What is Canonical Tag?
Canonical tag is also known as a canonical link, it’s an HTML element that helps webmasters and website owners to prevent any duplicated content. This is done by giving content a unique canonical URL. In reality, canonical tag will let you tell search engines such as Google that there are several links on the website which share the same URL. Therefore, you can use pages with the same content but a different URL without worrying about your SEO.
Using canonical tag is very simple and easy to understand. When you have duplicated content on your website you will define a canonical tag for them and tell search engines to use them. By this way, search engines such as Google will understand which version of content should be displayed in the search results. In other words, canonical tag or canonical URL is the link that you want people to see in Google’s results page.
How to enhance SEO using Canonical Tags?
Using canonical tag for similar links will improve your SEO because search engines know where the same pages should be directed to. Let us explain with an example, look at the URLs below:
You may think these URLs are the same but search engines see them differently. Search engines such as Google look at every link separately. If Google sees the same content in several different links, it’s highly likely that Google will think you have copied your content from other sources and there has been plagiarism.
Therefore, if Google comes across such links and website it will have a tremendous impact on your SEO and your ranking will drop dramatically. However, if you use the canonical tag you can avoid this issue and have multiple links for your content.
Based on what we talked about, we recommend adding a canonical tag in your SEO strategies.
How to set Canonical URL?
Now that we know how useful the canonical link is to improve your SEO, let’s talk about how to use it properly.
Imagine you have two pages with two exact content however, some paragraphs are a little different. Assuming that both of these contents are very valuable and they will provide your website with good traffic. You must select one of them and use a canonical tag for it so you don’t face any SEO problems.
For example, imagine the URLs below are similar and you want to use a canonical tag.
you must use canonical tag (rel=canonical) for one of them. Pick the most valuable URL, if the content of both is the same, pick the URL with the most traffic and backlink.
Now you have to direct the page you didn’t select to the page you selected for canonical. You can do this with the help of the HTML code below. For example, if #1 from the example above is selected for canonical tag, you have to add the code below in the <head> of the second URL:
<link rel=”canonical” href=”http://example.com/wordpress/seo-plugin/” />
By using this very simple method, the content of the first page will be used as the main page/content.

Using canonical tag for self-referencing
In the example given to set canonical URL, we directed a non-canonical page to a canonical page, but does a page need a canonical tag for itself?
