How many websites pass the Canonical Origin check?
Based on 496 audited sites · Updated 2026-07-16
95% confidence interval: 21.4%–29%
Why This Matters
LLM Discoverability
A canonical that points to a different domain or subdomain is interpreted as a cross-domain redirect signal by AI crawlers; incorrect canonicals can attribute page content to the wrong entity entirely.
SEO Impact
Cross-origin canonical mismatches are a common cause of Google ignoring the canonical directive, reverting to treating both URLs as independent pages and splitting link equity.
What To Do Next
75% of audited sites need attention on canonical origin (372 of 496 sites are warning or failing).
- Prioritize canonical origin on templates that create many URLs, because one template fix can improve a large share of html extractability & main content clarity.
- After changing the page, re-run the audit and compare the observed value for this check instead of relying on visual inspection alone.
- Use the 25% pass rate as a benchmark: if your site fails here, passing the check moves it closer to the visible majority of crawlable, AI-readable pages.
