisible to most site visitors even if it's technically live and indexed. Finding orphan pages requires comparing a full site crawl (every URL) against the internal link graph (every URL that's actually linked to from somewhere) — any page present in the first list but absent from the second is orphaned and needs internal links added, or should be reconsidered for removal if there's no clear reason to keep it undiscoverable.
Example
A site audit finds 25 landing pages built for past ad campaigns that were never linked from anywhere internally — some get proper internal links added where still relevant, others get retired since the campaigns ended years ago.
