Canonical URL Checker
Paste any URL and see exactly what canonical tag it serves — present, missing, self-referencing, or pointing at another page that could be suppressing your rankings.
How It Works
One URL, three seconds, a clear verdict on your canonical setup.
Enter the page URL
Paste the full URL of any public page, including https://.
We fetch and read the tag
The checker loads the delivered HTML and extracts the rel=canonical element.
Get the verdict and fix
See if the canonical is clean, self-referencing, or broken — with the exact fix.
What We Check
Every canonical issue that costs rankings, detected automatically.
Missing Tag Detection
Flags pages with no canonical at all, where Google must guess the preferred URL.
Self-Reference Check
Confirms the canonical points at the page's own URL with matching protocol and slash.
Cross-Domain Detection
Spots canonicals pointing at other domains that move ranking credit elsewhere.
Relative URL Flag
Warns on relative canonicals that are easy to resolve incorrectly across environments.
og:url Consistency
Checks the social share URL agrees with the indexed URL so signals don't split.
noindex Conflict
Detects pages carrying both a canonical and noindex — contradictory instructions.
Who Uses the Canonical URL Checker
Anyone who publishes content and needs to be sure the right URL gets the credit.
