Adding a Canonical Tag to each page referencing itself?
-
Hey Mozers!
I've noticed that on www.Zappos.com they have a Canonical tag on each page referencing it self. I have heard that this is a popular method but I dont see the point in canon tagging a page to its self.
Any thoughts?
-
Forgive me if this is a silly question, but does this mean you would need to go and identify all the urls with extra parameters, and add canonical tag pointing to the primary url?
Coz if so, that would be an extremly labourious task, no? Some of my duplicate issues, have 50+ urls that are being counted as 'duplicates'.
There must be a better way, hence, I fear this must be a silly question...

The self-referencing canonical tags should only be for your actual preferred URLs. So if www.testwebsite.com/duplicate is a duplicate because of parameters (for example), then no, it should not have the self-referencing canonical tag - it should have a canonical tag pointing to the preferred URL should (www.testwebsite.com/ in this case, which would have the self-ref tag).
Zappos example:
- http://www.zappos.com/beyond-yoga-women-shirts-tops~1 (self-ref canonical tag)
- http://www.zappos.com/beyond-yoga-women-shirts-tops~1#!/beyond-yoga-women-shirts-tops/CKvXARDL1wFSAv0eegLgBIIBAukjwAEB4gIFGAECCg8.zso (canonical tag points to unfiltered page)
If www.testwebsite.com/duplicate is a static page that you want indexed, but that has the same content as www.testwebsite.com/, then the solution is updating/adding content to be unique (then applying the self-ref canonical tags to both URLs which are now unique).
Make sense?

I've not come across any reason ever that would give cause to be concerned about losing Page Authority by having a page canonical to itself.
-
Well it was more so a concern for me applying this method to my own site more so than a concern for Zappos getting flagged lol
Im curious to know would it do anything at all to the page Authority if you have it Canon tagged to itself?
-
No need to be concerned. Aside from all the really well documented best practices on canonicals, in your original question you've spotted at least one big site that does this. They pay the SEO big bucks and rank well.
-
I would assume that by having each page canon tag itself your basically telling google "Hey I am aware that this is a duplicate but treat it as its own page and not as a version of another". My concern is by doing so your losing potential Page Authority
example:
www.testwebsite.com ---Canonionical--- www.testwebsite.com
www.testwebsite.com/duplicate ---Canonical --- www.testwebsite.com/duplicate
-
Yes this is a good idea as it's a catch all for URLs that might include tracking URL parameters, or other parameters that don't affect the page content. When there are no tracking parameters, it's going to be more development and testing work to hide the canonical, when having it there doesn't cause any issues. It's also quite a brutal but effective catch all if your page was accidentally accessible via other URLs - e.g. non-www or https.

Moz.com does this as well and you may also see an "Insight" in your Moz Analytics account recommending site-wide implementation 'to prevent any unforeseen duplicate content issues.' I have started following this practice since it really can't hurt & sometimes dup content pops up in the weirdest, most 'unforeseen' ways.

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😞

Index, follow on a paginated page with a different rel=canonical URL
Hello, I have a question about meta robots ="index, follow" and rel=canonical on category page pagination. Should the sorted page be <meta name="robots" content="index,follow"></meta name="robots" content="index,follow"> since the rel="canonical" is pointing to a separate page that is different from the URL? Any thoughts on this topic would be awesome. Thanks. Main Category Page

Question on Indexing, Hreflang tag, Canonical
Dear All, Have a question. We've a client (pharma), who has a prescription medicine approved only in the US, and has only one global site at .com which is accessed by all their target audience all over the world.
Intermediate & Advanced SEO | | jrohwer
For the rest of the US, we can create a replica of the home page (which actually features that drug), minus the existence of the medicine, and set IP filter so that non-US traffic see the duplicate of the home page. Question is, how best to tackle this semi-duplicate page. Possibly no-index won't do because that will block the site from the non-US geography. Hreflang won't work here possibly, because we are not dealing different languages, we are dealing same language (En) but different Geographies. Canonical might be the best way to go? Wanted to have an insight from the experts. Thanks,

Canonical Tags increased after putting the appropriate tag?
Hey, I noticed that the number of duplicate title tags increased from 14k to 30k in Google Search Console. These dup title tags derived from having the incorrect canonical tags. For instance, http://www.site.com/product-name/product-code/?d=Mens
Intermediate & Advanced SEO | | ggpaul562
http://www.site.com/product-name/product-code/?d=Womens These two are the same exact pages with two parameters (These are not unisex by the way). Anyway, when I viewed the page source, it had the parameter in the canonical tag so.... it would look like this So whether it be http://www.site.com/product-name/product-code/
http://www.site.com/product-name/product-code/?d=Mens
http://www.site.com/product-name/product-code/?d=Womens The canonical tag had the "?d=Womens" I figured that wasn't best practices, so for the canonical tag I removed the parameter so now the canonical tag is http://www.site.com/product-name/product-code/ for that specific page with parameter (if that makes sense). My question is, why did my number of errors doubled after what I thought fixed the solution?0 -
Would it work to place H1 (or important page keywords) at the top of your page in HTML and move lower on page with CSS?
I understand that the H1 tag is no longer heavily correlated with stronger ranking signals but it is more important that Keywords or keyphrases are at the top of a page. My question is, if I just put my important keyword (or H1) toward the top of my page in the HTML and move it towards the middle/lower portion with css position elements, will this still be viewed by Googlebot as important keywords toward the top of my page?

What is the proper way to execute 'page to page redirection'
I need to redirection every page of my website to a new url of another site I've made. I intend to add:"Redirect 301 /oldpage.html http://www.example.com/newpage.html"I will use the 301 per page to redirect every page of my site, but I'm confused that if I add:"Redirect 301 / http://mt-example.com/" it will redirect all of my pages to the homepage and ignore the URLs i have separately mentioned for redirection.Please guide me.

Rel Canonical on Home Page
I have a client who says they can't implement a 301 on their home page. They have tow different urls for their home page that are live and do not redirect. I know that the best solution would be to redirect one to the main URL but they say this isn't possible. So they implemented the rel canonical instead. Is this the second best solution for them if they can't redirect? Will the link juice be passed through the rel canonical? Thanks!

How would you handle 12,000 "tag" pages on Wordpress site?
We have a Wordpress site where /tag/ pages were not set to "noindex" and they are driving 25% of site's traffic (roughly 100,000 visits year to date). We can't simply "noindex" them all now, or we'll lose a massive amount of traffic. We can't possibly write unique descriptions for all of them. We can't just do nothing or a Panda update will come by and ding us for duplicate content one day (surprised it hasn't already). What would you do?
