Moz Q&A is closed.
After more than 13 years, and tens of thousands of questions, Moz Q&A closed on 12th December 2024. Whilst we’re not completely removing the content - many posts will still be possible to view - we have locked both new posts and new replies. More details here.
How (or if) to apply re canonical tags to Shopify?
-
Anyone familiar with Shopify will understand the problems of their directory structure. Every time you add a product to a 'collection' it essentially creates a duplicate. For example...
- https://www.domain.com/products/product-slim-regular-bikini
may also appear as:
- https://www.domain.com/collections/all/products/product-slim-regular-bikini
- https://www.domain.com/collections/new-arrivals/products/product-slim-regular-bikini
- https://www.domain.com/collections/bikinis/products/product-slim-regular-bikini
- etc, etc
It's not uncommon to have up to six duplicates of each product.
So my question is twofold:
- Firstly, should I worry about this from an SEO point of view? I understand the desire to minimise potential duplicate content issues and also in focussing the 'juice' on just one page per product. But I also planned on trying to build the authority of the collection pages. If I request Google not to index the product pages which link off the collections, does this not devalue these collections pages?
- Secondly, I understand the correct way to fix these is using 'rel canonical' tags, but I'm not clear about HOW to actually do this. Shopify support has not been very helpful. They have provided two different instructions, so just added to the confusion (see below).
Shopify instruction #1: Add the following to the theme.liquid file...
<title><br />{{ page_title }}{% if current_tags %} – tagged "{{ current_tags | join: ', ' }}"{% endif %}{% if current_page != 1 %} – Page {{ current_page }}{% endif %}{% unless page_title contains shop.name %} – {{ shop.name }}{% endunless %}<br /></title>
{% if page_description %}{% endif %}
Shopify instruction #2: Add the following to each individual product page...
So, can anyone help clarify:
- The best strategic approach to this inherent SEO issue with Shopify (besides moving to another platform!)? and
- If 'rel canonical' tags is the way to go, exactly where and how to apply them?
Regards,
Murray

Howdy,
I assume that in your case it doesn't happen automatically. In this case you'll need to use an IF statements in the head/header file. Basically, it would be this:
IF current page url = url you want THEN display canonical tag with wanted url
Repeat that for all needed url and you are good.
If there are many of those, CASE might be better.

Good answer!
I have a question! If I just wanna add one or two canoncial tags on specific page(s), how I can do it on shopify coding?
-
How can I fix this problem with Shopify? Shopify does not seem like it is a problem. One of their solutions is to no index the other pages, but I want all the google juice and google love going to the main page.
Current Setup:
https://wrestlinggear.com/collections/wrestling-shoes rel canonical - https://wrestlinggear.com/collections/wrestling-shoes
https://wrestlinggear.com/collections/wrestling-shoes/accessory rel - https://wrestlinggear.com/collections/wrestling-shoes/accessory
https://wrestlinggear.com/collections/wrestling-shoes/adidas rel canonical - https://wrestlinggear.com/collections/wrestling-shoes/adidas
I want it like this:
https://wrestlinggear.com/collections/wrestling-shoes - rel canonical - https://wrestlinggear.com/collections/wrestling-shoes
https://wrestlinggear.com/collections/wrestling-shoes/accessory - rel canonical - https://wrestlinggear.com/collections/wrestling-shoes
https://wrestlinggear.com/collections/wrestling-shoes/adidas- rel canonical - https://wrestlinggear.com/collections/wrestling-shoes
Of course there are a lot more pages like this that I would like to rel cannoical back to the main collections pages.

Use tools like SEO Frog

Well, if it automatically doesn't work, then you gotta do it manually, right

-
I don't believe this is the answer. I have several other clients on Shopify who do not have goals for macro conversions, but we are seeing conversion data in GA.
Besides, I was always under the impression that if you have ecommerce enabled, it's better not to use goals for transactions as it might duplicate. Is this not the case?
-
I know how to check whether the code is there. But how do you check whether or not specific pages have been indexed by Google?
As far as I can see Google Search Console only reports on the number of pages indexed, not which pages have been indexed. Is there any way to get an actual list of indexed pages?
I know running a site: query will show up all the results, but I just want a list (eg CSV) of the URLs indexed.
-
Yes, I am. Here is a link with answers to your troubles: https://help.shopify.com/manual/reports-and-analytics/google-analytics/google-analytics-goals-and-funnels
-
Yes, it is supposed to. Try it, check it - it's pretty easy

-
Are you familiar with Shopify?
I have another issue where GA tracking code is not firing on the Thank_You page. I have double checked GA config with the GA implementation twice! But the problem seems to be with Shopify, since this page sites on their site (checkout.shopify.com) and they seem unable to fix it.
-
Thanks Dmitrii,
So will that one line of code fix the issue for ALL products and ALL collections?
-
Howdy.
Shopify does canonicals automatically. Basically all the collections products urls will have canonical to product url. Like this: https://www.domain.com/collections/all/products/product-slim-regular-bikini will have canonical to
https://www.domain.com/products/product-slim-regular-bikiniIf it doesn't happen for you automatically, simply insert this:
In the main theme.liquid file in the head section.

Rel canonical tag from shopify page to wordpress site page
We have pages on our shopify site example - https://shop.example.com/collections/cast-aluminum-plaques/products/cast-aluminum-address-plaque That we want to put a rel canonical tag on to direct to our wordpress site page - https://www.example.com/aluminum-plaques/ We have links form the wordpress page to the shop page, and over time ahve found that google has ranked the shop pages over the wp pages, which we do not want. So we want to put rel canonical tags on the shop pages to say the wp page is the authority. I hope that makes sense, and I would appreciate your feeback and best solution. Thanks! Is that possible?

