Canonical URL Generator
Generate canonical link tags to prevent duplicate content issues. Enter your preferred URL and get the HTML tag ready to paste into your page head.
Duplicate content is one of the most common SEO problems websites face. When the same content is accessible through multiple URLs — such as with trailing slashes, query parameters, or HTTP/HTTPS variations — search engines may split ranking signals across all the duplicates, diluting your SEO performance.
The canonical URL tag (rel="canonical") tells search engines which version of a page is the primary one that should be indexed and ranked. Our Canonical URL Generator creates the proper HTML link tag that you can add to your page's <head> section.
Implementing canonical tags is essential for any website, especially e-commerce sites with filtered product views, blogs with paginated archives, and sites accessible via both www and non-www domains.
How to Use This Tool
- 1
Enter your preferred URL
Type the canonical version of the URL — the version you want search engines to index and show in search results.
- 2
Review the generated tag
The tool generates a <link rel="canonical"> tag with your URL. Make sure the URL is absolute (starts with https://).
- 3
Copy and implement
Add the generated tag to the <head> section of every version of the page. Each duplicate should point to the same canonical URL.
Best Practices
Always use absolute URLs (including the protocol and domain) in canonical tags, not relative paths.
Self-referencing canonicals are a best practice — every page should have a canonical tag pointing to itself, even if no duplicates exist.
Make sure the canonical URL returns a 200 status code. Pointing a canonical to a 404 or redirect can confuse search engines.
Use canonical tags consistently with your sitemap. Don't include non-canonical URLs in your sitemap.
If you syndicate content to other sites, ask them to include a canonical tag pointing back to the original on your domain.
SEO Tips
- Always use absolute URLs for canonical tags, not relative paths.
- Place the canonical tag in the <head> section of your HTML.
- Ensure canonical URLs use your preferred protocol (https://) and www preference.
- Self-referencing canonical tags (pointing to the same page) are recommended by Google.
- Canonical tags are hints, not directives — search engines may choose to ignore them.
