Rel Alternate tag and canonical tag implementation question
-
Hello, I have a question about the correct way to implement the canoncial and alternate tags for a site supporting multiple languages and markets.
Here's our setup. We have 3 sites, each serving a specific region, and each available in 3 languages.
- www.example.com : serves the US, default language is English
- www.example.ca : serves Canada, default language is English
- www.example.com.mx : serves Mexico, default language is Spanish
In addition, each sites can be viewed in English, French or Spanish, by adding a language specific sub-directory prefix ( /fr , /en, /es).
The implementation of the alternate tag is fairly straightforward.
For the homepage, on www.example.com, it would be:
-MX” href=“http://www.example.com.mx/index.html” /> -MX” href=”http://www.example.com.mx/fr/index.html“ />
-MX” href=”http://www.example.com.mx/en/index.html“ />
-US” href=”http://www.example.com/fr/index.html” />
-US” href=”http://www.example.com/es/index.html“ />
-CA” href=”http://www.example.ca/fr/index.html” />
-CA” href=”http://www.example.ca/index.html” />
-CA” href=”http://www.example.ca/es/index.html” />My question is about the implementation of the canonical tag.
Currently, each domain has its own canonical tag, as follows:
rel="canonical" href="http://www.example.com/index.html"> <link rel="canonical" href="http: www.example.ca="" index.html"=""></link rel="canonical" href="http:>
<link rel="canonical" href="http: www.example.com.mx="" index.html"=""></link rel="canonical" href="http:>I am now wondering is I should set the canonical tag for all my domains to:
<link rel="canonical" href="http: www.example.com="" index.html"=""></link rel="canonical" href="http:>
This is what seems to be suggested on this example from the Google help center.

What do you think?

Thank you for your responses. I did get a weird feeling about canonicalizing my .co.uk and .ca sites into my .com site. I leave the canonical tag on each country specific TLD, referencing the canonical URL of the page within each TLD site.

I agree with Alan on this.
Canonical is meant to link identical pieces of content. If the content is in a different language it's not identical and you would want it to appear in the index separately.

i think that page is misleading, this page is clearer

Dont use a canonical, if the have different tlds, only if they are in the same tld.
This video sums it up, you should at least localize your site,
if you have a US a UK and AU site, all in english, this is ok, but you should have currency and date formats to match.

Why isn't the canonical tag on my client's Magento site working?
The reason for this mights be obvious to the right observer, but somehow I'm not able to spot the reason why. The situation:
Intermediate & Advanced SEO | | Inevo
I'm doing an SEO-audit for a client. When I'm checking if the rel=canonical tag is in place correctly, it seems like it: view-source:http://quickplay.no/fotball-mal.html?limit=15) (line nr 15) Anyone seing something wrong with this canonical? When I perform a site:http://quickplay.no/ search, I find that there's many url's indexed that ought to have been picked up by the canonical-tag: (see picture) ..this for example view-source:http://quickplay.no/fotball-mal.html?limit=15 I really can't see why this page is getting indexed, when the canonical-tag is in place. Anybody who can? Sincerely 🙂 GMdWg0K0 -
Is this all that is needed for a 'canonical' tag?
Hello, I have a Joomla site. I have put in a plugin to make the page source show: eg. <link href="[http://www.ditalia.com.au/designer-fabrics-designer-fabric-italian-material-and-french-lace](view-source:http://www.ditalia.com.au/designer-fabrics-designer-fabric-italian-material-and-french-lace)" rel="<a class="attribute-value">canonical</a>" /> Is this all that is need to tell the search engines to ignore the any other links or indexed pages with a url which is created automatically by the system before the SEF urls are initiated?

