rel=canonical vs noindex for duplicate pages: don't bleed signals

Got near-duplicate or thin variants? Both keep them out of results, but one keeps your link equity.

rel=canonical consolidates ranking signals to the chosen URL and is a hint Google may override. noindex hard-drops the page and its accumulated signals go nowhere useful.

Pros (canonical): passes signals to the main version, keeps internal flow.
Cons (canonical): only a hint; Google can ignore it if pages differ too much.
Pros (noindex): definitive removal.
Cons (noindex): wastes any links/signals that page earned; directive, not hint.

Best for canonical: true duplicates (print versions, UTM variants, sort params) where you want signals merged.
Best for noindex: low-value pages that earned nothing and you want gone (internal search results, thin tag pages).
Using noindex on a page with backlinks throws equity away. 4.5/5 if matched to the right case.
