Result model

Canonical Checker result model

A clean canonical result confirms that one preferred URL is declared and that it matches the intended page.

Severity ladder

Every report separates blockers, warnings, and healthy confirmations.

This is the reporting model behind the live tools, so operators know what to fix first instead of reading a flat list.

Critical

Fix these before relying on the current setup for monetization, indexing, or language targeting.

Warning

The page or file is reachable, but there is still technical risk worth reducing quickly.

Healthy

Public signals look aligned. Keep this state stable while you scale content or ads.

Signals included

  • Existence and count of canonical tags
  • Absolute URL format of the canonical value
  • Self-reference or cross-domain mismatch warnings

Operator actions

  • Keep only one canonical tag per page.
  • Point the canonical to the exact preferred URL, including protocol and host.
  • Avoid mixing staging, alternate domains, or temporary URLs.
01

Run the public check

Use the live checker to see what is publicly reachable and technically visible today.

02

Fix the highest severity first

The result model is intentionally ordered so blockers come before informational clean-up.

03

Re-run after deployment

These tools are built for before-and-after verification, not one-time screenshots.
