A **canonical tag** (rel=canonical) is an essential HTML element that helps webmasters prevent duplicate content issues. It tells search engines like Google which version of a URL is the **preferred version** to index when multiple URLs contain identical or very similar content. By specifying a **canonical URL**, you consolidate signals (like **link equity**) for all duplicate versions onto a single, authoritative page, improving your site’s **SEO performance** and avoiding **duplicate content penalties**. This ensures search engines rank the correct and most valuable page.
