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.

Should I disable the indexing of tags in Wordpress?
Hi, I have a client that is publishing 7 or 8 news articles and posts each month. I am optimising selected posts and I have found that they have been adding a lot of tags (almost like using hashtags) . There are currently 29 posts but already 55 tags, each of which has its own archive page, and all of which are added to the site map to be indexed (https://sykeshome.europe.sykes.com/sitemap_index.xml). I came across an article (https://crunchify.com/better-dont-use-wordpress-tags/) that suggested that tags add no value to SEO ranking, and as a consequence Wordpress tags should not be indexed or included in the sitemap. I haven't been able to find much more reliable information on this topic, so my question is - should I get rid of the tags from this website and make the focus pages, posts and categories (redirecting existing tag pages back to the site home page)? It is a relatively new websites and I am conscious of the fact that category and tag archive pages already substantially outnumber actual content pages (posts and news) - I guess this isn't optimal. I'd appreciate any advice. Thanks wMfojBf

Putting Dates In Title Tag
Hi, I have a site were I write previews for sports match ups. I notice when I don't put the date in the title I rank much better for specific keywords. I also noticed that most people don't really put in the date when they do the search anyways, especially since google does a good job of showing the most recent pages anyways. The only reason I continue to put the date is because of this whole idea of not having page titles that are duplicate. So many of our games will be Team A vs Team B Preview, and Im worried that the term "preview" will become so repetitive that google may not like it. Any tips or ideas on how to approach this issue best? Thanks!

Best Practices for Homepage Title Tag
Hi, I would like to know if there is any update about the best practices for the homepage title tag. I mean, a couple of years ago, it was still working placing main keywords in the homepage title tag. But since the last google SERP update, the number of characters that are being shown were reduced, and now we try to work with 55 and 56 characters. That has reduced our capacity of including many keywords on the title tag. Besides, search engines are smarter now to choose the correct inner page to show in SERP. But I am wondering if the Homepage Title should have a branded orientation or should include main keywords, cause it is still working that strategy. I would appreciatte any update in this issue. Thank you!

Does a UTM tag influence the linkvalue?
Will Google value a link with a UTM tag the same as a clean link without a UTM tag? I should say that a UTM tag link is not a natural link so the linkvalue is zero. Anyone any idea how to look at this?

Meta NoIndex tag and Robots Disallow
Hi all, I hope you can spend some time to answer my first of a few questions 🙂 We are running a Magento site - layered/faceted navigation nightmare has created thousands of duplicate URLS! Anyway, during my process to tackle the issue, I disallowed in Robots.txt anything in the querystring that was not a p (allowed this for pagination). After checking some pages in Google, I did a site:www.mydomain.com/specificpage.html and a few duplicates came up along with the original with
Intermediate & Advanced SEO | | bjs2010
"There is no information about this page because it is blocked by robots.txt" So I had added in Meta Noindex, follow on all these duplicates also but I guess it wasnt being read because of Robots.txt. So coming to my question. Did robots.txt block access to these pages? If so, were these already in the index and after disallowing it with robots, Googlebot could not read Meta No index? Does Meta Noindex Follow on pages actually help Googlebot decide to remove these pages from index? I thought Robots would stop and prevent indexation? But I've read this:
"Noindex is a funny thing, it actually doesn’t mean “You can’t index this”, it means “You can’t show this in search results”. Robots.txt disallow means “You can’t index this” but it doesn’t mean “You can’t show it in the search results”. I'm a bit confused about how to use these in both preventing duplicate content in the first place and then helping to address dupe content once it's already in the index. Thanks! B0 -
Any penalty for having rel=canonical tags on every page?
For some reason every webpage of our website (www.nathosp.com) has a rel=canonical tag. I'm not sure why the previous SEO manager did this, but we don't have any duplicate content that would require a canonical tag. Should I remove these tags? And if so, what's the advantage - or disadvantage of leaving them in place? Thank you in advance for your help. -Josh Fulfer
