Rel=canonical tag on original page?
-
Afternoon All,
We are using Concrete5 as our CMS system, we are due to change but for the moment we have to play with what we have got. Part of the C5 system allows us to attribute our main page into other categories, via a page alaiser add-on. But what it also does is create several url paths and duplicate pages depending on how many times we take the original page and reference it in other categories. We have tried C5 canonical/SEO add-on's but they all seem to fall short.We have tried to address this issue in the most efficient way possible by using the rel=canonical tag. The only issue is the limitations of our cms system. We add the canonical tag to the original page header and this will automatically place this tag on all the duplicate pages and in turn fix the problem of duplicate content. The only problem is the canonical tag is on the original page as well, but it is referencing itself, effectively creating a tagging circle. Does anyone foresee a problem with the canonical tag being on the original page but in turn referencing itself?
What we have done is try to simplify our duplicate content issues. We have over 2500 duplicate page issues because of this aliasing add-on and want to automate the canonical tag addition, rather than go to each individual page and manually add this tag, so the original reference page can remain the original.
We have implemented this tag on one page at the moment with 9 duplicate pages/url's and are monitoring, but was curious if people had experienced this before or had any thoughts?

My experience matches Nakul's. Technically, Bing claims you shouldn't have canonicals on the canonical page itself, but I've never seen evidence that they actually do anything about that or don't honor the tags. I think they just don't like processing the extra tags. Google originally suggested the same thing, but then softened their stance. I've NEVER seen a practical issue with it on Google.
So, by the book, Bing would rather you only put it on non-canonical URLs. Practically, though, it seems to work absolutely fine. I wouldn't lose sleep over it. So many big sites are doing this now that I don't think the engines can devalue the tactic. It's not spammy - it's just mildly inconvenient for them (some extra processing).

I implemented the canonical tag last year in a similar situation and yes, it's on the original page as well. No issues. Look at eBay.com, they also have canonical tags on all pages including the original page.
I have not seen/encountered any issues. Now when I go check the cache for http://www.example.com/duplicate-url-3.html which has a canonical tag referring to the original-url, Google shows me the canonical URL. The duplicate pages literally disappear from the SERPS, because essentially its like a 301 redirect.

Should I apply Canonical Links from my Landing Pages to Core Website Pages?
I am working on an SEO project for the website: https://wave.com.au/ There are some core website pages, which we want to target for organic traffic, like this one: https://wave.com.au/doctors/medical-specialties/anaesthetist-jobs/ Then we have basically have another version that is set up as a landing page and used for CPC campaigns. https://wave.com.au/anaesthetists/ Essentially, my question is should I apply canonical links from the landing page versions to the core website pages (especially if I know they are only utilising them for CPC campaigns) so as to push link equity/juice across? Here is the GA data from January 1 - April 30, 2019 (Behavior > Site Content > All Pages😞

Best Practices for Title Tags for Product Listing Page
My industry is commercial real estate in New York City. Our site has 300 real estate listings. The format we have been using for Title Tags are below. This probably disastrous from an SEO perspective. Using number is a total waste space. A few questions:
Intermediate & Advanced SEO | | Kingalan1
-Should we set listing not no index if they are not content rich?
-If we do choose to index them, should we avoid titles listing Square Footage and dollar amounts?
-Since local SEO is critical, should the titles always list New York, NY or Manhattan, NY?
-I have red that titles should contain some form of branding. But our company name is Metro Manhattan Office Space. That would take up way too much space. Even "Metro Manhattan" is long. DO we need to use the title tag for branding or can we just focus on a brief description of page content incorporating one important phrase? Our site is: w w w . m e t r o - m a n h a t t a n . c o m <colgroup><col width="405"></colgroup>
| Turnkey Flatiron Tech Space | 2,850 SF $10,687/month | <colgroup><col width="405"></colgroup>
| Gallery, Office Rental | Midtown, W. 57 St | 4441SF $24055/month | <colgroup><col width="405"></colgroup>

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?

Why does Google rank a product page rather than a category page?
Hi, everybody In the Moz ranking tool for one of our client's (the client sells sport equipment) account, there is a trend where more and more of their landing pages are product pages instead of category pages. The optimal landing page for the term "sleeping bag" is of course the sleeping bag category page, but Google is sending them to a product page for a specific sleeping bag.. What could be the critical factors that makes the product page more relevant than the category page as the landing page?

Date of page first indexed or age of a page?
Hi does anyone know any ways, tools to find when a page was first indexed/cached by Google? I remember a while back, around 2009 i had a firefox plugin which could check this, and gave you a exact date. Maybe this has changed since. I don't remember the plugin. Or any recommendations on finding the age of a page (not domain) for a website? This is for competitor research not my own website. Cheers, Paul

Wildcard Redirects & Canonical Tags
I have an interesting situation. Current URLs Example1: www.domain.com/red-widgets-cid-1234.html
Intermediate & Advanced SEO | | NakulGoyal
www.domain.com/red-widgets-cid-1234-1.html
www.domain.com/red-widgets-cid-1234-1-1.html Canonical on All Above URLs:

www.domain.com/american-red-widgets-cid-6789+5.html I want to make sure all variations of the above URL redirect to the new URLs. However, as you see in Example 3, we are dealing with variables that are passed on. (+5 in this case). Question 1: What wildcard 301 redirect / regular expression can I use to tackle these ? Question 2: If we redirect www.domain.com/red-widgets-cid-1234+10+5.html to www.domain.com/red-widgets-cid-6789+5.html and www.domain.com/red-widgets-cid-6789+5.html contains the canonical tag www.domain.com/american-red-widgets-cid-6789+5.html, any concerns or red flags here ?0 -
Dynamic pages - ecommerce product pages
Hi guys, Before I dive into my question, let me give you some background.. I manage an ecommerce site and we're got thousands of product pages. The pages contain dynamic blocks and information in these blocks are fed by another system. So in a nutshell, our product team enters the data in a software and boom, the information is generated in these page blocks. But that's not all, these pages then redirect to a duplicate version with a custom URL. This is cached and this is what the end user sees. This was done to speed up load, rather than the system generate a dynamic page on the fly, the cache page is loaded and the user sees it super fast. Another benefit happened as well, after going live with the cached pages, they started getting indexed and ranking in Google. The problem is that, the redirect to the duplicate cached page isn't a permanent one, it's a meta refresh, a 302 that happens in a second. So yeah, I've got 302s kicking about. The development team can set up 301 but then there won't be any caching, pages will just load dynamically. Google records pages that are cached but does it cache a dynamic page though? Without a cached page, I'm wondering if I would drop in traffic. The view source might just show a list of dynamic blocks, no content! How would you tackle this? I've already setup canonical tags on the cached pages but removing cache.. Thanks
