Duplicate Content, Campaign Explorer & Rel Canonical
-
Google Advises to use Rel Canonical URL's to advise them which page with similiar information is more relevant.
You are supposed to put a rel canonical on the non-preferred pages to point back to the desired page.
How do you handle this with a product catalog using ajax, where the additional pages do not exist? An example would be:
<colgroup><col width="470"></colgroup>
|.com/productcategory.aspx?page=1
/productcategory.aspx?page=2
/productcategory.aspx?page=3
/productcategory.aspx?page=4
The page=1,2,3 and 4 do not physically exist, they are simply referencing additional products
I have rel canonical urls' on the main page www.examplesite.com/productcategory.aspx, but I am not 100% sure this is correct or how else it could be handled.
Any Ideas Pro mozzers?

Hoping for the extra points here, so here goes how we handled the problem.
The solution is a lot simpler than all the thought needed, or used by us to rationalize the answer, and it has been working beautifully. Our Google webmaster tools show constant improvement weekly without us doing any additional work.
We Canonicalized the first paginated results. ".com/productcategory.aspx" not ".com/productcategory.aspx?page=1" so now all pages link their juice back to the main page ".com/productcategory.aspx". GWT doesn't even care about setting the parameter "Page=" And we didn't include the Canonical tag for the product pages, because each product has its own link juice that we want to preserve, so that each product may "Star" as its own as a google result.
So all we did was to include a single canonical tag for the paginated category page and wala the hole solution works in GWT.

Hi Christian,
It's likely a setting in the Platinum SEO plugin related to canonical URLs. The notice from SEOmoz is just a notice letting you know they are there, and not an error.
If you have specific questions (like if your plugin and template is set up correctly), I suggest starting a new question thread and including your site's URL.

Hi! I have no idea what any of this means. I have "14 rel canonical urls" and I have never entered a "rel canonical url" on on any of my templates (are you talking about the css?)
I use "platinum seo" plugin and the sites that have the most of these errors seem to be the ones I'm using the "Socrates" template.
Help!

Hi! We're going through some of the older unanswered questions and seeing if people still have questions or if they've gone ahead and implemented something and have any lessons to share with us. Can you give an update, or mark your question as answered?
Thanks!

Damien,
I guess I was not very clear; basically I am suggesting the same thing as you in that you would use the same variable that stores the URL to pull in the canonical URL.
-
@elephantseo Would that not just point every product page to one URL if using one template?
Could you not add the canonical tag exactly the same way as you would add a unique Title or Description (that's if you have the ability for that)?
You'd have to have a database entry and when one of the particular pages loads you'd pull the desired canonical tag from the database for that 'page'.
EDIT - If you create a seperate template for each type of product then go with the template canonical URL
-
Add the rel canonical to your template so that whenever the ajax creates the new URL it already has the rel canonical pointing to the preferred page.

Rel=Canonical Vs. 301 for blog articles
Over the last few years, my company has acquired numerous different companies -- some of which were acquired before that. Some of the products acquired were living on their previous company's parent site vs. having their own site dedicated to the product. The decision has been made that each product will have their own site moving forward. Since the product pages, blog articles and resource center landing pages (ex. whitepapers LPs) were living on the parent site, I'm struggling with the decision to 301 vs. rel=canonical those pages (with the new site being self canonicaled). I'm leaning toward take-down and 301 since rel=canonicals are simply suggestions to Google and a new domain can get all the help it can to start ranking. Are there any cons to doing so?

Tools to scan entire site for duplicate content?
HI guys, Just wondering if anyone knows of any tools to scan a site for duplicate content (with other sites on the web). Looking to quickly identify product pages containing duplicate content/duplicate product descriptions for E-commerce based websites. I know copy scape can which can check up to 10,000 pages in a single operation with Batch Search. But just wondering if there is anything else on the market i should consider looking at? Cheers, Chris

