About This Check

The canonical URL tells search engines and LLM crawlers what the preferred URL is for this page, which helps consolidate signals and avoid duplicates.

Why This Matters

LLM Discoverability

The canonical tag signals to AI crawlers which URL is the authoritative version; without it, citation links may point to duplicate or parameterised variants, diluting traffic back to the intended URL.

SEO Impact

Canonicalisation consolidates PageRank from duplicate URLs onto the preferred version; without proper canonicals, link equity is split across variants and total ranking power is reduced.

What To Do Next

31% of audited sites need attention on canonical (185 of 596 sites are warning or failing).

Prioritize canonical 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 69% 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.
