Builder widgets and reloaded content
Check whether a frontend plugin subsequently overwrites the title already issued by the SEO plugin. Decisive is the deviation between the initial HTML and the finished view.
Compare the public server response to the state after loading all builder scripts. A visible text in the editor or in the preview is not proof that the direct public retrieval already contains it.
Where to check the setting in WordPress
Go to the URL directly logged out and compare page source text and browser DOM. If the missing content is in a builder widget, check its data source and loading condition; a widget that loads content only after a click does not deliver it in the first HTML.
Example of this specific finding
Illustrative control case: After clicking on a product, the document title of the category remains. When directly loading the product, on the other hand, the right title appears.
follow-up audit in WordPress
Also test as a logged-out visitor. Consent, optimization plugins and delayed JavaScript can change the result compared to a logged-in preview.
Pair title management to the actual route change and test for direct call and app navigation. When navigating back, the matching title must also be restored.
Derogations and scope
A dynamically set title can be processed; the result here concerns the wrong or unstable value, not JavaScript itself.
Related: WordPress with classic or block theme. SEO plugins and page builders are different; there is no universal menu path for all installations.
