EXT:seo, Side Properties and Detail Extension
Examine the Robots setting of the target dataset and possible TypoScript specifications. A canonical on a deliberately excluded area does not resolve the conflict.
Open the dataset of the affected page and compare a set canonical override with the site base and the real language URL. In the case of a news or product detail page, you also check whether the extension brings in its own canonical source. A fixed target fluid snippet shall not double the dynamic assignment.
Where to check the setting in TYPO3
In TYPO3 13.4, control the SEO page properties and output of EXT:seo. For detailed pages, you also check the CanonicalGenerator or adjustments to the extension. Do the site’s basic URL and language configuration match the published target?
Example of this specific finding
Illustrative control case: A publicly advertised product variant refers to a main product with noindex. If the main product is to appear in the search, its exclusion contradicts this intention.
follow-up audit in TYPO3
Get a default page and a detailed view of the same site. If the finding occurs only in the detailed view, first examine its output instead of the global site configuration.
For the main product and variant separately decide which URL should be indexed. Only then canonical and indexing requirements be corrected together.
Derogations and scope
Noindex on the target does not blindly remove: the main product may have been deliberately withdrawn. Another appropriate content or removal of the variant may be required.
Reference: TYPO3 13.4 with EXT:seo. For other major versions and own extensions, responsibilities may differ; check the actually installed output.
