Sales channel, product variants and storefront head
Check the effective Robots details of the landing page in the relevant sales channel. A canonical to an excluded category does not resolve the conflict.
Compare the active domain of the sales channel with product and variant addresses. Then check if the theme or extension changes the canonical output. A proper SEO URL in the backend does not yet prove the right head of the storefront.
Where to check the setting in Shopware
In the product, check the SEO setting for a common canonical URL of the variants. Then compare the selected variant, the sales channel domain and the canonical in the Storefront head. In the case of own Twig edition, no second contradictory day may arise.
Example of this specific finding
Illustrative control case: A publicly advertised product variant refers to a main product with noindex. If the main product is to appear in the search, its exclusion contradicts this intention.
follow-up audit in Shopware
Retrieve the same product in the affected sales channels and with a specific variant. Document channel assignment and desired main product.
For the main product and variant separately decide which URL should be indexed. Only then canonical and indexing requirements be corrected together.
Derogations and scope
Noindex on the target does not blindly remove: the main product may have been deliberately withdrawn. Another appropriate content or removal of the variant may be required.
