Free canonical tag generator
Clean up any page URL and get a correct rel canonical tag or HTTP header in one click.
Result
The free canonical tag generator runs in your browser, needs no sign-up and never sends what you type anywhere.
Quick answer
This canonical tag generator takes any page URL, normalizes the protocol, www, trailing slash and tracking parameters, and outputs a rel canonical link tag or HTTP Link header. Rule of thumb: use one absolute HTTPS URL that returns 200, matches your internal links and sitemap, and place the tag in the head of every duplicate and the canonical page.
What is a canonical tag generator?
A canonical tag generator is a tool that builds the link rel="canonical" element telling search engines which URL is the preferred version of a page. It rewrites the URL you enter into one consistent form (protocol, host, path and needed parameters only) and wraps it in the HTML tag or the HTTP header used for PDFs.
How do you use the Canonical Tag Generator?
- Paste the page URL, including any parameters you see in the browser.
- Choose your site-wide preferences for HTTPS, www and the trailing slash.
- Decide whether to strip tracking parameters only or all query parameters.
- Check the normalized URL and the list of changes, then copy the tag or header.
- Add the tag inside the head of the page and its duplicates, and confirm the URL returns 200.
Should a page have a self-referencing canonical?
Yes, adding a canonical tag that points to the page itself is recommended. It protects against duplicates created by tracking parameters, session IDs or mixed case URLs, because every variant then points back to one clean URL. Google suggests it in its guide to specifying a canonical URL.
Is the canonical tag a directive?
No, rel canonical is a strong signal, not a directive, so Google can pick a different canonical if other signals disagree. Redirects are the strongest signal, canonical tags next, and sitemap inclusion weaker. Make internal links, sitemaps, hreflang and redirects all point to the same URL so the signals agree.
Should canonical URLs be absolute or relative?
Use absolute URLs such as https://example.com/page/. Relative paths can be misread when pages are copied to staging or served on another host, which can point Google at the wrong site. This tool always outputs a full URL.
Quick reference
| URL variant | Example | Typical canonical choice |
|---|---|---|
| Protocol | http:// and https:// | https:// |
| Host | example.com and www.example.com | One version, matching your redirects |
| Trailing slash | /blog/seo and /blog/seo/ | One version, matching your internal links |
| Tracking parameters | ?utm_source=newsletter | Removed |
| Content parameters | ?page=2 or ?color=red | Often kept when the content differs |
| Index file | /blog/index.html | /blog/ |
Worked example
Example
Example: http://Example.com/blog/seo-tips/index.html?utm_source=newsletter&page=2#comments with HTTPS, no www, trailing slash and tracking only selected becomes https://example.com/blog/seo-tips/?page=2. The tool drops utm_source and the fragment, lowercases the host, removes index.html and keeps page=2 because it changes the content.
Frequently asked questions
Where do I put the canonical tag?
Place the link rel="canonical" element inside the head section of the HTML. Google ignores canonical links found in the body, and invalid HTML earlier in the head can push it out. For PDFs and other non-HTML files, send the canonical as a Link HTTP header instead.
Can I use canonical tags across domains?
Yes. A cross-domain canonical is useful when the same article is syndicated to another site. The partner page points its canonical to your original URL. Google treats it as a hint, so the original should be the most complete version and linked from the copy.
Should paginated pages canonical to page 1?
No. Each paginated page, such as ?page=2, usually has different content and should have a self-referencing canonical. Pointing every page to page 1 can stop Google from finding products or articles linked only from deeper pages.
Can I combine canonical with noindex?
Avoid it. Noindex says do not index this page, while canonical says another page is the main version, so the signals conflict. Pick one: canonical for duplicates you want consolidated, or noindex for pages you never want in search.
Does uppercase in a URL matter for canonicals?
The host name is not case sensitive, but the path usually is, so /Blog/ and /blog/ can be different URLs. This tool always lowercases the host and only lowercases the path if you tick the option. Match the exact case your server uses.
Is this canonical generator private?
Yes. The URL you type is processed only in your browser with JavaScript and is never sent to a server. The tool checks format only, so also confirm with the URL Inspection tool in Search Console which canonical Google selected.
