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.

Page Indexing without content
Hello. I have a problem of page indexing without content. I have website in 3 different languages and 2 of the pages are indexing just fine, but one language page (the most important one) is indexing without content. When searching using site: page comes up, but when searching unique keywords for which I should rank 100% nothing comes up. This page was indexing just fine and the problem arose couple of days ago after google update finished. Looking further, the problem is language related and every page in the given language that is newly indexed has this problem, while pages that were last crawled around one week ago are just fine. Has anyone ran into this type of problem?

Duplicate Content on a Page Due to Responsive Version
What are the implications if a web designer codes the content of the site twice into the page in order to make the site responsive? I can't add the url I'm afraid but the H1 and the content appear twice in the code in order to produce both a responsive version and a desktop version. This is a Wordpress site. Is Google clever enough to distinguish between the 2 versions and treat them individually? Or will Google really think that the content has been repeated on the same page?

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.

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!

Duplicate Content issue
I have been asked to review an old website to an identify opportunities for increasing search engine traffic. Whilst reviewing the site I came across a strange loop. On each page there is a link to printer friendly version: http://www.websitename.co.uk/index.php?pageid=7&printfriendly=yes That page also has a link to a printer friendly version http://www.websitename.co.uk/index.php?pageid=7&printfriendly=yes&printfriendly=yes and so on and so on....... Some of these pages are being included in Google's index. I appreciate that this can't be a good thing, however, I am not 100% sure as to the extent to which it is a bad thing and the priority that should be given to getting it sorted. Just wandering what views people have on the issues this may cause?
