Should there be a canonical tag on my 404 error page?
-
In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's?
Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page?
Thanks.

I repeated this elsewhere, but I think canonical on 404 page does make sense, especially if you consider the following two statements true:
- There is a reason for 404s, don't 301 everything
- There is no reason to lose the value of someone linking to your page.
If those 2 statements are true then you should create an individual error page, and then everytime you serve a 404 you should include canonical to that error page. That page should have useful content (explanation of page missing and where you could go), probably a search box, and links to the most valuable content on your site. This satisfies both points.
-
1 there is no point having canonical on a 404 page. I would say its a very confusing signal to bots
2 don't always 301. 404 exists for a reason. In most cases I will 301 old pages but there are cases where letting pages 404 is the correct way forward
-
If the old pages are NOINDEX, are the old inbound links still passed on to the new page via the 301's. and is the google juice passed? I've wanted to do exactly what you suggest, but was afraid of severing the Linking credit from those old inbounds.
-
The canonical tag on errorpages make no sense! For gone webpages just setup a 301 redirect in the .htaccess. And make use of the Google webmaster tools to identify waht Google sees.
-
Discovering 404s can be useful.
Is the old page deleted? Why not 301 redirect the URL to an appropriate page elsewhere on your site? Tools such as Screaming Frog's SEO Spider can crawl your website and help you discover 404s. By redirecting the page with a permanent redirect search engines will to pass any link juice the previous page had to the new page. Redirecting will also cleanup your pages in the SERPs and help with any broken internal links on your site (though it'd be better to fix those).
There's no need to having a rel=canonical tag on a 404 page (but if you do, ensure the tag is for the page itself and not actual content on your site).
There's also no need for search engines to index your 404 page, so I suggest adding the meta NOINDEX tag to the page.

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!

Does Title Tag location in a page's source code matter?
Currently our meta description is on line 8 for our page - http://www.paintball-online.com/Paintball-Guns-And-Markers-0Y.aspx
Technical SEO | | IstoresincThe title tag, however sits below a bunch of code on line 237
Does the location of the title tag, meta tags, and any structured data have any influence with respect to SEO and search engines? Put another way, could we benefit from moving the title tag up to the top? I "surfed 'n surfed" and could not find any articles about this. I would really appreciate any help on this as our site got decimated organically last May and we are looking for any help with SEO. NIck

Best strategy to handle over 100,000 404 errors.
I recently been given a site that has over one-hundred thousand 404 error codes listed in Google Webmasters. It is really odd because according to Google Webmasters, the pages that are linking to these 404 pages are also pages that no longer exist (they are 404 pages themselves). These errors were a result of site migration that had occurred. Appreciate any input on how one might go about auditing and repairing large amounts of 404 errors. Thank you.

Is there a way of changing the Permalink without getting the 404 Error?
Hi, I am new to this all.. Is there a way of changing the permalink for example from: domain/content/ to domain/profile/ without receiving the 404 error message. It's just that since my website has been developed, some pages and their content have changed but the permalink still shows the name of the old page which may be confusing. Ps. Please use most simple language for explanations as I am really new to it. Thank you! Ve

Splitting Page Authority with two URLs for the same page.
Hello guys, My website is currently holding two different URLs for the same page and I am under the impression such set up is dividing my Page Authority and Link Juice. We currently have the following page with both URLs below: www.wbresearch.com/soldiertechnologyusa/home.aspx
Technical SEO | | JoaoPdaCosta-WBR
www.wbresearch.com/soldiertechnologyusa/ Analysing the page authority and backlinks I identified that we are splitting the amount of backlinks (links from sites, social media and therefore authority). "/home.aspx"
PA: 67
Linking Root Domains: 52
Total Links: 272 "/"
PA: 64
Linking Root Domains: 29
Total Links: 128 I am under the impression that if the URLs were the same we would maximise our backlinks and therefore page authority. My Question: How can I fix this? Should I have a 301 redirect from the page "/" to the "/home.aspx" therefore passing the authority and link juice of “/” directly to “/homes.aspx”? Trying to gather thoughts and ideas on this, suggestions are much appreciated? Thanks!0 -
Geotargeting duplicate content to different regions - href and canonical tag confusion
If you duplicate content onto a sub-folder for say a new US geotargeted site (to target kw spelling differences) and, in addition to GWT geotargeting settings, implement the 'Canonical' and 'Hreflang' tags on these new pages to show G different region and language version (en-us). Then does the original/main site similar pages also need to have canonical and href tags ? The main/original sites page I don't really want to target a specific country (although existing signals (hosting etc) will be UK (primary target of main site) but pages show up in other country searches too (which we want). Im presuming fine to leave the original/main site as it currently is although wording in google blog/webmaster central articles etc are a bit confusing hence why im asking for anyone elses opinion/input on this. Also is there are any benefit (or just best practice) to use 'www.example.com/en-us/...' in the subdirectory URL as opposed to just 'www.example.com/us/' many thanks in advance to any commentators 🙂
