Ready when you are
Paste a page URL to diagnose canonical configuration
The scan checks the canonical tag, resolved page URL, and host alignment, then surfaces what changed from indexing defaults.
- Canonical status
- Canonical target URL
- Resolved page URL
- Alignment evidence
- 01
Enter one complete page URL.
- 02
Run the check and confirm a canonical tag was found.
- 03
Compare the canonical URL with the page you expect search engines to index.
- 04
Investigate redirects, parameters, or templates when the URLs do not align.
What the result means
A canonical is a strong hint, not an automatic fix.
Search engines consider redirects, internal links, sitemaps, and duplicate content alongside the canonical tag. Conflicting signals need to be corrected together.

Scope of this check
Know what the result can tell you.
What it checks
- Canonical tag status
- Preferred canonical URL
- Basic URL alignment findings
What it cannot prove
A canonical tag is one signal among several.
- The check confirms the rendered tag and basic URL alignment on one page.
- It does not compare every duplicate, redirect, internal link, or sitemap entry.
- Search engines may ignore a canonical that conflicts with stronger site signals.
Questions before you act
Canonical Tag Checker questions
01What should a canonical tag point to?
It should identify the preferred indexable version of the page. On a unique page, that is often the page own clean URL.
02Is a missing canonical always an SEO problem?
Not always, but explicit self-referencing canonicals reduce ambiguity and make template behavior easier to verify.
03Why would Google ignore a canonical?
Redirects, internal links, sitemaps, duplicate content, or page quality may signal that another URL is the better representative.
