Strange duplicate content issue
-
Hi there,
SEOmoz crawler has identified a set of duplicate content that we are struggling to resolve.
For example, the crawler picked up that this page www. creative - choices.co.uk/industry-insight/article/Advice-for-a-freelance-career is a duplicate of this page www. creative - choices.co.uk/develop-your-career/article/Advice-for-a-freelance-career.
The latter page's content is the original and can be found in the CMS admin area whilst the former page is the duplicate and has no entry in the CMS. So we don't know where to begin if the "duplicate" page doesn't exist in the CMS.
The crawler states that this page www. creative-choices.co.uk/industry-insight/inside/creative-writing is the referrer page. Looking at it, only the original page's link is showing on the referrer page, so how did the crawler get to the duplicate page?

it could be any one out of the following 3 scenarios.
1: The page in question was moved at some point and since the CMS still accepts the old URL, when google re-visits the old URL it still finds it. So in this scenario it will find both the old URL and the new URL and index both.
2: google hasn't revisited the page for a long while but it is still in it's index, even though it would get a 301 by the CMS when it visits the page. Can be easily fixed by going to webmaster tools and ask it to remove it from the index.
3: there are still links to the old URL either on site or off site and since the CMS doesn't 301 the oid page it will index it again with a new URL.
4:the page still exists in the CMS because of some strange setting or equivalent in the CMS.
as mentioned before the easy fix is to use a robots.txt and deny access to the page and ask google to remove it from it's index. the better fix is to find the problem in the CMS and solve it. a midway fix could be to 301 it in the .htaccess or equvilent on an ISS server.
hope it helped

Thanks René,
I updated my earlier reply with a question that i think you missed.
The list isn't growing, which is a good thing but how is it possible for the crawler to pick up the duplicate page urls when the the referrer page has the correct urls?

I have come across this sort of issue a gazillion times + infinite.. almost all of our clients seem to have dub cont problems of one kind or another
but often it is different things that is the problem. But I'm afraid that I can't point you in the right direction, since I have no experience with your CMS. To be able to do that I would need to have access to the site itself. (since I don't know the CMS.) My advice would be to get a developer on the issue or to grab hold of the support for the CMS (if any.)

Hi René,
Thanks for your reply and suggestions. It could well be CMS remembering old urls as this list isn't growing. But is the crawler able to pickup the old urls when the referrer page has the correct urls?
We are on Expression Engine. Have you come across this sort of issue before?

Well it kinda have to be in the CMS, since it has 2 different paths.. But you could fix it by going to the .htaccess (if you have access and redirect it to the right URL and make a robots.txt and disallow access to the page.
if the page has been moved to a new location theres a good chance that the CMS is setup to remember the old URL and show the page. This is indeed a problem, but a potential problem with the CMS.
Go to webmaster tools and ask them to delete the dublicate from thier index.
You specific problem could originate from a ton of different problems and it is kinda har to fix without direct access to everything. What CMS is it your using?

ViewState and Duplicate Content
Our site keeps getting duplicated content flagged as an issue... however, the pages being grouped together have very little in common on-page. One area which does seem to recur across them is the ViewState. There's a minimum of 150 lines across the ones we've investigated. Could this be causing the reports?

Duplicate content
Hello mozzers, I have an unusual question. I've created a page that I am fully aware that it is near 100% duplicate content. It quotes the law, so it's not changeable. The page is very linkable in my niche. Is there a way I can build quality links to it that benefit my overall websites DA (i'm not bothered about the linkable page being ranked) without risking panda/dupe content issues? Thanks, Peter

Development Website Duplicate Content Issue
Hi, We launched a client's website around 7th January 2013 (http://rollerbannerscheap.co.uk), we originally constructed the website on a development domain (http://dev.rollerbannerscheap.co.uk) which was active for around 6-8 months (the dev site was unblocked from search engines for the first 3-4 months, but then blocked again) before we migrated dev --> live. In late Jan 2013 changed the robots.txt file to allow search engines to index the website. A week later I accidentally logged into the DEV website and also changed the robots.txt file to allow the search engines to index it. This obviously caused a duplicate content issue as both sites were identical. I realised what I had done a couple of days later and blocked the dev site from the search engines with the robots.txt file. Most of the pages from the dev site had been de-indexed from Google apart from 3, the home page (dev.rollerbannerscheap.co.uk, and two blog pages). The live site has 184 pages indexed in Google. So I thought the last 3 dev pages would disappear after a few weeks. I checked back late February and the 3 dev site pages were still indexed in Google. I decided to 301 redirect the dev site to the live site to tell Google to rank the live site and to ignore the dev site content. I also checked the robots.txt file on the dev site and this was blocking search engines too. But still the dev site is being found in Google wherever the live site should be found. When I do find the dev site in Google it displays this; Roller Banners Cheap » admin dev.rollerbannerscheap.co.uk/ A description for this result is not available because of this site's robots.txt – learn more. This is really affecting our clients SEO plan and we can't seem to remove the dev site or rank the live site in Google. In GWT I have tried to remove the sub domain. When I visit remove URLs, I enter dev.rollerbannerscheap.co.uk but then it displays the URL as http://www.rollerbannerscheap.co.uk/dev.rollerbannerscheap.co.uk. I want to remove a sub domain not a page. Can anyone help please?

Advice on Duplicate Page Content
We have many pages on our website and they all have the same template (we use a CMS) and at the code level, they are 90% the same. But the page content, title, meta description, and image used are different for all of them. For example - http://www.jumpstart.com/common/find-easter-eggs

http://www.jumpstart.com/common/recognize-the-rs We have many such pages. Does Google look at them all as duplicate page content? If yes, how do we deal with this?0 -
Avoiding duplicate content on internal pages
Lets say I'm working on a decorators website and they offer a list of residential and commercial services, some of which fall into both categories. For example "Internal Decorating" would have a page under both Residential and Commercial, and probably even a 3rd general category of Services too. The content inside the multiple instances of a given page (i.e. Internal Decorating) at best is going to be very similar if not identical in some instances. I'm just a bit concerned that having 3 "Internal Decorating" pages could be detrimental to the website's overall SEO?

404's and duplicate content.
I have real estate based websites that add new pages when new listings are added to the market and then deletes pages when the property is sold. My concern is that there are a significant amount of 404's created and the listing pages that are added are going to be the same as others in my market who use the same IDX provider. I can go with a different IDX provider that uses IFrame which doesn't create new pages but I used a IFrame before and my time on site was 3min w/ 2.5 pgs per visit and now it's 7.5 pg/visit with 6+min on the site. The new pages create new content daily so is fresh content and better on site metrics (with the 404's) better or less 404's, no dup content and shorter onsite metrics better? Any thoughts on this issue? Any advice would be appreciated