Robots.txt & Duplicate Content
In reviewing my crawl results I have 5666 pages of duplicate content. I believe this is because many of the indexed pages are just different ways to get to the same content. There is one primary culprit. It's a series of URL's related to CatalogSearch - for example; http://www.careerbags.com/catalogsearch/result/index/?q=Mobile I have 10074 of those links indexed according to my MOZ crawl. Of those 5349 are tagged as duplicate content. Another 4725 are not. Here are some additional sample links: http://www.careerbags.com/catalogsearch/result/index/?dir=desc&order=relevance&p=2&q=Amy

http://www.careerbags.com/catalogsearch/result/index/?cat=9&color=241&dir=asc&order=relevance&q=baggallini All of these links are just different ways of searching through our product catalog. My question is should we disallow - catalogsearch via the robots file? Are these links doing more harm than good?0 -
Does having a page that ends with ? cause duplicate content?
I am working on a site that has lots of dynamic parameters. So lets say we have www.example.com/page?parameter=1 When the page has no parameters you can still end up at www.example.com/page? Should I redirect this to www.example.com/page/ ? Im not sure if Google ignores this, or if these pages need to be dealt with. Thanks

Wildcard Redirects & Canonical Tags
I have an interesting situation. Current URLs Example1: www.domain.com/red-widgets-cid-1234.html
Intermediate & Advanced SEO | | NakulGoyal
www.domain.com/red-widgets-cid-1234-1.html
www.domain.com/red-widgets-cid-1234-1-1.html Canonical on All Above URLs:
www.domain.com/red-widgets-cid-1234.html New URL:
www.domain.com/red-widgets-cid-4567.html Current URLs Example2: www.domain.com/red-widgets-cid-1234+10.html
www.domain.com/red-widgets-cid-1234+10-1.html
www.domain.com/red-widgets-cid-1234+10-1-1.html Canonical on All Above URLs:
www.domain.com/red-widgets-cid-1234+10.html New URL:
www.domain.com/red-widgets-cid-6789.html Current URLs Example3: www.domain.com/red-widgets-cid-1234+10+5.html
www.domain.com/red-widgets-cid-1234+10+5-1.html
www.domain.com/red-widgets-cid-1234+10+5-1-1.html Canonical on All Above URLs:
www.domain.com/red-widgets-cid-1234+10+5.html New URL:
www.domain.com/american-red-widgets-cid-6789+5.html I want to make sure all variations of the above URL redirect to the new URLs. However, as you see in Example 3, we are dealing with variables that are passed on. (+5 in this case). Question 1: What wildcard 301 redirect / regular expression can I use to tackle these ? Question 2: If we redirect www.domain.com/red-widgets-cid-1234+10+5.html to www.domain.com/red-widgets-cid-6789+5.html and www.domain.com/red-widgets-cid-6789+5.html contains the canonical tag www.domain.com/american-red-widgets-cid-6789+5.html, any concerns or red flags here ?0 -
Duplicate content in Webmaster tools, is this bad?
We launched a new site, and we did a 301 redirect to every page. I have over 5k duplicate meta tags and title tags. It shows the old page and the new page as having the same title tag and meta description. This isn't true, we changed the titles and meta description, but it still shows up like that. What would cause that?

Duplicate content mess
One website I'm working with keeps a HTML archive of content from various magazines they publish. Some articles were repeated across different magazines, sometimes up to 5 times. These articles were also used as content elsewhere on the same website, resulting in up to 10 duplicates of the same article on one website. With regards to the 5 that are duplicates but not contained in the magazine, I can delete (resulting in 404) all but the highest value of each (most don't have any external links). There are hundreds of occurrences of this and it seems unfeasible to 301 or noindex them. After seeing how their system works I can canonical the remaining duplicate that isn't contained in the magazine to the corresponding original magazine version - but I can't canonical any of the other versions in the magazines to the original. I can't delete the other duplicates as they're part of the content of a particular issue of a magazine. The best thing I can think of doing is adding a link in the magazine duplicates to the original article, something along the lines of "This article originally appeared in...", though I get the impression the client wouldn't want to reveal that they used to share so much content across different magazines. The duplicate pages across the different magazines do differ slightly as a result of the different Contents menu for each magazine. Do you think it's a case of what I'm doing will be better than how it was, or is there something further I can do? Is adding the links enough? Thanks. 🙂

Does rel=canonical fix duplicate page titles?
I implemented rel=canonical on our pages which helped a lot, but my latest Moz crawl is still showing lots of duplicate page titles (2,000+). There are other ways to get to this page (depending on what feature you clicked, it will have a different URL) but will have the same page title. Does having rel=canonical in place fix the duplicate page title problem, or do I need to change something else? I was under the impression that the canonical tag would address this by telling the crawler which URL was the URL and the crawler would only use that one for the page title.
