Sales channel, product variants and storefront head
Control the head blocks of the active storefront adjustment. An overwritten Twig template can displace the standard output for a page type.
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: An article page and its tracking variant provide the same text, but not a preferred URL. The variants must first be compared in terms of content.
<!-- Auf Artikel und identischer Trackingvariante -->
<link rel="canonical" href="https://example.org/ratgeber/bremsen/">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 these identical variants, consistently specify the clean article URL. Internal links and sitemap should give the same address.
Derogations and scope
A unique page without a canonical is not automatically unindexable. Even an existing canonical does not guarantee the selection by Google.

Definition, system-independent causes and further correction examples: A missing canonical is not a blanket indexing error
