Canonical URL Checker
Verify the canonical URL declared by any public page and compare it with the final destination.
Inspect canonical URL declarations
The audit extracts rel=canonical links, counts duplicate declarations, compares the first canonical with the final URL, and reports the HTTP response.
Interpret the result
The result shows whether the page declares one clear preferred URL and whether that declaration is self-referencing.
Catch common problems
Missing tags, multiple canonicals, redirected targets, or a canonical that points to an unintended host can split consolidation signals.
How to interpret canonical URL declarations
The result shows whether the page declares one clear preferred URL and whether that declaration is self-referencing. A canonical is a search-engine hint, not a directive; this check cannot confirm which canonical a search engine ultimately selects.

- The audit extracts rel=canonical links, counts duplicate declarations, compares the first canonical with the final URL, and reports the HTTP response.
- Missing tags, multiple canonicals, redirected targets, or a canonical that points to an unintended host can split consolidation signals.
- Keep one intentional absolute canonical, make the target reachable and indexable, and align internal links and sitemap URLs with it.
