Page Properties, PageTitle/MetaTag API and Fluid
Control the description field of the page and possible overwrites through the detail extension. A news page can use different data than the surrounding page.
Track the value from the page title or SEO field to the output. Extension detail views can be handled by a separate title provider or a metadata call. A global fluid fragment can overlay or additionally output these values.
Where to check the setting in TYPO3
In TYPO3 13.4, check the SEO title in the page properties and priority under config.pageTitleProviders. The SeoTitlePageTitleProvider can overwrite the page title; a detail extension can use its own provider. Description and Open Graph must be checked separately via metadata or the MetaTag API.
Example of this specific finding
Illustrative control case: The service page explains repair, maintenance and appointment, but does not provide its own meta description.
follow-up audit in TYPO3
Compare a default page, an extension detail page, and a record with an empty optional field. Thus, fixed template values and missing fallbacks become visible.
Formulate a concise description from the actually offered services and check it in the delivered head. The text is intended to supplement the title.
Derogations and scope
Google can also create a snippet without a description and replace an existing description. The field is not a display guarantor.
Reference: TYPO3 13.4 with EXT:seo. For other major versions and own extensions, responsibilities may differ; check the actually installed output.
