Product assignments, category paths and cross-selling
Check product descriptions and category menus after a change of range. Deleted articles are often preserved in editorial references.
Check menu links and automatically generated references from related products and categories. A deactivated article can still be in a manually maintained recommendation.
Where to check the setting in WooCommerce
Check product categories, linked products, and cross-selling entries and saved links in the description. Compare the destination path with the WooCommerce permalink settings. A new product base does not correct hard-coded old description links.
Example of this specific finding
Illustrative control case: A guide links to /sortiment/alt/, the landing page responds with 404. The location is the guide, the error answer comes from the destination.
follow-up audit in WooCommerce
Retrieve the link at its location after the product update. Remove a deleted recommendation or replace it with a really suitable product.
Change the link at the location to a suitable, accessible address. After that, retrieve the same found page and follow the link that was actually issued.
Derogations and scope
If there is no suitable replacement, removing or rephrasing can be better than redirecting to the start page.
Regarding: WooCommerce on WordPress. Block and classic product templates as well as SEO extensions can have different output locations.
