Canonical URL Tag Generator
Output a rel=canonical tag for the exact HTTPS URL you want indexed. Use it on duplicates, not as a substitute for redirects.
Place this tag inside the <head> of your HTML document to tell search engines which URL is the preferred version of this page.
What this tool does
Duplicate URLs dilute SEO signals — canonical tags tell search engines which version to index.
Essential for parameterized URLs, www/non-www variants, and syndicated content.
How to use it
- 1
Enter the preferred canonical URL for your page.
- 2
Copy the generated link rel=canonical HTML tag.
- 3
Paste into your page head or CMS SEO settings.
Implementation notes
Canonical must be absolute URLs with https. Self-referencing canonicals on unique pages are best practice.
Canonical is a hint — strong duplicates may still require 301 redirects.
Tips
- Add canonical tags in CMS SEO plugins or theme head templates.
- Audit canonicals after site migrations.

Frequently asked questions
When do I need a canonical tag?▼
When the same content is accessible at multiple URLs — parameters, www vs non-www, HTTP vs HTTPS.
Can I canonicalize to a different domain?▼
Cross-domain canonicals are supported but use carefully — Google treats them as strong hints, not redirects.
