How to use the Canonical Checker results

Canonical tags help indicate the preferred URL when the same or very similar content can be reached through multiple addresses. This is especially useful for parameter URLs, alternate paths, and other duplicate variations. A canonical is a signal rather than a substitute for clean site architecture, so also check redirects and internal links when duplicates appear. The preferred URL should normally be indexable, accessible, and consistent with the version you want search engines to treat as primary.
