Page is missing a preferred URL tag

What this means for your business

There's a configuration issue that can confuse Google about which version of a page to rank. This can split your SEO value across duplicate pages, making all versions rank lower.

How to fix it

  1. 1A canonical tag tells Google which URL is the "main" version of a page when multiple URLs show the same content.
  2. 2Check your page source for <link rel="canonical" href="..."> in the <head>. The URL in that tag should match the current page's URL (or the preferred version of it).
  3. 3Common problems: canonical points to a different domain, a 404 page, or the homepage instead of the actual page.
  4. 4Ensure your canonical URLs use HTTPS, not HTTP, and are consistent with your preferred URL format (www vs non-www).
  5. 5If the page has no canonical tag, add one pointing to itself to prevent Google from choosing a canonical arbitrarily.
  6. 6Check for conflicting canonical signals: if your sitemap includes a different URL than your canonical tag, fix the sitemap.

On WordPress

Yoast SEO and Rank Math automatically add correct canonical tags. If you've manually overridden a canonical in the SEO plugin settings, verify it's pointing to the right URL.

On Shopify

Shopify adds canonical tags automatically. Issues usually appear when collections have pagination or when product URLs appear in multiple collections. Check Online Store → Themes → edit theme code for custom canonical logic.
