¿Por qué importa esto?
Canonical tags tell Google which version of a page is the "real" one when duplicate content exists. Without it, Google gets confused by URL variants (e.g. with/without www, trailing slash, UTM parameters).
¿Cómo se soluciona?
Add a self-referencing canonical tag to every page. Make sure it contains the absolute URL and is consistent with HTTPS and www/non-www choice. Also use it for paginated content.
