Free Canonical URL Generator

Updated October 25, 2026

Free canonical URL tag generator: create HTML <link rel="canonical"> tags to consolidate duplicate URLs, UTM query parameters, and syndicated content.

<link rel="canonical" href="https://example.com/pricing" />

How to use Canonical URL Generator

Enter the single preferred, absolute HTTPS URL (https://www.example.com/page) that you want Google to index.

Copy the generated <link rel="canonical" href="..." /> tag.

Paste the tag inside the <head> of the canonical page (self-referencing) and any duplicate or parameterized variants.

When the same page can be loaded through multiple URLs—such as ?utm_source= tracking links, http:// vs https://, trailing vs non-trailing slashes, or e-commerce filter parameters—search engines split crawl budget and ranking signals across duplicates. Use this free canonical URL generator to output a clean, standards-compliant <link rel="canonical"> tag for your HTML <head>.

4 canonical tag rules that prevent Search Console indexing errors

  1. Always use absolute https:// URLs. Never write href="/page" inside a canonical tag.
  2. Never combine noindex with a cross-page canonical. Pointing a canonical to URL B while marking URL A noindex sends conflicting signals.
  3. Align your XML sitemap and internal links. Every URL listed in your XML sitemap must match the exact canonical URL character-for-character.
  4. Keep paginated pages self-canonical. Page 2 (/blog?page=2) should canonicalize to itself (/blog?page=2), not to Page 1, because Page 2 does not contain the same items as Page 1.

Canonical URL Generator FAQs

A canonical tag (<link rel="canonical" href="https://example.com/preferred-url" />) is an HTML <head> element that tells search engines which single URL version is the master copy when identical or near-identical content is accessible under multiple URLs.
