Shopify SEO: Fix Pagination Canonical Links

Canonical issues on Shopify are easy to miss, but that does not make them harmless. From pagination and product variants to apps and theme quirks, it is surprisingly common for Shopify stores to send mixed signals to search engines without realising it. The result can be duplicate URLs, wasted crawl budget, and key pages failing to perform as well as they should.

For eCommerce brands, that can mean weaker organic visibility and missed revenue. The good news is that many of these issues are not especially difficult to fix once you know where to look and what is causing them.

Shopify SEO: Fix Pagination Canonical Links

Shopify Pagination Explained

Paginated pages on Shopify are simply pages split into multiple parts to make large collections, blog archives, or product listings easier to browse. Rather than loading every product or article on a single URL, Shopify breaks them across a series of pages, usually accessed via parameters such as ?page=2, ?page=3, and so on.

This is most commonly seen on collection pages where there are too many products to sensibly display at once. For users, pagination helps keep pages cleaner and easier to navigate. For search engines, though, it can create complications if those paginated URLs are not handled properly. If canonical tags point to the wrong version, or all paginated pages are consolidated incorrectly, Shopify can end up sending mixed signals about which pages should be crawled, indexed, and given value.

That is why pagination is not just a usability feature. It also has SEO implications, especially for larger Shopify stores where collections span multiple pages.

The SEO Impact of Shopify Pagination

Pagination can affect SEO by changing how search engines crawl, understand, and prioritise your collection pages. On larger Shopify stores, paginated URLs often sit behind collection pages with dozens or even hundreds of products, so getting them wrong can make it harder for Google to properly discover deeper products and category content.

If Shopify pagination is not handled properly, search engines can be sent conflicting signals about which pages matter most. That can lead to issues such as duplicate content, diluted ranking signals, and valuable product pages that are harder to reach via internal links. In some cases, it can also mean that paginated URLs are crawled inefficiently, which is far from ideal if you want Google to spend its time on your most important pages.

The canonical setup plays a big part here. If paginated pages all point back to page one, for example, it can suggest that the deeper pages are not important in their own right. While page one of a collection will usually carry the most SEO value, the pages that follow still help search engines access more products and understand the full depth of the collection. That is why pagination is not just a technical detail. It can directly impact crawl efficiency, indexation, and how well your store’s key pages perform in search.

How to Fix It With Canonicalization

By default, Shopify often uses self-referencing canonicals on paginated collection URLs. So, if you have a URL such as /collections/shoes?page=2, Shopify may output that exact URL as the canonical.

For pagination, that is not always ideal. In many cases, it makes more sense for paginated collection pages to point back to the main collection URL instead. So, /collections/shoes?page=2 would have a canonical URL of /collections/shoes, helping reinforce the primary version of the collection.

The good news is that this is usually a straightforward fix and can be handled with a small change to your Shopify theme code.

Step 1

Step 2

From the left-hand menu, click Online Store.

Step 3

Next to the Customise button, click the three dots.

Step 4

Select Edit code from the dropdown menu.

Step 5

Open the theme.liquid file.

Step 6

In the code editor, look for this line:

Step 7

Replace it with the following code:

{% if template contains ‘collection’ %}
<link rel=”canonical” href=”{{ shop.url }}{{ collection.url }}” />
{% else %}
<link rel=”canonical” href=”{{ canonical_url }}” />
{% endif %}

Step 8

Click Save in the top-right corner.

Step 9

Once saved, check that your paginated collection URLs are now pointing their canonical tags back to the main collection page.

That version aligns better with the earlier sections because it avoids repeating too much of the SEO explanation and gets to the actual fix faster.

Shopify pagination canonical issues are not the most obvious SEO problem to spot, but they can cause unnecessary confusion for search engines and weaken the signals you want your collection pages to send. The upside is that, in many cases, the fix is relatively simple and can be implemented quickly once you know where to look.

For stores with large collections, getting this right helps keep your canonical setup cleaner and reinforces the main pages you actually want search engines to focus on. It is a small technical change, but one that can help create a stronger foundation for your Shopify SEO.
