Tool
Canonical Checker
Inspect whether a page exposes a canonical tag and whether it points to the right URL.
Canonical issues can dilute rankings, confuse indexing, and make duplicate URLs harder to control.
Expected outcome
A healthy page usually has one canonical tag pointing back to its preferred self URL.
What the report highlights
It highlights missing tags, relative canonical values, cross-domain references, and self-reference mismatches.
