A page nothing links to is discovered only through the sitemap, crawled rarely, and treated as unimportant — because in the site's own structure it demonstrably is.
The finding reads:
critical orphan no internal link points at this page
Link to this page from the section's hub pages. Make the anchor descriptive, not “read more”.
Collapsed when it fires template-wide. If it appears on 90% or more of the pages — or of one language version — of a site with at least 20 pages, it is a property of the template and is reported once, with the count, instead of once per page.
Suppressed on JavaScript shells. A page with no text in its source HTML would trip this check for a reason that is already reported as js-shell, and repeating it four times is not four times as informative.
