What is a Canonical Tag?

A canonical tag (`rel="canonical"`) is an HTML snippet that tells search engines which version of a URL is the "master" copy.

Solving Duplicate Content

If you have the exact same content on `website.com/shirts` and `website.com/shirts?color=red`, Google gets confused about which one to rank. A canonical tag points the `?color=red` page back to the main `/shirts` page, consolidating your SEO ranking power into one single URL.
