Multiple Canonical Tags on Single Page

More than one canonical tag found on a single page, causing conflicting deduplication signals to search engines.

By Seoxpert Editorial · Published

Why it matters

When a page has multiple canonical tags, search engines cannot determine which URL is preferred, so they may ignore all canonicals. This can result in duplicate content issues, diluted link equity, and unpredictable indexing behavior.

Impact

If unresolved, the page may suffer from duplicate content penalties and reduced search visibility.

How it's detected

Automated crawlers scan the HTML and flag pages containing more than one <link rel="canonical"> element in the head section.

Common causes

  • •Multiple SEO plugins or modules injecting canonical tags
  • •Theme templates hardcoding a canonical tag while plugins add another
  • •Third-party scripts or tag managers inserting additional canonical tags
  • •Manual addition of canonical tags without auditing existing ones

How to fix it

Review your page's HTML source to ensure only one <link rel="canonical"> tag is present. Audit your CMS plugins, theme files, and any third-party scripts for duplicate canonical injections. Remove or disable redundant sources so only a single canonical tag remains per page.

Code examples

Problem: Multiple canonicals

<head>
  <link rel="canonical" href="https://example.com/page-a" />
  <link rel="canonical" href="https://example.com/page-b" />
</head>

Fix: Single canonical

<head>
  <link rel="canonical" href="https://example.com/page-a" />
</head>

FAQ

What happens if my page has two different canonical tags?

Search engines may ignore both tags, leaving the page without a clear canonical signal and risking duplicate content issues.

How can I find out which plugin or script is adding extra canonical tags?

Inspect your page's HTML source and disable plugins or scripts one by one to identify which is injecting the additional canonical tag.

Is it ever okay to have more than one canonical tag on a page?

No, each page should have exactly one canonical tag to provide a clear deduplication signal to search engines.
