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.

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>

Should I use **tags or h1/h2 tags for article titles on my homepage**
I recently had an seo consultant recommend using tags instead of h1/h2 tags for article titles on the homepage of my news website and category landing pages. I've only seen this done a handful of times on news/editorial websites. For example: http://www.muscleandfitness.com/ Can anyone weigh in on this?

Adding hreflang tags - better on each page, or the site map?
Hello, I am wondering if there seems to be a preference for adding hreflang tags (from this article). My client just changed their site from gTLDs to ccTLDs, and a few sites have taken a pretty big traffic hit. One issue is definitely the amount of redirects to the page, but I am also going to work with the developer to add hreflang tags. My question is - is it better to add them to the header of each page, or the site map, or both, or something else? Any other thoughts are appreciated. Our Australia site, which was at least findable using Australia Google before this relaunch, is not showing up, even when you search the company name directly. Thanks!Lauryn

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

Are pages with a canonical tag indexed?
Hello here, here are my questions for you related to the canonical tag: 1. If I put online a new webpage with a canonical tag pointing to a different page, will this new page be indexed by Google and will I be able to find it in the index? 2. If instead I apply the canonical tag to a page already in the index, will this page be removed from the index? Thank you in advance for any insights! Fabrizio

Accidently added a nofollow, noindex tag and then...
Hey guys, My first post here and ironically highlights a ridiculously stupid mistake! Ok, here's the deal... I started building links to one of my new page on a fairly good, old site (DA = >35). Before starting to build links, I added fresh new content, and while doing that, I accidentally added a "nofollow" and "noindex" tag to the page! Guess what, google DID de-index the page ! So the questions is (and YES, I did change the meta tags): Will google re-index the page with some good linking? Will it treat the page as a new, fresh page even though it was present for over a year? I had already started link building to that page, and now technically the links are pointing to a page that does not exist in the index, so once it does get re-indexed, will Google FLAG it as having too many links? Would I be ranking it as a new page? Will its previous ranking (for very few keywords) will come back? Thanks and Regards, Amod

Rel=canonical tag on original page?
Afternoon All,
Intermediate & Advanced SEO | | Jellyfish-Agency
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?0 -
Should I Allow Blog Tag Pages to be Indexed?
I have a wordpress blog with settings currently set so that Google does not index tag pages. Is this a best practice that avoids duplicate content or am I hurting the site by taking eligible pages out of the index?
