Masses (5,168 issues found) of Duplicate content.
-
Hi Mozzers,
I have a site that has returned 5,168 issues with duplicate content.
Where would you start?
I started sorting via High page Authority first the highest being 28 all the way down to 1. I did want to use the rel=canonical tag as the site has many redirects already.
The duplicates are caused by various category and cross category pages and search results such as ....page/1?show=2&sort=rand.
I was thinking of going down the lines of a URL rewrite and changing the search anyway. Is it work redirecting everything in terms of results versus the effort of changing all the 5,168 issues?
Thanks

Hi Guys,
Thanks for the responses I'm going to have a look at the issue again, with your suggestions in mind. And I'll keep you posted. Thanks again.

Don't look at individual URLs - at the scale of 5K plus, look at your site architecture and what kind of variants you're creating. For example, if you know that the show= and sort= parameter are a possible issue, you could go to Google and enter something like:
site:example.com inurl:show=
(warning: it will return pages with the word "show" in the URL, like "example.com/show-times" - not usually an issue, but it can be on rare occasion).
That'll give you a sense of how many cases that one parameter is creating. Odds are, you'll find a couple that are causing 500+ of the 5K duplicates, so start with those.
Search pagination is very tricky - you could canonicalize to "View All" as Chris Hill said, you could NOINDEX pages 2+, or you could try Google's new (but very complicated way):
http://googlewebmastercentral.blogspot.com/2011/09/pagination-with-relnext-and-relprev.html
Problem is, that doesn't work on Bing and it's pretty easy to mess up.
The rel-canonical tag can scoop up sorts pretty well. You can also tell Google in Google Webmaster Tools what those parameters do, and whether to index them, but I've had mixed luck with that. If you're not having any serious problems, GWT is easy and worth a shot.

Have a look at your pagination too. If you've not got a 'show all' link it might be worth putting one in and making that the canonical. Should eliminate some of your duplicate content issues.
-
Last I came accross such an issue I mostly started with making the 'easy' changes that reduced the number the most.
In the last case, it was implimenting a 301 to the www version of the site (cutting the errors in half) and putting a canonical on one search page.
This got the number down to the point where it was easyer to make decisions on 'Is it worth making friendlyer urls' and discover more intresting places dup content was being generated.
It's one of these things I would always aim for 0 where I can. It usualy means that the url or site structure can be improved sugnificantly, or it's such an easy fix that it's hard to justify not doing.
-
If it really is a URL issue then you should just be able to easily canonical the root pages and the rest should sort itself out. Start there and let the next spidering tell you where you stand.

Duplicate Content from Wordpress Template
Hi Wondering if anyone can help, my site has flagged up with duplicate content on almost every page, i think this is because the person who set up the site created a lot of template pages which are using the same code but have slightly different features on. How would I go about resolving this? Would I need to recode every template page they have created?

"Daily Special" = Duplicate Content?
I believe this has been addresses and answered previously, but despite searching the Q&A archives, I was unable to find the question and answer. So, please be gentle and patient: We have an eCommerce site with several hundred products, most of which use the structure: www.mysite.com/subcategory/itemA.html. We wish to feature itemA as a "daily special" item, and our Magento developer has recommended: www.mysite.com/internet-daily-special/**itemA.html ** Because itemA.html is the same page—albeit following a different path—will Google see this as duplicate content? Thanks.

Testing for duplicate content and title tags
Hi there, I have been getting both Duplicate Page content and Duplicate Title content warnings on my crawl diagnostics report for one of my campaigns. I did my research, and implemented the preferred domain setting in Webmaster Tools. This did not resolve the crawl diagnostics warnings, and upon further research I discovered the preferred domain would only be noted by Google and not other bots like Roger. My only issue was that when I ran an SEOmoz crawl test on the same domain, I saw none of the duplicate content or title warnings yet they still appear on my crawl diagnostics report. I have now implemented a fix in my .htaccess file to 301 redirect to the www. domain. I want to check if it's worked, but since the crawl test did not show the issue last time I don't think I can rely on that. Can you help please? Thanks, Claire

How to use internal tracking without causing duplicate content issues
Hi, We've been testing internal tracking for 4 weeks on a couple of pages using the basic string ?internalcampaign=X, but hese pages have started appearing in the search results. We don't currently have the facility to add canonical tags to correct this. Does anyone have any other solutions to this problem other than deleting the internal tracking or adding filters on the server? Thanks!

Duplicate Content Issue
Hello, We have many pages in our crawler report that are showing duplicate content. However, the content is not duplicateon the pages. It is somewhat close, but different. I am not sure how to fix the problem so it leaves our report. Here is an example. It is showing these as duplicate content to each other. www.soccerstop.com/c-119-womens.aspx www.soccerstop.com/c-120-youth.aspx www.soccerstop.com/c-124-adult.aspx Any help you could provide would be most appreciated. I am going through our crawler report and resolving issues, and this seems to be big one for us with lots in the report, but not sure what to do about it. Thanks

Aspx filters causing duplicate content issues
A client has a url which is duplicated by filters on the page, for example: - http://www.example.co.uk/Home/example.aspx is duplicated by http://www.example.co.uk/Home/example.aspx?filter=3 The client is moving to a new website later this year and is using an out-of-date Kentico CMS which would need some development doing to it in order to enable implementation of rel canonical tags in the header, I don't have access to the server and they have to pay through the nose everytime they want the slightest thing altering. I am trying to resolve this duplicate content issue though and am wondering what is the best way to resolve it in the short term. The client is happy to remove the filter links from the page but that still leaves the filter urls in Google. I am concerned that a 301 redirect will cause a loop and don't understand the behaviour of this type of code enough. I hope this makes sense, any advice appreciated.
