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!

Yes, I will look into doing that on GWT.
Was a nice and useful chat indeed! Thank you again.

Sorry Fabrizio I got mad with my old answer
that canonical doesn't make sense with a noindex, with noindex follow.you're completely fine.
Summing up I think that you have many parameters so you should try to write them down and define the role of each one.
Then add them in GWT and choose there which are the ones which doesn't add any value and which you want to "block" (instead of putting a noindex).
The valuable ones (the one which adds value and changes content) should contain the self canonical and paginated next/prev. If you can get rid of unesful parameters it could be better so to have cleaner and shorter urls.
Just be sure that you're mainly using the most important parameters so you're consistent with your strategy.
Hope this will clear your doubts, it was a nice chat!

Yes, actually I could get rid of the lpg parameter (it wasn't really needed!), so now the tag definitions are (for the 3rd page of the Guitar index):
<LINK rel="<a class="attribute-value">next</a>" href="[http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=4](view-source:http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=4)"> <LINK rel="<a class="attribute-value">prev</a>" href="[http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=2](view-source:http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=2)"> <LINK rel="<a class="attribute-value">canonical</a>" href="[http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=3](view-source:http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=3)">
Now, the only doubt I still have is to add or not add the noindex tag to the page when it is requested to be displayed in a different way (such as the "table view" or a different item display order). In my opinion, if I stick with the canonical tag I don't need a noindex directive. What do you think?
-
Yeah, to be fair, I'm not clear on what all of the additional parameters (like "lpg=") do, so this can get tricky fast. Basically, look at it this way:
If the URL is:
example.com/page=3?param=xThen the tags should point to:
Rel=prev:
example.com/page=2?param=xRel=next:
example.com/page=4?param=xRel=canonical:
example.com/page=3 (no parameters)Some parameters may not be indexed and/or functional, though, so individual cases can vary. You may choose to ignore some parameters in Google Webmaster Tools, for example. It gets tricky as the parameter list grows.
-
Mememax, after thinking I have some doubts though about what you have suggested.
Why I want to put a noindex tag to the page displaying the list in "table view" if I already have a canonical tag pointing to the "regular view" page? Wouldn't the canonical tag be enough for the purpose of telling that the "real" canonical page is the "regular view" version? I am asking this because if I want to apply a noindex tag to that kind of different view, I may want to do the same to the list displayed with a different order, and for any other different way of displaying the list, etc... hence just using the canonical tag would be appropriate, pointing always to the "regular list" view, no matter what kind of "filtering" or "different view' option is selected. What do you think?
In other words, I don't think I need to include a noindex tag for any different kind of view the user requests as long as I provide a canonical tag pointing to the regular view list.
Am I correct?
-
Yes, thank you Mememax, I agree with you 100%. That makes perfect sense and I will work on that tomorrow morning. I am eager to know Dr. Peter thoughts and confirmation.
On my side, I think I got it cleared-up now. Thank you very much again!
-
Thank you ! That makes sense now.

