Liquid object canonical_url and additional theme output
Check fixed canonical overrides against the current product address. An outdated handle should not be an additional forwarding station in the canonical.
In the theme head, look for canonical_url and more canonical tags from snippets or apps. Compare the direct product path to a product address in the collection context.
Where to Check Settings in Shopify
In the head of layout/theme.liquid, check the output of the liquid object canonical_url and additional SEO snippets. Compare direct product and collection product paths. Do not replace the platform output with a fixed shop homepage.
