Will this internal linking feature cause canonicalization issues?
-
This is a canonicalization type question, so I believe it should be a pretty straightforward answer. I just haven't had much experience with using the canonical tag so I felt I should ask so I don't blow up my site
Ok, let's say I have a product page that is at:
- www.exampledomain.com/products/nameofproduct
Now on that page I have an option to see all of the specs of the product in a collapsible tab which I want to link to from other pages - So the URL to this tab ends from other pages ends up being:
- www.exampledomain.com/products/nameofproduct?=productspecs
This will link to the tab and default it to open when someone clicks that link on another page.
Correct me if I'm wrong, but if I understand canonicalization correctly I believe creating this link is going to cause a duplicate page that has the opportunity to be indexed and detract from our SEO to the main product page.
My question is... where do I put the "rel=canonical" tag to point the SEO value back to the main page since the page is dynamically generated and doesn't have its own file on the server? - or do even need to be concerned with this?
Feel free to correct me if I'm wrong on any of the above. Like I said - this is something I am fairly familiar with how it works, but I haven't had much experience with using.
Thanks!

We'll be using IIS, but I suppose it works the same way. It's my hope to get this done with one small change and not have to update an entire database of thousands of pages.
Can that not be done?

Hey
So, your product pages are as follows:
productpage.php?productid=1
productpage.php?productid=2
productpage.php?productid=3And you are worried about duplicates that would be in the following format with three versions of product=1
productpage.php?productid=1
productpage.php?productid=1&variation=A
productpage.php?productid=1&variation=B
productpage.php?productid=1&variation=CIf so, then your canonical link for productid=1 which would go on all of the above variations of the productid=1 page would be:
<link <span>rel="canonical" href="productpage.php?productid=1" /></link <span>
Summary
The page name includes the bit that makes it a unique page but you are applying the canonical to all variations of that.
Hope it helps!

Makes sense.
Let me make sure I understand.
So, basically on that parameter page in the I need to have my programmers code the rel=canonical to pass in the URL of the page in the form of "www.exampledomain.com/productpage" - and that will take care of pointing all of the duplicate content generated by those query strings back to each individual product page, and will also ensure each product page is still indexed with its full SEO value?
-
It is one tag, but not one instance of the tag. The canonical must be on each param page referring back to the product page. It would he part of your head that you dynamically generate.
-
Yes this is what I want to do. I want Google to ignore the duplicate pages that would be created by the additional parameters and pass SEO value back to the product page.
What I'm confused about is how to code the tag and how to implement it. Each page, which there are thousands of, is generated dynamically - so I only have that one container page that I can update.
How do I take care of all of the product pages with one tag? Is this something that is done in the database?
Unfortunately we don't have a CMS in place, however it's something we're highly considering.

Is the URL ending in /productname the individual product page? If so, what we are saying will work to canonicalize your product page. You're simply telling Google not to pass pagerank to the /productname?=productspecs page. You're telling them to ignore the specs part of the page as a separate page and to instead pass the link juice to the main page.
Once again, please correct any misunderstandings we may have of what you are trying to do.
Also, you incorporate the canonical tag on a page level. Hopefully you can set this through the CMS (I use Yoast SEO to do this with Wordpress).
-
True, if you want pages to build PR, it needs to to be canonicalized. What you are doing with the canonical is handling anything after the ? and pointing all page value back behind the ? If I'm reading this correctly, why would you want the spec page to gain value? Sorry if I'm not, I'm remote.

Hey guys. Thanks for all of the responses. The query string actually comes from part of a search tool, so I don't know if it can be output as a named anchor. If so it would require reprogramming the search tool. It's possible, but I believe at this point it would probably be easier to use the rel=canonical tag.
What I'm not getting is this:
All of our product pages are dynamically generated. So they are loaded into a page at:
www.exampledomain.com/products/productname
If I put the rel=canonical tag on that host page that is populated with data wouldn't I be throwing out any possibility for my individual product pages to rank? Wouldn't it all point back to that one product?
How do I use the rel=canonical tag so that each individual product page gets all of the ranking. Is there a way to do this?

