URL canonicalization

URL canonicalization is the process of standardizing different versions of a webpage URL to a single, preferred format. Search engines and browsers might see multiple URLs pointing to the same content, which can cause confusion and dilute search rankings. By selecting a primary version—known as the canonical URL—and guiding all links and references to it, website owners help ensure consistency. This improves search engine understanding, avoids duplicate content issues, and enhances the site's SEO performance.
