What is canonical tag ?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>What is canonical tag? The Canonical tag in SEO is an HTML code element that is basically used to indicate the version of webpage you want and should appear on search engine result page when user makes a query.<\/p>\n<p>Canonical tags have been in existence since 2009, making them a well-established solution for any canonical issue.<\/p>\n<p>Canonical tags were developed collaboratively by Google, Microsoft, and Yahoo. Their primary purpose was to offer website owners a simple and efficient method to address problems related to duplicate content.<\/p>\n<p>At times a <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/9781119127444.ch5#:~:text=Canonical%20problems%20are%20those%20having,method%20of%20separation%20of%20variables.\" rel=\"nofollow noopener\" target=\"_blank\">canonical error<\/a> occurs where multiple version of the same content exist but with different URLs. Such canonical issue may effect you webpage indexing and ranking.<\/p>\n<p>The Canonical tag is primarily employed to address duplicate content issues that can arise on the internet due to various reasons such as different URLs for the same content, HTTP and HTTPS versions, session IDs, printer-friendly pages, etc.<\/p>\n<p>But here&#8217;s the catch: canonical tags work flawlessly only if you understand how to implement them effectively!<\/p>\n<p>In this blog, we will learn about what is a canonical tag. Also, we will know why it is <a href=\"https:\/\/nidmm.in\/seo-training-course.php\">important for SEO<\/a> and how to implement canonical.<\/p>\n<p>Also read- <a href=\"https:\/\/nidmm.in\/blog\/9-important-technical-issues-matters-in-seo\/\">9 Important Technical Issues that Matters in SEO<\/a><\/p>\n<h2 style=\"color: #252525;\"><span class=\"ez-toc-section\" id=\"What_is_the_structure_of_a_canonical_tag\"><\/span>What is the structure of a canonical tag?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A canonical tag is represented by &#8220;rel=canonical&#8221; in HTML code, serves as a valuable tool for identifying the primary version of duplicate, near-duplicate, or similar web pages.<\/p>\n<p>The canonical tag typically appears in the &lt;head&gt; section of an HTML page and follows this format:<\/p>\n<p>&lt;<span class=\"hljs-name\">link<\/span> <span class=\"hljs-attr\">rel<\/span>=<span class=\"hljs-string\">&#8220;canonical&#8221;<\/span> <span class=\"hljs-attr\">href<\/span>=<span class=\"hljs-string\">&#8220;https:\/\/www.example.com\/preferred-url&#8221;<\/span>&gt;<\/p>\n<p>The &#8220;href&#8221; attribute should contain the URL of the webpage you want to appear on search results. When a search engine encounters this tag, it understands that the specified URL is the one to be considered for ranking and indexing purposes, while treating the other versions as duplicate.<\/p>\n<p>Simply apply canonical tag when you have identical or similar content accessible through various URLs, implementing canonical tags allows you to indicate which version should be considered the main one and indexed accordingly.<\/p>\n<p>By implementing the canonical tag properly you can prevent potential SEO issues caused by content duplication. It also helps in ensuring that the correct version of a page appears in search engine results, improving the overall user experience.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_are_canonical_tags_important_for_SEO\"><\/span>Why are canonical tags important for SEO?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Now you must have understood what exactly is canonical tag in SEO.