Paging Question: Rel Next or Canonical?
Hi, Lets say you have a category which displays a list of 20 products and pagination of up to 10 pages. The root page has some content but when you click through the paging the content is removed leaving only the list of products. Would it be best to apply a canonical tag on the paging back to the root or apply the prev/next tags. I understand prev/next is good for say a 3 part article where each page holds unique content but how do you handle the above situation? Thanks

SEOMOZ Diagram question
Hi, On this SEOMOZ help page (http://www.seomoz.org/learn-seo/internal-link) the diagram explaining the optimal link structure (image also attached) has me a little confused. From the homepage, if the bot crawls down the right-hand link first, will it not just hit a dead end where it cant crawl any further and disappear? OR... will it hit the end of the structure and then crawl backwards to the homepage again and follow down another link and then just repeat the process until all pages are indexed? Cheers pyramid.jpg

Do I need to use canonical tags if I'm 301 redirecting pages?
I just took a job about three months and one of the first things I wanted to do was restructure the site. The current structure is solution based but I am moving it toward a product focus. The problem I'm having is the CMS I'm using isn't the greatest (and yes I've brought this up to my CMS provider). It creates multiple URL's for the same page. For example, these two urls are the same page: (note: these aren't the actual urls, I just made them up for demonstration purposes) http://www.website.com/home/meet-us/team-leaders/boss-man/

http://www.website.com/home/meet-us/team-leaders/boss-man/bossman.cmsx (I know this is terrible, and once our contract is up we'll be looking at a different provider) So clearly I need to set up canonical tags for the last two pages that look like this: With the new site restructure, do I need to put a canonical tag on the second page to tell the search engine that it's the same as the first, since I'll be changing the category it's in? For Example: http://www.website.com/home/meet-us/team-leaders/boss-man/ will become http://www.website.com/home/MEET-OUR-TEAM/team-leaders/boss-man My overall question is, do I need to spend the time to run through our entire site and do canonical tags AND 301 redirects to the new page, or can I just simply redirect both of them to the new page? I hope this makes sense. Your help is greatly appreciated!!0 -
Title Attribute for H2 & h3 Tag SEO Question
Hi , We have an eCommerce Site and from looking at a competitor , they seem to be rank better than us even though our everything about our site is better . We hire the same products (are affiliated the same company) so the product list is the same. Both our category pages score A grade in Seomoz reports. So This is what I can deduce from the competitors category page I am trying to compete against. On the cement Mixer hire category page The competitor has put the Main Keyword "Cement mixer hire" in all the Title Attributes on their H2 and H3 tags as well as it being the main H1 tag. They have 5 product links in h3 tags all with the same title attribute (cement mixer hire) These links go through to product page. Am I missing a trick here ?..... I would have though using the title attribute so much for main keyword would be a bit spammy ?. I have copied them with the point 1 but I have not done mine h3 as yet. Just wondering that the SEO guru's thought ?. thanks Sarah

Multilingual sites: Canonical and Alternate tag implementation question
Hello, I would like some clarification about the correct implementation of the rel="alternate" tag and the canonical tag. The example given at http://support.google.com/webmasters/bin/answer.py?hl=en&answer=189077 recommends implementing the canonical tag on all region specific sub-domains, and have it point to the www version of the website Here's the example given by Google. My question is the following. Would this technique also apply if I have region specific sites site local TLD. In other words, if I have www.example.com, www.example.co.uk, www.example.ca – all with the same content in English, but prices and delivery options tailored for US, UK and Canada residents, should I go ahead and implement the canonical tag and alternate tag as follows: I am a bit concerned about canonicalizing an entire local TLD to the .com site.

Use of the Canonical Tag, Both Internally and Cross Domain
I've seen the cross domain canonical not work at all in my test cases. And an interesting point was brought to my attention today. That point was that in order for the canonical tag to work, the page that you are referencing needs to have the exact same content. And that this was the whole point of the canonical tag, not for it to be used as a 301 but for it to consolidate pages with the same content. I want to know if this is true. Does the page you reference with a canonical tag have to have the same exact content? And what have been your experiences with using the canonical tag referencing another page on a different domain that has the same exact subject matter but not the exact duplicate content?
