Product information before and after variant selection
Watch if Variant or Quick View plugins change the title. The final title must continue to match the actually opened product page.
Compare initial product HTML with the variant status selected according to JavaScript. General description and reachable product links should not accidentally arise only after an interaction.
Where to check the setting in WooCommerce
Open the product URL directly and check the name, description and basic price before selecting a variant. For variable products, then document the selected variant. A price by choice and a price range in the first answer do not have to have the same value.
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 WooCommerce
Test direct call, variant change and return via the browser. Product name, metadata and visible state must describe the same product view.
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.
Regarding: WooCommerce on WordPress. Block and classic product templates as well as SEO extensions can have different output locations.
