A canonical URL tells search engines which version of a webpage is the primary one when multiple versions exist. It prevents duplicate content issues that can hurt SEO rankings. For instance, if a page is accessible at both /product?id=1 and /product/shoes, the canonical tag points to the chosen version. This improves consistency in search results, consolidates link equity, and ensures users land on the right page. Canonical tags are key for large or e-commerce sites.
