404 Error Pages being picked up as duplicate content
-
Hi,
I recently noticed an increase in duplicate content, but all of the pages are 404 error pages.
For instance, Moz site crawl says this page: https://www.allconnect.com/sc-internet/internet.html has 43 duplicates and all the duplicates are also 404 pages (https://www.allconnect.com/Coxstatic.html for instance is a duplicate of this page).
Looking for insight on how to fix this issue, do I add an rel=canonical tag to these 60 error pages that points to the original error page?
Thanks!

I just did a check and you're right, even though these pages are showing up as errors to the user they are actually showing up as 200 OK, which is causing the duplicate content issue.
Thank you!

kfallconnect, if the 404 errors are being picked up as duplicate content, then most likely they're not actually showing up as 404 error pages. It's quite possible that it's a 404 error on the site (that's what the user sees) but, in fact, the server header is not displaying a 404 error. It could be showing up as a "200 OK".
First, I would identify the pages. If the user sees an error on the page, then that's fine. Use a server header check tool to see what the response code is when someone goes to the page. You can use something like Rex Swain's HTTP header tool to check it: http://www.rexswain.com/httpview.html . If the page shows a 404 error then you should be fine, it's not duplicate content.
If the page is showing a "200 OK" then it most likely IS duplicate content. If the page is showing an error to users but showing a '200 OK' in the server header, then that needs to be fixed.
But if the page is showing actual content (and not an error to visitors) then you need to look at potentially using the canonical tag or removing the content on the site completely (which is preferred).

I have not used Drupal for a couple of years, but there used to be a plugin called Fast 404 for some versions. Need to check whether suitable and if it weighs downs page speed. Zach is right if you can manually handle it do so, but if not perhaps research a plugin and research side effects.

We run on Drupal so I'm not sure if there is a 404 plug in
-
I had some issues with 404 errors as well.
Not sure how your site is set up but I just added permanent redirects on all the 404 duplicates I was having. I didn't have as many as you so it was pretty easy to do. I'm not sure if this is the 100% correct way of doing it but it fixed my issue.
Hope it helps!

I am not sure of the site is wordpress but have you considered 'smart 404' plugin. Could consider adding to the site, a solution.
Hope that assists.
Regards

Car Dealership website - Duplicate Page Content Issues
Hi, I am currently working on a large car dealership website. I have just had a Moz crawl through and its flagging a lot of duplicate page content issues, these are mostly for used car pages. How can I get round this as the site stocks many of the same car, model, colour, age, millage etc. Only unique thing about them is the reg plate. How do I get past this duplicate issue if all the info is relatively the same? Anyone experienced this issue when working on a car dealership website? Thank you.

Handling of Duplicate Content
I just recently signed and joined the a-moz.groupbuyseo.org system. During the initial report for our web site it shows we have lots of duplicate content. The web site is real estate based and we are loading IDX listings from other brokerages into our site. If though these listings look alike, they are not. Each has their own photos, description and addresses. So why are they appear as duplicates – I would assume that they are all too closely related. Lots for Sale primarily – and it looks like lazy agents have 4 or 5 lots and input the description the same. Unfortunately for us, part of the IDX agreement is that you cannot pick and choose which listings to load and you cannot change the content. You are either all in or you cannot use the system. How should one manage duplicate content like this? Or should we ignore it? Out of 1500+ listings on our web site it shows 40 of them are duplicates.

Duplicate Page Content and Titles from Weebly Blog
Anyone familiar with Weebly that can offer some suggestions? I ran a crawl diagnostics on my site and have some high priority issues that appear to stem from Weebly Blog posts. There are several of them and it appears that the post is being counted as "page content" on the main blog feed and then again when it is tagged to a category. I hope this makes sense, I am new to SEO and this is really confusing. Thanks!

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!

Squarespace Duplicate Content Issues
My site is built through squarespace and when I ran the campaign in SEOmoz...its come up with all these errors saying duplicate content and duplicate page title for my blog portion. I've heard that canonical tags help with this but with squarespace its hard to add code to page level...only site wide is possible. Was curious if there's someone experienced in squarespace and SEO out there that can give some suggestions on how to resolve this problem? thanks
