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.

Duplicate content question
Hey Mozzers! I received a duplicate content notice from my Cycle7 Communications campaign today. I understand the concept of duplicate content, but none of the suggested fixes quite seems to fit. I have four pages with HubSpot forms embedded in them. (Only two of these pages have showed up so far in my campaign.) Each page contains a title (Content Marketing Consultation, Copywriting Consultation, etc), plus an embedded HubSpot form. The forms are all outwardly identical, but I use a separate form for each service that I offer. I’m not sure how to respond to this crawl issue: Using a 301 redirect doesn’t seem right, because each page/form combo is independent and serves a separate purpose. Using a rel=canonical link doesn’t seem right for the same reason that a 301 redirect doesn’t seem right. Using the Google Search Console URL Parameters tool is clearly contraindicated by Google’s documentation (I don’t have enough pages on my site). Is a meta robots noindex the best way to deal with duplicate content in this case? Thanks in advance for your help. AK

If content is at the bottom of the page but the code is at the top, does Google know that the content is at the bottom?
I'm working on creating content for top category pages for an ecommerce site. I can put them under the left hand navigation bar, and that content would be near the top in the code. I can also put the content at the bottom center, where it would look nicer but be at the bottom of the code. What's the better approach? Thanks for reading!

404 and Duplicate Content.
I just submitted my first campaign. And it's coming up with a LOT of errors. Many of them I feel are out of my control as we use a CMS for RV dealerships. But I have a couple of questions. I got a 404 error and SEO Moz tells me the link, but won't tell me where that link originated from, so I don't know where to go to fix it. I also got a lot of duplicate content, and it seems a lot of them are coming from "tags" on my blog. Is that something I should be concerned about? I will have a lot more question probably as I'm new to using this tool Thanks for the responses! -Brandon here is my site: floridaoutdoorsrv.com I welcome any advice or input!

Duplicate Footer Content
A client I just took over is having some duplicate content issues. At the top of each page he has about 200 words of unique content. Below this is are three big tables of text that talks about his services, history, etc. This table is pulled into the middle of every page using php. So, he has the exact same three big table of text across every page. What should I do to eliminate the dup content. I thought about removing the script then just rewriting the table of text on every page... Is there a better solution? Any ideas would be greatly appreciated. Thanks!
