Limit the findings in TYPO3
A page hidden in the menu can still be indexable and in the sitemap. Check whether suitable context links provide the desired access.
Where to check the setting in TYPO3
In the Page Tree, check Menu Hide and Page Access separately. A published page can be in the sitemap and missing from the menu. Based on the task of the page, decide whether an editorial link, a menu position or a link from a suitable record list is needed.
Example of this specific finding
Illustrative control case: A URL is in the sitemap, but was not reached from the starting point via any recorded internal link. This can be an orphaned side or a border of the crawl.
follow-up audit in TYPO3
Check starting points, crawl limit, exclusions, and JavaScript navigation. Is the important page really not linked, add a suitable context link and repeat the crawl.
Derogations and scope
The absence in a limited crawl does not prove that there is no link on the entire website.
Reference: TYPO3 13.4 with EXT:seo. For other major versions and own extensions, responsibilities may differ; check the actually installed output.