Hey Fabrizio, I think that what Google states in their guidelines is that you have two choices:
- if you have a view all page, you should noindex and follow all your other pages so google will deliver only that page
- if you don't have a view all page or if you prefer to show paginated series (i.e. to make pages lighter and quicker to deliver to users) you may consider to use rel next/prev.
In this second case it may happen that you also add filters or session ids in the urls of those pages, in that case you should consider adding a self referentail canonical tag to avoid duplicates. But this is only if you cover this case, if you're looking to canonicalize correctly your paginated series you may not use the self canonical tag, because if not properly implemented this may get you a bit of extra work.
In this page for example
I found this:
http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=3&lpg=0">
Which I don't think is what you want to do.
Also if you set the page to view as a table: your url changes to http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=3&viewlistflag=1
and while the canonical should remain the same (well done but I think you should get rid of the lpg parameter in the canonical), the rel next prev should change accordingly IMO.
So instead of being:
prev: http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=2&lpg=20
next: http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=4&lpg=60you should offer the next and prev page of the filtered url:
next: http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=4&lpg=60&viewlistflag=1
prev: http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=2&lpg=20&viewlistflag=1Or in this case (since the content is almost the same you may consider the list page as the canonical of the table one putting there a noindex.
Summing up, IMO: in this page http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=3
you'll have:
prev: http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=4&lpg=60
next: http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=2&lpg=20
(optional) a self canonical to http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=3In this page (and in other filtered pages if you have apply the same idea):
http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=3&viewlistflag=1You'll have:
noindex,follow and canonical to the list page:
http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=3maybe dr peter can correct me if I'm wrong but I think this should be more consistent like this. Sorry for the huge answer
-
Wow, yes - sorry about that. I've updated it. Google original write-up actually covers this case, too (it's toward the end):
http://googlewebmastercentral.blogspot.com/2011/09/pagination-with-relnext-and-relprev.html
-
Please, have a look at the page below, I have modified the canonical tag as suggested:
http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=3&lpg=40
Is that correct?
Thank you again very much.
-
Thank you Peter, I guess you meant to have the "canonical" tag as last tag in your example above, and also the previous rel=next and rel=prev definitions should be inverted:
Am I correct? That makes sense. If so, I will update my site to reflect this.
Thank you for the link!
-
This gets tricky fast. Google currently wants rel=prev/next to contain the parameters currently in use (like sorts) for the page you're on and then wants you rel-canonical to the non-parameterized version. So, if the URL is:
http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=3&lpg=40
...then the tags should be...
Yeah, it's a bit strange. They have suggested that it's ok to rel-canonical to a "View All" page, but with the kind of product volume you have, that's generally a bad idea (for users and search). The have specifically recommended against setting rel-canonical to Page 1 of search results, especially if you use rel=prev/next.
Rel=prev/next will still show pages in the index, but I've found it to work pretty well. The other option is the more classic approach to simple META NOINDEX, FOLLOW pages 2+. That can still be effective, but it's getting less common.
Adam Audette has generally strong posts about this topic - here's a good, recent one:

Thank you for your post, and I think you have just opened a doubt I had, and that's exactly what also concerned me.
Have a look at this typical category page of ours:
http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html
For that category pagination, I have implemented the rel=prev/next as suggested by Google, but being afraid to be penalized for duplicate content, I also put a canonical tag pointing at the first page of that index. Should I have put the canonical tag pointing to the page series itself?
Something like:
http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html?cp=2
for the second page instead of the general:
http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html
as I am currently doing?
Thanks!

I have to disagree on this one. If Google honors a canonical tag, the non-canonical page will generally disappear from the index, at least inasmuch as we can measure it (with "site:", getting it to rank, etc.). It's a strong signal in many cases.
This is part of the reason Google introduced rel=prev/next for paginated content. With canonical, pages in the series aren't usually able to rank. Rel=prev/next allows them to rank without clogging up the index (theoretically). For search pagination, it's generally a better solution.
If your paginated content is still showing in large quantities in the index, Google may not be honoring the canonical tag properly, and they could be causing duplicate content issues. It depends on the implementation, but they recommend these days that you don't canonical to the first page of search results. Google may choose to ignore the tag in some cases.
-
Thank you very much, that makes perfect sense. In my case, I am talking exactly about paginated content, and that's probably why all pages are in the index despite they are canonicalized to point to the main page. So, I guess that even if you have thousands of paginated pages indexed (mine is a pretty big e-commerce website), that's not going to be an issue. Am I right?
-
Normally the only thing which will prevent a page from ranking is noindex tag. If you don't want to have it indexed just noindex it, if that page has been laready indexed, put the noindex tag and delete from index using GWT option.
Concerning the canonical tag thing, it will consolidate the seo value in one page but it won't prevent those page to appear in rankings, however you may have two cases:
- the two or more pages are identical. In that case google may accept the canonicalization and show always the original page.
- the two or more pages are slightly different, it's the case of paginated pages which are canonicalized using rel next/prev. In that sense the whole value will be consolidated in page 1 but then the page which will be shown in the rankings will be the one which responds to that query, for example if someone is looking for blue glass, google will return the page which shows blue glass listing if that's different from the first one.
Hope this may help you!

Original Source Tag or Canonical Tag for News Publishers?
I have been sourcing content from a news publisher who is my partner for publishing content online. My website deals with sourcing content from a couple of websites. I did use a canonical tag pointing towards the respective syndicated source but I have not seen traffic for those articles. I did some research and found out that Google does have a tag for news publishers which is the "original-source" tag which helps news publishers to give proper credit for their work. Here's a link to the official word by Google" https://news.googleblog.com/2010/11/credit-where-credit-is-due.html Although Google has officially stated that the "syndication-source" tag has been replaced by the "canonical" tag. However, there is no mention about the "original-source" tag.

