Canonical Tag Checker

  • Browser-based
  • No signup

Enter a page URL and paste HTML—or fetch the page when allowed—to locate the canonical link tag and compare it with the inspected URL.

100% Client-Side

Your data never leaves your computer.

How to use this tool

1. Enter the page URL you want to audit. 2. Paste page HTML or fetch the document when CORS allows. 3. Review the canonical href, whether it is absolute, and how it compares to the inspected URL. 4. Fix missing or conflicting canonicals in your CMS or template.

Worked example

Example: https://example.com/blog/post may show a canonical of https://example.com/blog/post/ (trailing slash)—compare both URLs to catch duplicate-content signals before indexing.

How it works

Enter a page URL and paste HTML—or fetch the page when the browser allows it—to find the canonical link tag and compare it with the inspected URL. Useful for spotting missing, relative, or cross-URL canonicals.

Limitations

Page HTML is fetched from your browser when you do not paste source HTML. Many sites block cross-origin requests—paste HTML for reliable results.
