Add a canonical link to the homepage on Shopify
Why it matters
A canonical link names the one address you want search engines to treat as the real homepage, so versions with tracking parameters or without www do not compete with each other. Without it, search engines choose for you.
The fix
- Shopify themes normally print a canonical link in the layout file from Shopify's canonical_url Liquid object. If yours does not, open Online Store, Themes, Edit code, theme.liquid, and add a link rel="canonical" tag in the head using that object, or ask the theme developer to restore it.
