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.

Null Alt Image Tags vs Missing Alt Image Tags
Hi, Would it be better for organic search to have a null alt image tag programatically added to thousands of images without alt image tags or just leave them as is. The option of adding tailored alt image tags to thousands of images is not possible. Is having sitewide alt image tags really important to organic search overall or what? Right now, probably 10% of the sites images have alt img tags. A huge number of those images are pages that aren Thanks!

Is a 301 Redirect and a Canonical Tag on Uppercase to Lowercase Pages Correct?
We have a medium size site that lost more than 50% of its traffic in July 2013 just before the Panda rollout. After working with a SEO agency, we were advised to clean up various items, one of them being that the 10k+ urls were all mixed case (i.e. www.example.com/Blue-Widget). A 301 redirect was set up thereafter forcing all these urls to go to a lowercase version (i.e. www.example.com/blue-widget). In addition, there was a canonical tag placed on all of these pages in case any parameters or other characters were incorporated into a url. I thought this was a good set up, but when running a SEO audit through a third party tool, it shows me the massive amount of 301 redirects. And, now I wonder if there should only be a canonical without the redirect or if its okay to have tens of thousands 301 redirects on the site. We have not recovered yet from the traffic loss yet and we are wondering if its really more of a technical problem than a Google penalty. Guidance and advise from those experienced in the industry is appreciated.

Block in robots.txt instead of using canonical?
When I use a canonical tag for pages that are variations of the same page, it basically means that I don't want Google to index this page. But at the same time, spiders will go ahead and crawl the page. Isn't this a waste of my crawl budget? Wouldn't it be better to just disallow the page in robots.txt and let Google focus on crawling the pages that I do want indexed? In other words, why should I ever use rel=canonical as opposed to simply disallowing in robots.txt?

Canonical tag + HREFLANG vs NOINDEX: Redundant?
Hi, We launched our new site back in Sept 2013 and to control indexation and traffic, etc we only allowed the search engines to index single dimension pages such as just category, brand or collection but never both like category + brand, brand + collection or collection + catergory We are now opening indexing to double faceted page like category + brand and the new tag structure would be: For any other facet we're including a "noindex, follow" meta tag. 1. My question is if we're including a "noindex, follow" tag to select pages do we need to include a canonical or hreflang tag afterall? Should we include it either way for when we want to remove the "noindex"? 2. Is the x-default redundant? Thanks for any input. Cheers WMCA

Does City In Title Tag Inhibit Broader Reach?
I use our city/state in the majority of our title tags and consequently we do very well locallly for the majority of terms on our ecommerce site. I'm wondering however, if this "localized" optimization will inadvertently affect our keyword rankings outside of our city/state? If a keyword query does not include our city or state, would Google interpret our titles as less relevent and therefore move other results ahead of ours? The city/state is last in the string on the title: Blue Widgets - Our Company in City, State Thanks for any insight.

Why should your title and H1 tag be different?
Is it dangerous to have your H1 tag and your title the exact same thing? My thought was that it's not be the best use of space, but that it couldn't cause harm. What do you think?
