Privacy And Limitations

Canonical URL checks are performed locally in your browser. No input is uploaded.

  • This tool validates syntax only; it does not crawl your site to detect every duplicate cluster.
  • Canonicalization strategy still depends on internal links, sitemap entries, and redirect behavior.
  • A canonical tag is a strong hint, but search engines may choose a different URL in some cases.

FAQ

Should canonical URLs include query parameters?

Usually no, unless a parameterized URL is intentionally canonical for indexing.

Can canonical replace redirects?

Not fully. Redirects and canonicals solve overlapping but different URL consolidation tasks.

Must canonical use absolute URLs?

Absolute URLs are the safest approach across environments and parsing contexts.

Will canonical fix crawl budget alone?

Not by itself. Internal linking, parameter handling, and indexation quality still matter.

Is this a full SEO audit?

No. It generates valid canonical snippets and checks basic URL quality.
