Canonical Tag

Quick Definition

The canonical tag (<link rel='canonical'>) tells search engines which URL is the master version when multiple URLs serve similar or identical content.

In context

Canonical tags consolidate ranking signals to the canonical URL. Common uses: pagination, faceted navigation, tracking parameters, and HTTP/HTTPS or www/non-www variants. Self-referencing canonicals (a page canonicalizing to itself) are best practice.
