Enter any public website URL below to inspect the canonical link tag and understand whether the page points to the correct preferred URL.
Review the canonical tag and improve how search engines understand the preferred URL version of a page. Good canonical implementation helps reduce duplicate content confusion and supports cleaner indexing signals.
This tool is useful for SEO professionals, site owners, agencies, eCommerce stores, publishers, and developers who want stronger duplicate content handling and better technical SEO clarity.
Canonical tags help indicate which version of a page should be treated as the preferred URL. This is especially useful when similar or duplicate pages exist due to parameters, filters, multiple paths, or technical duplication.
This free Canonical Tag Checker scans the canonical link element and helps you review whether the page is using it correctly and whether it points to the expected version.
Without a clear canonical signal, search engines may struggle to identify the preferred URL among duplicates. Proper canonical usage helps consolidate relevance and reduces confusion between similar pages.
Enter your page URL and review whether a canonical tag exists. Check if the canonical points back to the same page or to another intended preferred URL. If a page should be self-canonical, the canonical should usually match that page.
The best canonical implementation is usually clear, intentional, and absolute. If a canonical points somewhere unexpected, review whether that is a deliberate SEO decision or an accidental technical issue.
