Canonical URL Checker
Paste HTML and see its canonical link tag: whether one exists, whether there are multiple (a problem), and whether it is an absolute URL. A canonical tag is a hint to search engines about the preferred version of a page, not a redirect and not a guarantee.
A canonical tag is a hint to search engines, not a redirect and not a guarantee.
What this tool cannot do
Pasted HTML only. It cannot fetch a live URL, and it cannot confirm that Google will honour the canonical you set.
How to use it
- Paste the page's HTML.
- Click Check canonical.
- Fix missing, multiple or relative canonicals, then re-check.
Frequently asked questions
Should the canonical be absolute or relative?
Absolute, including https:// and the full domain, is the safest form.
Does a canonical tag redirect visitors?
No. Visitors still land on the page they requested; the tag only hints to search engines which version to prefer.
