Canonical Tag Generator

Paste a URL and get a clean, copy-ready rel=canonical link tag to tell search engines which version of a page is the original.

Use a self-referencing canonical: most pages should point to their own absolute URL. Add exactly one canonical tag inside the <head> of the page it refers to, and always use the full address including https://.
— What it does

The Canonical Tag Generator is a free tool that turns any page URL into a valid rel=canonical link element you paste into the head of your HTML. A canonical tag tells Google and other search engines which URL is the authoritative version of a page, consolidating ranking signals and preventing duplicate-content issues. It validates and lightly normalizes the URL, and runs entirely in your browser so nothing is uploaded.

  • Outputs a ready-to-paste rel=canonical link tag from any URL.
  • Validates the URL and adds the protocol if you forget it.
  • Built-in guidance on self-referencing canonicals and common mistakes.
  • Runs entirely in your browser — nothing is uploaded to any server.

How to use it

1

Enter the canonical URL

Paste the full, preferred URL of the page you want search engines to treat as the original.

2

Copy the generated tag

The tool builds a valid <link rel="canonical"> element and flags any problems with the URL.

3

Add it to your <head>

Place the tag inside the <head> of the page it points to, ideally as a self-referencing canonical.

Frequently asked

What is a self-referencing canonical tag?
A self-referencing canonical is a rel=canonical tag on a page that points to its own URL. It is a recommended best practice because it removes ambiguity about the preferred version, even when there are no duplicates.
Should the canonical URL be absolute?
Yes. Always use the full absolute URL including the protocol, like https://example.com/page. Relative paths can be misinterpreted, so this generator outputs an absolute URL.
Where do I put the canonical tag?
Place a single canonical tag inside the <head> section of the HTML document. Having more than one canonical tag on a page causes search engines to ignore all of them.
Is my URL sent anywhere?
No. The tag is built locally in your browser with JavaScript. Your URL is never uploaded to a server and nothing is stored.
