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.
