Product/Category Attributes in the Right Store View
Control metadata and inheritance per Store View. A global fixed title can overlay local or product-specific values.
A meta title can be maintained globally and overwritten in a store view. Also, check if the theme or an extension sets additional prefixes and suffixes.
Where to check the setting in Magento
For the product or category, open the Search Engine Optimization fields in the affected Store View. Control inherited values and use default value. For the general title fallback, check the HTML Head area under Content → Design → Configuration.
Example of this specific finding
Illustrative control case: The URLs /consultation/ and /training/ are both titled “Performances”. A common template fallback displaces the individual page titles.
follow-up audit in Magento
Retrieve two products and a category with consciously different language values. Only after cache updating will the actual public expenditure be assessed.
The delivered titles distinguish the actual tasks, such as “SEO consulting for companies” and “SEO training for your team”. Test the fallback even in an empty editorial field.
Derogations and scope
A recurring brand name is usefully possible. Not every common title component makes two titles duplicates.
Reference: Magento Open Source or Adobe Commerce with classic storefront. Consider store views and extensions; other storefront architectures have their own configurations.
