Canonicalization is a crucial SEO technique used to address duplicate content issues by specifying the preferred version of a webpage when multiple versions exist. This helps search engines understand which URL to index and rank, thus consolidating link signals and avoiding potential penalties for duplicate content.

Example Concept: Canonicalization involves using the "rel=canonical" link element in the HTML head of a webpage to indicate the preferred URL version to search engines. This ensures that search engines consolidate ranking signals to the canonical URL, reducing the risk of duplicate content issues and improving SEO performance.

Additional Comment:

Canonical tags should be implemented on pages with similar or identical content.
Ensure that the canonical URL is accessible and returns a 200 status code.
Canonical tags are a hint, not a directive, so search engines may choose to ignore them if not implemented correctly.
Use canonical tags in conjunction with other duplicate content management strategies, like 301 redirects or parameter handling.