Canonical Chain
This is quite advanced so maybe Rand can give me an answer? I often have seen questions surrounding a 301 chain where only 85% of the link juice is passed on to the first target and 85% of that to the next one, up to three targets. But how about a canonical chain? What do I mean by this:? I have a client who sells lighting so I will use a real example (sans domain) I don't want 'new-product' pages appearing in SERPS. They dilute link equity for the categories they replicate and often contain identical products to the main categories and subcategories. I don't want to no index them all together I'd rather tell Google they are the same as the higher category/sub category. (discussion whether a noindex/follow tag would be better?) If I canonicalize new-products/ceiling-lights-c1/kitchen-lighting-c17/kitchen-ceiling-lights-c217 to /ceiling-lights-c1/kitchen-lighting-c17/kitchen-ceiling-lights-c217 I then subsequently discover that everything in kitchen-ceiling-lights-c217 is already in /kitchen-lighting-c17 and I decide to canonicalize those two - so I place a /kitchen-lighting-c17 canonical on /kitchen-ceiling-lights-c217. Then what happens to the new-products canonical? Is it the same rule - does it pass 85% of link equity back to the non new-product URL and 85% of that back to the category? does it just not work? or should I do noindexi/follow Now before you jump in: Let's assume these are done over a period of time because the obvious answer is: Canonicalize both back to /ceiling-lights-c1/kitchen-lighting-c17 I know that and that is not what I am asking. What if they are done in a sequence what is the real result? I don't want to patronise anyone but please read this carefully before giving an answer. Regards Nigel Carousel Projects.

Changing title tags - any potential issues?
Hello all, I am planning to change the title tags throughout a site and am vaguely aware (perhaps wrongly!) that changing title tags across a site is a risk factor - can be a spam flag if changes (to a specific title tag) are implemented too regularly, for example. Would you change title tags across a site in one go, or implement changes gradually - to avoid any risk of upsetting Google. Do you have any insights/tips on the implementation of title tag changes?

Solution to Duplicate Pages within Shopify
Thanks in advance for your time and expertise. I am having issues with duplicate page content and titles on a client's Shopify subdomain. Examples below. Two questions: #1 How can I solve this issue? Do I block the duplicate pages from being crawled? With meta NoIndex? Establish the main page as the canonical version and stop obsessing? Other... #2 Is it a big concern or am I needlessly obsessing? Feels like a concern that needs to be addressed, but maybe not? Duplicate Page Content Examples: #1 URL: http://shop.shopvandevort.com #1 Duplicate URLs: http://shop.shopvandevort.com/collections/all; http://shop.shopvandevort.com/collections/all?page=1 #2 URL: http://shop.shopvandevort.com/collections/accessories #2 Duplicate URLs: http://shop.shopvandevort.com/collections/accessories; http://shop.shopvandevort.com/collections/types?q=Accessories Duplicate Page Title Examples: http://shop.shopvandevort.com/collections/vendors?q=For%20Love%20And%20Lemons http://shop.shopvandevort.com/collections/for-love-lemons http://shopvandevort.com/blog/tag/for-love-and-lemons/ http://shop.shopvandevort.com/collections/for-love-lemons?page=1 Thanks again for taking a look here, very much appreciated.

508 compliance vs good SEO re: Image alt tags
I'm currently in debate with our 508 compliance team over the use of alt tags on images. For SEO, it is best practice to use alt tags so that readers can tell what the image represents. However, they are arguing that these images should NOT have alt text as it doesn't add anything to the disability screen reader as the image text would be repetitive with the text on the page. I feel they are taking the "decorative" image concept in 508 compliance too far. It's intention is for images for bullets, etc that truly are decorative in nature and add no benefit to the reader. What is the communities thoughts on this? Have you ever run into scenario where 508 is attempting to ruin SEO? Usually the 2 play nicely.

Should you use a canonical tag on translated content in a multi-language country?
A customer of ours has a website in Belgium. There two main languages in Belgium: Dutch and French.
Intermediate & Advanced SEO | | Zanox
At first there was only a Dutch version with a .be extension. Right now they are implementing the French Belgium version on the URL website.be/fr. All of the content and comments will be translated. Also the URL’s will change from Dutch to French, so you've got two URL’s with the same content but in another language. Question: Should you use a canonical tag on translated content in a multi-language country? I think Google will understand this is just for the usability for a Multilanguage country. What do you guys think???0 -

Accidently added a nofollow, noindex tag and then...
Hey guys, My first post here and ironically highlights a ridiculously stupid mistake! Ok, here's the deal... I started building links to one of my new page on a fairly good, old site (DA = >35). Before starting to build links, I added fresh new content, and while doing that, I accidentally added a "nofollow" and "noindex" tag to the page! Guess what, google DID de-index the page ! So the questions is (and YES, I did change the meta tags): Will google re-index the page with some good linking? Will it treat the page as a new, fresh page even though it was present for over a year? I had already started link building to that page, and now technically the links are pointing to a page that does not exist in the index, so once it does get re-indexed, will Google FLAG it as having too many links? Would I be ranking it as a new page? Will its previous ranking (for very few keywords) will come back? Thanks and Regards, Amod
