What the result means

A canonical is a strong hint, not an automatic fix.

Search engines consider redirects, internal links, sitemaps, and duplicate content alongside the canonical tag. Conflicting signals need to be corrected together.

Use this when duplicate URLs or conflicting page versions may confuse search engines.

What it cannot prove

A canonical tag is one signal among several.

The check confirms the rendered tag and basic URL alignment on one page.
It does not compare every duplicate, redirect, internal link, or sitemap entry.
Search engines may ignore a canonical that conflicts with stronger site signals.
