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.

Ranking dropped after changing title tag
I recently changed my company's site homepage title tag to make it start with our target keyword. The page was originally at page #7 or #8 and dropped to page #17 directly after I changed the page title. Is this normal? Is it's a temporary drop or should I change it back to the previous title.

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.

Should I add no-follow tags to my widget links?
Matt Cutts recommended in a video in 2013 to add rel="nofollow" on widget links that link back to your website. Some background of my company: We're a software company for website chat. There's a 'powered by' link in our widgets that links back from our users' websites to our website. Currently these are all follow links. I checked out the links of our competitors, and it seems none of them have no follow on their widget backlinks. This, together with the fact that the video is quite old and information on this issue rather scarce, makes me doubt whether we should change our widget backlinks to no follow. Does anyone have thoughts on this?

Pagination parameters and canonical
Hello, We have a site that manages pagination through parameters in urls, this way: friendly-url.html
Intermediate & Advanced SEO | | teconsite
friendly-url.html?p=2
friendly-url.html?p=3
... We've rencently added the canonical tag pointing to friendly-url.html for all paginated results. In search console, we have the "p" parameter identified by google.
Now that the canonical has been added, should we still configure the parameter in search console, and tell google that it is being use for pagination? Thank you!0 -
Canonical tag - but Title and Description are slightly different
I am building a new SEO site with a "Silo" / Themed architecture. I have a travel website selling hotel reservations. I list a hotel page under a city page - example, www.abc.com/Dallas/Hilton.html Then I use that same property under a segment within the city - example www.abc.com/Dallas/Downtown/Hilton.html, so there are two URLs with the same content Both pages are identical, except I want to customize the Title and Description. I want to customize the title and description to build a consistent theme - for example the /Downtown/Hilton page will have the words "Near Downtown" in the Title and Description, while the primary city Hilton page will not. So I have two questions about this. First, is it okay to use a canonical tag if the Title and Description are slightly different? Everything else is identical. If so, will Google crawl and comprehend the unique Title and Description on the "Downtown" silo? I want Google to see that I have several "supporting" pages to my main landing page(s). I want to present to Google 5 supporting pages in each silo that each has a supporting keyword theme. But I'm not sure if Google will consider content of pages that point to a different page using the canonical tag. Please see this supporting example: http://d.pr/i/aQPv Thanks for your insights. Rob

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
