What is a canonical URL?

A Canonical URL is a web address specified by a site that it wants search engines to index. It resolves the issue of duplicate content by designating a primary version of a given page.

Imagine you have multiple versions of the same page (for example, pages with different settings). Search engines may treat them as duplicate content, which can harm your SEO. By using a canonical URL, you clearly indicate which version should be considered.
