How to Fix a Missing Canonical URL
Search engines may see multiple URL variants as separate pages.
Recommended fix
Choose the preferred URL and expose it with rel=canonical.
This guide is designed to pair with a scanner report. Run a URL scan first, then follow the implementation steps.
Developer task
Add <link rel="canonical" href="https://example.com/preferred-url/"> to the head.
Implementation steps
How to apply this fix
- Decide the single preferred URL for the content, including protocol, host, and trailing-slash convention.
- Add <link rel="canonical" href="https://example.com/preferred-url/"> to the document head, using an absolute URL.
- Make sure each variant (www/non-www, http/https, query params) points to the same canonical.
- Re-scan and confirm the canonical resolves to a single indexable URL.
Verify
Re-run the URL scan after deploying the change to confirm the issue clears and the Themerella Score updates.
