Orphan Page
In one line
An orphan page is a URL that no other page on the site links to — invisible to internal navigation and badly disadvantaged in discovery, evaluation and ranking.
Going deeper
An orphan page is a URL that lives in your sitemap but has no internal links pointing to it. Bots can still find it through the sitemap, but with no incoming internal links it gets no PageRank flow and the evaluation suffers accordingly.
The causes are mundane and recurring: a campaign landing dropped from the nav after launch, a migration that broke the old category links, A/B variants that quietly stuck around. Screaming Frog or Ahrefs will surface them quickly — pull the list where 'in sitemap = yes' and 'internal links = 0'.
The fix is simple too. If the page deserves to live, link to it from relevant categories and posts so it rejoins the graph; if it does not, 301 or 410 it. The same logic applies to AI search — for an LLM to consider citing a page, it generally needs to be reachable in a normal site graph, not stranded.
