Canonical check
| Requested | https://smoothrecorder.com/blog?ref=newsletter |
| Final (after redirects) | https://smoothrecorder.com/blog?ref=newsletter |
| rel=canonical | https://smoothrecorder.com/blog |
| Consistent? | no ⚠ — canonical points elsewhere |
Self-referencing canonicals should match the final URL. A mismatch can deindex this page in favor of the canonical target.
Why it matters
Canonical is a hint, not a command
Google treats rel=canonical as a strong signal, alongside redirects, internal links and sitemaps. When those disagree, Google may pick a different URL.
Parameters create duplicates
Links with ?ref= or utm_ parameters create extra URLs for the same content. A canonical pointing at the clean URL consolidates them.
A wrong canonical removes pages
A template that points every page at the homepage, or at a staging domain, can drop whole sections from the index.
What it checks

Final URL

Consistency
Whether the canonical matches the final URL, ignoring a trailing slash.
