Canonical Tag Generator
Generate a clean canonical link tag from any URL. Strips UTM and click IDs, forces https, and outputs the HTML tag plus HTTP header. Free SEO tool.
About the Canonical Tag Generator
Duplicate URLs quietly split your rankings: the same page reachable with UTM parameters, with and without a trailing hash, or over http and https looks like several pages to Google. A canonical tag fixes this by declaring one master URL. Paste any URL into this generator and it produces a clean canonical version plus the exact HTML tag to place in your page's head section.
The cleaning options handle the most common canonicalization mistakes automatically: tracking parameters like utm_source, fbclid and gclid are stripped, the fragment is removed (search engines ignore it anyway), the protocol is upgraded to https and the domain is lowercased. You also get the HTTP header form — the correct way to canonicalize PDFs and other non-HTML files.
Everything is generated instantly in your browser with nothing sent to a server, so you can safely process staging URLs and unlaunched pages.
How to Use the Canonical Tag Generator
- 1Paste the URL of the page version you want search engines to index.
- 2Toggle the cleanup options — https, tracking-parameter removal, fragment removal.
- 3Copy the generated HTML link tag into the <head> of every duplicate version of the page.
- 4For PDFs and files, use the HTTP header variant in your server config instead.
Frequently Asked Questions
What is a canonical tag?
A canonical tag (<link rel="canonical" href="…">) tells search engines which URL is the preferred version of a page when identical or very similar content exists at multiple addresses. It consolidates ranking signals onto one URL instead of splitting them.
Where do I put the canonical tag?
Inside the <head> section of the HTML page — on every duplicate version, all pointing to the same canonical URL. The canonical page itself should also carry a self-referencing canonical tag.
Should canonical URLs include UTM parameters?
No. Tracking parameters create infinite URL variations of the same content, which is exactly what canonicals exist to fix. This tool strips utm_*, fbclid, gclid and similar parameters automatically.
Is a canonical tag a redirect?
No — visitors stay on the URL they opened. It is only a hint for search engines about which version to index. If you actually want users moved to one URL, use a 301 redirect instead (and you then don't need canonicals between those two URLs).
Can I canonicalize a PDF?
Yes, but not with an HTML tag — PDFs have no <head>. Use the HTTP header this tool generates (Link: <url>; rel="canonical") in your server configuration.
