Duplicate Page Content for sorted archives?
-
Experienced backend dev, but SEO newbie here
When SEOmoz crawls my site, I get notified of DPC errors on some list/archive sorted pages (appending ?sort=X to the url).
The pages all have rel=canonical to the archive home.
Some of the pages are shorter (have only one or two entries).
Is there a way to resolve this error? Perhaps add rel=nofollow to the sorting menu? Or perhaps find a method that utilizes a non-link navigation method to sort / switch sorted pages?
No issues with duplicate content are showing up on google webmaster tools.
Thanks for your help!

Cool, ill dig them out and fire over. Thanks. Marcus

If you've got a couple of examples, I'd be happy to take a look and/or ping the Product team. Just DM me or email at [peter at seomoz dot org].

Hey Peter
I have had this a problem a couple of times when it is not picking up on the canonical tag, any ideas what could cause that?
Cheers
Marcus

Actually, except in isolated cases, I believe we do parse rel=canonical. I know there are some weird exceptions (such as conflicting canonical tags).
Agreed, though, that the canonical itself should be fine in this case. You could block your sorting from the crawl by putting it in pull-down, for example (not create the URL at all). You could also block the sort= parameter in Google Webmaster Tools. Generally, though, I like canonical better than GWT for this.

Thank you, Marcus, that helped a great deal!
They both show the correct URL, so I'll disregard those errors

Annoyingly, the SEOMOz crawler does not yet take the rel=canonical into account so creates these misleading reports.
You can always check to see if both pages are indexed in Google to make sure they are only indexing the correct one to be sure
info:www.url.com/page.php?sort=x
info:www.url.com/page.php
Both should just show the main URL without the ?sort=x name / value pair and if so, Google is correctly referring the value of the sorted page to the archive home.
Hope that helps!
Marcus

Duplicate content question...
I have a high duplicate content issue on my website. However, I'm not sure how to handle or fix this issue. I have 2 different URLs landing to the same page content. http://www.myfitstation.com/tag/vegan/ and http://www.myfitstation.com/tag/raw-food/ .In this situation, I cannot redirect one URL to the other since in the future I will probably be adding additional posts to either the "vegan" tag or the "raw food tag". What is the solution in this case? Thank you

Would Google Call These Pages Duplicate Content?
Our Web store, http://www.audiobooksonline.com/index.html, has struggled with duplicate content issues for some time. One aspect of duplicate content is a page like this: http://www.audiobooksonline.com/out-of-publication-audio-books-book-audiobook-audiobooks.html. When an audio book title goes out-of-publication we keep the page at our store and display a http://www.audiobooksonline.com/out-of-publication-audio-books-book-audiobook-audiobooks.html whenever a visitor attempts to visit a specific title that is OOP. There are several thousand OOP pages. Would Google consider these OOP pages duplicate content?

We have set up 301 redirects for pages from an old domain, but they aren't working and we are having duplicate content problems - Can you help?
We have several old domains. One is http://www.ccisound.com - Our "real" site is http://www.ccisolutions.com The 301 redirect from the old domain to the new domain works. However, the 301-redirects for interior pages, like: http://www.ccisolund.com/StoreFront/category/cd-duplicators do not work. This URL should redirect to http://www.ccisolutions.com/StoreFront/category/cd-duplicators but as you can see it does not. Our IT director supplied me with this code from the HT Access file in hopes that someone can help point us in the right direction and suggest how we might fix the problem: RewriteCond%{HTTP_HOST} ccisound.com$ [NC] RewriteRule^(.*)$ http://www.ccisolutions.com/$1 [R=301,L] Any ideas on why the 301 redirect isn't happening? Thanks all!

Is 100% duplicate content always duplicate?
Bit of a strange question here that would be keen on getting the opinions of others on. Let's say we have a web page which is 1000 lines line, pulling content from 5 websites (the content itself is duplicate, say rss headlines, for example). Obviously any content on it's own will be viewed by Google as being duplicate and so will suffer for it. However, given one of the ways duplicate content is considered is a page being x% the same as another page, be it your own site or someone elses. In the case of our duplicate page, while 100% of the content is duplicate, the page is no more than 20% identical to another page so would it technically be picked up as duplicate. Hope that makes sense? My reason for asking is I want to pull latest tweets, news and rss from leading sites onto a site I am developing. Obviously the site will have it's own content too but also want to pull in external.

Noindex duplicate content penalty?
We know that google now gives a penalty to a whole duplicate if it finds content it doesn't like or is duplicate content, but has anyone experienced a penalty from having duplicate content on their site which they have added noindex to? Would google still apply the penalty to the overall quality of the site even though they have been told to basically ignore the duplicate bit. Reason for asking is that I am looking to add a forum to one of my websites and no one likes a new forum. I have a script which can populate it with thousands of questions and answers pulled direct from Yahoo Answers. Obviously the forum wil be 100% duplicate content but I do not want it to rank for anyway anyway so if I noindex the forum pages hopefully it will not damage the rest of the site. In time, as the forum grows, all the duplicate posts will be deleted but it's hard to get people to use an empty forum so need to 'trick' them into thinking the section is very busy.

The Bible and Duplicate Content
We have our complete set of scriptures online, including the Bible at http://lds.org/scriptures. Users can browse to any of the volumes of scriptures. We've improved the user experience by allowing users to link to specific verses in context which will scroll to and highlight the linked verse. However, this creates a significant amount of duplicate content. For example, these links: http://lds.org/scriptures/nt/james/1.5 http://lds.org/scriptures/nt/james/1.5-10 http://lds.org/scriptures/nt/james/1 All of those will link to the same chapter in the book of James, yet the first two will highlight the verse 5 and verses 5-10 respectively. This is a good user experience because in other sections of our site and on blogs throughout the world webmasters link to specific verses so the reader can see the verse in context of the rest of the chapter. Another bible site has separate html pages for each verse individually and tends to outrank us because of this (and possibly some other reasons) for long tail chapter/verse queries. However, our tests indicated that the current version is preferred by users. We have a sitemap ready to publish which includes a URL for every chapter/verse. We hope this will improve indexing of some of the more popular verses. However, Googlebot is going to see some duplicate content as it crawls that sitemap! So the question is: is the sitemap a good idea realizing that we can't revert back to including each chapter/verse on its own unique page? We are also going to recommend that we create unique titles for each of the verses and pass a portion of the text from the verse into the meta description. Will this perhaps be enough to satisfy Googlebot that the pages are in fact unique? They certainly are from a user perspective. Thanks all for taking the time!

Duplicate content question with PDF
Hi, I manage a property listing website which was recently revamped, but which has some on-site optimization weaknesses and issues. For each property listing like http://www.selectcaribbean.com/property/147.html there is an equivalent PDF version spidered by google. The page looks like this http://www.selectcaribbean.com/pdf1.php?pid=147 my question is: Can this create a duplicate content penalty? If yes, should I ban these pages from being spidered by google in the robots.txt or should I make these link nofollow?
