Products and taxonomies in the active sitemap provider
After Permalink changes, check the product sitemap and its cache. A redirect can save visitors, but it does not replace an updated sitemap.
The product list in the sitemap usually comes from the WordPress/SEO integration. Check publication, visibility, and selection of product categories separately. A product not visible in the catalogue is not automatically technically unreachable.
Where to check the setting in WooCommerce
In the active WordPress or plugin sitemap provider, check whether products and product categories should be included. Compare the publish status of the product with its listing; catalog visibility and SEO indexing rule can perform different tasks.
Example of this specific finding
Illustrative control case: The sitemap calls /performance-alt/, which redirects to /performance/ permanently. The generator uses an outdated URL source.
follow-up audit in WooCommerce
Compare an active, a removed and a deliberately excluded product after a regular sitemap rebuild. Also retrieve the actually generated product part sitemap.
Take the final desired address directly into the sitemap and test the regular rebuild. Appropriately pass forwarding for old calls.
Derogations and scope
Do not remove the working redirect, just so that the old sitemap URL returns 200.
Regarding: WooCommerce on WordPress. Block and classic product templates as well as SEO extensions can have different output locations.