Can I still use the "original-source" tag to syndicate content from my partner site instead of the "canonical" tag? P.S.: The reason why I am not convinced with the use of the canonical tag is because:
1. As per what Google says, duplicate content won't harm my website unless it is spam. (And since we are rightfully content from our partner'website and showcasing it to a larger audience by hosting it on our website as well, we are thereby not indulging in any unethical practices) 2. The canonical tag could possibly hamper my crawl bandwidth issues as it would essentially need the crawler to crawl the whole page to figure out that the canonical is present, post which any possible valuation that my site could have garnered gets lost.3. Moreover, since I am from the news, media and publication industry, content republication is a widely accepted practice and in such cases simply including a link to the original source of the article or using the original source tag should suffice, That being mentioned, I do not want to go ahead without taking a second opinion about this. Kindly help me to resolve this issue.0 -
Changing Canonical Tags on Indexed Pages that are Ranking Well
Hi Guys, I recently rolled out a domain wide canonical tag change. Previously the website had canonical tags without the www, however the website was setup to redirect to www on page load. I noticed that the site competitors were all using www and as far as I understand www versus non www, it's based on preference. In order to keep things consistent, I changed the canonical tag to include the www. Will the site drop in rankings? Especially if the pages are starting to rank quite well. Any feedback is appreciated. Thanks!

Google indexing only 1 page out of 2 similar pages made for different cities
We have created two category pages, in which we are showing products which could be delivered in separate cities. Both pages are related to cake delivery in that city. But out of these two category pages only 1 got indexed in google and other has not. Its been around 1 month but still only Bangalore category page got indexed. We have submitted sitemap and google is not giving any crawl error. We have also submitted for indexing from "Fetch as google" option in webmasters. www.winni.in/c/4/cakes (Indexed - Bangalore page - http://www.winni.in/sitemap/sitemap_blr_cakes.xml) 2. http://www.winni.in/hyderabad/cakes/c/4 (Not indexed - Hyderabad page - http://www.winni.in/sitemap/sitemap_hyd_cakes.xml) I tried searching for "hyderabad site:www.winni.in" in google but there also http://www.winni.in/hyderabad/cakes/c/4 this link is not coming, instead of this only www.winni.in/c/4/cakes is coming. Can anyone please let me know what could be the possible issue with this?

According to https://developers.google.com/webmasters/smartphone-sites/details, we should include a canonicalicalize back to our desktop version of the URL, but what if that desktop URL is noindexed? Should the m. version be noindexed as well? Or is it fine to leave it as a canonical?

De Index Section of Page?
Hey all! We're having a couple of issues with a certain section of our page that we don't want to index. Basically, our cross sells change really quickly, and big G is ranking them and linking to them even when they've long gone. Is it possible to put some kind of no index tag for a specific section of the page? See below 🙂 http://www.freestylextreme.com/uk/Home/Brands/DC-Shoe-Co-/Mens-DC-Shoe-Co-Hoodies-and-Sweaters/DC-Black-Rob-Dyrdek-Official-Sweater.aspx Thanks!

Canonical Tags & Search Bots
Does anyone know for sure if search engine bots still crawl links on a page whose canonical tags are set to a different page? So in short, would it be similar to a no-index follow? Thanks! -Margarita

Use of rel=canonical to view all page & No follow links
Hey, I have a couple of questions regarding e-commerce category pages and filtering options: I would like to implement the rel=canonical to the view all page as suggested on this article on googlewebmastercentral. If you go on one of my category pages you will see that both the "next page link" and the "view all" links are nofollowed. Is that a mistake? How does nofoolow combines with canonical view all? Is it a good thing to nofollow the "sorty by" pages or should I also use Noindex for them?

Landing page indexed and ranking in less then 24 hours
Hi, I got a landing page which went up last night about 11pm. Its been indexed and ranked since then. Its a EMD and has about 600 words of unqiue content. It currently sits on page 9 for what I would say is a non competitive term (the top result is not an EMD and has 10 backlinks from the same site, which has no PR). Now my question is this: Would you say that page 9 is the given position Google thinks this website should sit at? Or because its so new could I very much expect some more movement? Basically up the rankings? Cheers
