Canonical URL Generator

Generate canonical link tags to prevent duplicate content issues.

About this tool

The Canonical URL Generator creates a canonical link tag that tells search engines which version of a page should be treated as the primary one. This prevents duplicate content issues caused by URL parameters, tracking codes, filters, or multiple URLs showing the same content.

Enter the preferred full URL and generate a ready-to-paste <link rel="canonical"> tag for your HTML <head>. If you’re managing crawl behavior, pair canonicals with a clean robots file using the Robots.txt Generator and submit your URLs via a sitemap from the XML Sitemap Generator. For permanent URL changes, use the .htaccess Redirect Generator instead.

How to Use This Tool

  1. Enter full page URL.
  2. Generate canonical tag.
  3. Insert into HTML head.
