Canonical tags tell search engines which version of a page to prioritize. Without them, duplicate or similar pages may split ranking signals.
What to do: Add a canonical tag to the page to indicate the preferred URL that search engines should index. This helps prevent duplicate content issues and ensures ranking signals are consolidated to the correct version of the page. On Shopify, canonical tags are generated automatically by the theme. You may need to review your theme code to ensure they are present and configured correctly.
You should usually see something like this inside the <head> section:
If it’s missing, add it inside <head>, before </head>.
Note: You should not manually change the canonical URL unless there is a specific issue. Shopify automatically outputs the correct canonical URL for the page.
Since this is a theme-related issue, we recommend contacting your theme developer or theme support team to ensure that the canonical tag is being generated correctly. Alternatively, you can also contact Shopify Support for further assistance.
