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.

What should I do with all these 404 pages?
I have a website that Im currently working on that has been fairly dormant for a while and has just been given a face lift and brought back to life. I have some questions below about dealing with 404 pages. In Google WMT/search console there are reports of thousands of 404 pages going back some years. It says there are over 5k in total but I am only able to download 1k or so from WMT it seems. I ran a crawl test with Moz and the report it sent back only had a few hundred 404s in, why is that? Im not sure what to do with all the 404 pages also, I know that both Google and Moz recommend a mixture of leaving some as 404s and redirect others and Id like to know what the community here suggests. The 404s are a mix of the following: Blog posts and articles that have disappeared (some of these have good back-links too) Urls that look like they used to belong to users (the site used to have a forum) which where deleted when the forum was removed, some of them look like they were removed for spam reasons too eg /user/buy-cheap-meds-online and others like that Other urls like this /node/4455 (or some other random number) Im thinking I should permanently redirect the blog posts to the homepage or the blog but Im not sure what to do about all the others? Surely having so many 404s like this is hurting my crawl rate?

Big page of clients - links to individual client pages with light content - not sure if canonical or no-follow - HELP
Not sure what best practice here is: http://www.5wpr.com/clients/ Is this is a situation where I'm best off adding canonical tags back to the main clients page, or to the practice area each client falls under? No-following all these links and adding canonical? No-follow/No-index all client pages? need some advice here...

Strange 404 Error(Answered)

http://www.directcolors.com/applications/concrete-countertops/top I understand that the **top **could be referring to an actual link that brings users to the top of a page, but on these pages there is no such link. Am I missing something?1 -
404 Error from site - is this normal?
I have been trying to clean up any 404 errors. We keep getting the following: URL /include/vdimgck.php referring domain http://www.856d.c@m/plus/feedback.php rendered domain unclickable by adding the "@" since I do not know if it is safe. I just turned off the trackbacks and pings in the blog since I saw it was producing duplicate content and from what I read it is not worth keeping those with Wordpress. is vdimgck.php anything some here instantly recognizes ? It tops all our 404 errors, seems like a lot of requests. Thanks!

How to avoid 404 errors when taking a page off?
So... We are running a blog that was supposed to have great content. Working at SEO for a while, I discovered that is too much keyword stuffing and some SEO shits for wordpress, that was supposed to rank better. In fact. That worked, but I'm not getting the risk of getting slaped by the Google puppy-panda. So we decided to restard our blog from zero and make a better try. So. Every page was already ranking in Google. SEOMoz didn't make the crawl yet, but I'm really sure that the crawlers would say that there is a lot of 404 errors. My question is: can I avoid these errors with some tool in Google Webmasters in sitemaps, or shoud I make some rel=canonicals or 301 redirects. Does Google penalyses me for that? It's kinda obvious for me that the answer is YES. Please, help 😉

Duplicate Page Content and Title for product pages. Is there a way to fix it?
We we're doing pretty good with our SEO, until we added product listing pages. The errors are mostly Duplicate Page Content/Title. e.g. Title: Masterpet | New Zealand Products MasterPet Product page1 MasterPet Product page2 Because the list of products are displayed on several pages, the crawler detects that these two URLs have the same title. From 0 Errors two weeks ago, to 14k+ errors. Is this something we could fix or bother fixing? Will our SERP ranking suffer because of this? Hoping someone could shed some light on this issue. Thanks.

Different TLD's same content - duplicate content? - And a problem in foreign googles?
Hi, Operating from the Netherlands with customers troughout Europe we have for some countries the same content. In the netherlands and Belgium Dutch is spoken and in Germany and Switserland German is spoken. For these countries the same content is provided. Does Google see this as duplicate content?
