In the SEO world, canonical tags are of indispensable importance in avoiding duplicate content by assisting search engines to comprehend a ‘preferred’ page version. You must set up canonical tags if you are operating a Shopify store and want to optimize your SEO strategy.

Follow this blog post, where we will take you step-by-step through adding canonical tags in Shopify and share some expert tips for maximum optimization.

But before that, let us first tell you what Canonical Tags are.

Let’s get started!

What are Canonical Tags?

What are Canonical Tags

Canonical tags, known as rel= “canonical” tags in HTML, are used by web developers to address duplicate content on the internet.

Duplicate content refers to the same or similar information appearing more than once on distinct URLs, thus making it difficult for search engines to identify the most relevant and authoritative page.

Website owners use canonical tags to tell search engines which version of a particular webpage they prefer when there are similar versions.

This can be done by specifying the preferred URL using this tag so that major search engines can determine whether it is original. It also helps to consolidate ranking signals and avoid any potential issues associated with replicated information.

How Do Canonical Tags Help SEO?

You can think of canonical tags as traffic cops for search engines. It’s like having two different addresses for the same post.

The search engines may find it difficult to know which one to list first. They inform the site crawler about the preferred version hence bringing together all strengths associated with SEO in the site.

This situation called content dilution happens when you have similar content spread across different URLs, which weakens their rankings.

When your entire website’s link value and user traffic are directed to a single URL, these tags function as laser pointers, improving the search ranking of your site as well as its general SEO performance.

Benefits of Employing Canonical Tagging for SEO


There are many benefits for your SEO when using canonical tagging, such as:

  • Syndicated Content: Canonical tags make syndicated content much easier to deal with. Whenever you syndicate material from one site to another, it’s important to have the engines still refer back to the source. Add the rel=” canonical” tag to your header, indicating which page you want to index.
  • Improved rankings: Whenever you give a search engine multiple versions of your web page or article, add canonical states that you want people to visit that specific page and boost the original ranking. 
  • Tracking: You can use canonical tags to track traffic from different sources. For instance, if you have two URL versions, one with www and another without it. This enables you to establish which version brings more traffic and, accordingly, optimize your site.
  • Regular search engine crawling: “Google will choose one URL as the canonical [main] version and crawl that, and all other URLs will be considered duplicate URLs and crawled less often,” Google says about crawling. So this means that unless you want Google to make this decision for you, include a canonical tag.

When to Use Canonical Tags in Shopify

Canonical tags are powerful tools, and they need to be used strategically. Here are a few common situations where these tags become necessary:

  • Paginated Product Listings: Although Shopify SEO Services automatically comes with canonical tags in product listing pages, you may still want to check for custom pagination implementation.
  • Filtered Product Views: This can make unique URLs when products are filtered by their category, color, or even size. Use canonical tags to point these variations back to the main product page.
  • Mobile-Specific URLs: Those having a different mobile URL structure can use canonical tags to allow the search engines direct access to the desktop version, which is the primary one from an SEO point of view. 
  • Similar Content on Different URLs: If you have content with informative blog posts or slightly different URLs, then a canonical tag can be used to identify the preferred version.
