Canonical URL
An HTML element that tells search engines which URL is the preferred version of a page when multiple URLs serve the same or similar content.
The canonical tag (rel="canonical") is placed in the HTML head of a page to consolidate ranking signals from duplicate or near-duplicate content. Without proper canonicalisation, PageRank can be split across multiple URLs, diluting ranking potential. Canonical URLs are especially important for ecommerce sites where product pages may be accessible via multiple URLs (filters, sort parameters, etc.).