I was going to suggest this as well, but did not know if it would be relevant. Good suggestion.
Question though. Will he need to specify somewhere on the page to link to the named anchor (i.e. an index on the actual page?) for the named anchors to work, or is this not an issue? This is why I did not suggest it, because I did not know the answer to my question.
-
Named anchors I great if it meets your needs otherwise rel canonical will work.
-
I agree that this is an excellent use of the canonical tag. The canonical tag goes on the host page nameofproduct and then when any other page is called nameofproduct?=productspecs, SEs will give credit to the nameofproduct page**. **
**I hope that answers your question. **

Hey, using the rel=canonical tag on the page will prevent this from being a problem but a better way would be to use named anchors instead of query string variables. Named anchors are page level navigation so you are not creating a potential duplicate version of the same page.
If you use querystring variables, you are creating a problem, and then fixing it with rel=canonical. If you use named anchors as page level navigation, you are never creating the problem in the first place.
- www.exampledomain.com/products/nameofproduct#productspecs
Hope it helps!

Nope that is what i was going to say, but you beat me to it.
-
I know that you put the canonical tag in the of your page, so it looks like:
rel="canonical" href="(originalpageURL)" />
Since you are linking a dynamic part of that page, the rel=canonical that you have specified there will hold for the page. It will be a dynamic page, but it is a subset of the page, so you should be fine.
Someone PLEASE correct me if I am wrong.

Links from a penalised site.
Hey Mozzers, Recently we have had a series of agencies in to pitch for work, one group mentioned that due to our association with a possibly penalised product review website, any links and activity associated with the brand would hinder our SEO. We currently have a good rating, but we are now no longer pushing our customers to the site as we move to a new platform. The current link back from this website is also no-followed. Any thoughts on how this could impact us? And how the agencies determined the site was penalised and causing us problems. Cheers Tim

Huge problem : All our Internal Links Dropped from 9.000 to 0.What happened?
Hi, I just noticed a huge large problem in our rankings. Our rankings suddenly dropped for more than 50 %. Of course, I immediately started to research the issue. And under Links, I found that we somehow lost all of our internal links! They have dropped from 9k to 0. Now, I am sure that we do have some internal links on our site ( since I put them there myself). Could you please tell me what is going on and how I can fix this issue? Our site is 1solarsolution.com and I will also attach screenshots bellow from Link Explorer, thank you. Fr08UGe

Potential Pagination Issue/ Duplicate content issue
Hi All, We upgraded our framework , relaunched our site with new url structures etc and re did our site map to Google last week. However, it's now come to light that the rel=next, rel=Prev tags we had in place on many of our pages are missing. We are putting them back in now but my worry is , as they were previously missing when we submitted the , will I have duplicate content issues or will it resolve itself , as Google re-crawls the site over time ?.. Any advice would be greatly appreciated? thanks Pete

Problem with internal links
Hello! Our domain, http://www.unionroom.com/, is having a strange issue with OSE in that it is telling us our internal pages aren't linking to one another. An example of this is that it is showing our About page ( http://www.unionroom.com/about/ ) only having three links, but this link appears twice on every single page on the website (~200 pages) in the header and footer. We've hung around for a little while to see if OSE would correct itself, but it hasn't and this now suggests that it may be an issue with our in-linking structure. Can anyone spot any issues with our build? The rest of the websites that we produce, that are all built in the same way, all have healthy internal linking structures according to OSE. Very confusing! Any help would be greatly appreciated.

Canonicalized Website
We are new to SEO MOZ, and as we are doing our evaluation, multiple page problems have arisen. Our domain is www.moxicopy.com and www.moxicopy.com/blog. Our blog is wordpress hosted but integrated into our site. As we ran our analytics from MOZ PRO, we got TONS of Duplicate Page Title and Duplicate Page Content warnings, over 90 each. Most seem to come from our blog and our different products (we are an ecommerce website). Would the canonicalization of the pages be the cause? And couuld someone further explain exactly what canonical/canonicalization is>? I am very confused, and have a feeling that this is what has hurt our site so much in the last 2-3 weeks
