What is
Canonical Tag?
A link tag indicating the preferred URL when multiple URLs serve the same content.
By Anish· Founder · Vedwix
·Definition
A canonical tag (<link rel="canonical">) tells search engines which URL is the authoritative version of duplicate or near-duplicate content. It prevents duplicate-content issues from URL parameters, sorting, pagination, and HTTP/HTTPS variants. Misuse (canonicalizing to the wrong page) is a common SEO bug.
Example
/products/widget?color=blue and /products/widget?color=red both canonical to /products/widget — the variants don't compete with the canonical.
