Canonical URL — Prevent Duplicate Content
A canonical URL is declared using the <link rel="canonical"> tag in the HTML head. It tells search engines which version of a page is the authoritative "original" when the same content is accessible at multiple URLs. Common causes of duplicate content: URL parameters (tracking, sorting, filtering), www vs non-www, HTTP vs HTTPS, paginated content, and printer-friendly page versions. Without canonicals, search engines might split your ranking signals across multiple duplicate pages.
