Canonical URL

Also called: rel='canonical'

A canonical URL is an HTML link element with the attribute rel='canonical' that tells search engines which version of a page is the authoritative or master copy. This prevents duplicate content issues arising from parameter URLs, print versions, or multiple URLs serving the same content.

Tip from Sanoop: Always implement self-referencing canonical tags on your primary pages. This guarantees Google knows which URL is the main one, even if UTM tracking parameters or HTTP/HTTPS variants are accessed.
